Equipment & Techniques => Medium Format / Film / Digital Backs – and Large Sensor Photography => Topic started by: markymarkrb on September 13, 2011, 09:55:33 am

I am considering buying a medium format digital camera and really can't come up with a solution. I am primarily a landscape photographer. Here are my options:
CPO H3DII-50 with 80mm $18,000
CPO H4D-40 with 80mm $16,000
Pentax 645D with 55mm $11,250
I like that the 645D is weather sealed and the cheapest of them all with the same sensor as the 40. I do however, yearn for a future trade in opportunity that Hasselblad is so good at doing but is that worth $4,750? I don't know. I have used a h4d-40 before and it is a pretty impressive camera but I am wondering if it has been equally matched by the pentax in photo quality. Does anyone have any sound non-biased advice?
Thanks,
Mark

Well, advice will be very difficult. Hasselblad is a really good equipment, the peer for modifications to the firmware, H3DII50 gained much of the functionality. (Exposure time). H4D40 it is a really good piece of equipment, in my opinion the best in its class - would not venture to claim that the best camera produced by this brand so far. But since 40 million pixels is enough for you, you should consider a P45 + (bigger sensor, exposure time to 1 h) Do not rush the decision, test equipment in exactly the conditions corresponding to your operating mode. Good luck 8)

I can't promise unbiased advice (mine is in my signature). Instead I'll just let you know you'll get much better advice if you clearly lay out for the forum more information:
- what sort of photography you do today
- what volume of shooting do you do
- what elements of cameras you have owned have been important to you
- whether you think your interest in photography might expand/change or whether you are fairly locked into a genre/technique/usage (e.g. maybe today you have no interest in a technical camera but in a year you might)
- what other cameras (if any) you might keep to complement/supplement your MF gear
- if you have tried either (or any other) option and if so what your impressions were of the positives/negatives (you mention you tried the H4D and it is "impressive" - I agree but it would be useful when asking for input if you could be more specific with your observations on what was and wasn't working for you with the system so people can compare/contrast those details with the Pentax and other MF options).
- if you want to go it alone and learn entirely through forums/internet or whether you think you'd benefit from a dealer whose entire job is to make sure you get the right equipment for your needs and then get the most out of that equipment with the least effort and frustration (a loaded question to be sure, but trust me I've met and respected both kinds of people - some people really do just prefer a user manual and a forum to a personal point of contact)
- whether you've worked with Phocus or Capture One, would be willing to try them (they are the way to get the most out of Hassy/Phase/Leaf files) or would be absolutely adamant about converting in a generic convertor like LightRoom
The reason I say this is because there is no "best camera" there isn't even a "best camera for the money". There is only a "best tool for the job" and we need to know what "job" the "tool" will be used for. For instance if you shoot a significant percentage of your shots hand held in the rain (e.g. covering weather related stories for a magazine) then the Pentax's weather sealing will be - by itself - reason to buy the Pentax and you can forget about other criterium.
If your needs call for a system which can shoot tethered, use a technical camera, or sync with flash at all high speed then the Hassy (or one of the other MF options) is a much better choice.
If you like using unusual/3rd party lenses (which requires a body with a focal plane) then the Pentax (or one of the other MF options) is going to be a better choice.
So anyway, tell the forum more about you, and you'll get much more relevant advice!
I'd also (in a biased way) point out there there are a few other options in the same general range with their own advantages/disadvantages.
- New Leaf/Mamiya DM28+DF+80LS = $11k
- New Leaf/Mamiya DM40+DF+80LS = $17.5k
- A pre-owned Phase P40+ or P45 non plus, P45+ with body/lens for around the same as the H4D-40 kit (prices will vary on number of shots, warranty, and which of the three backs)
The DM28 kit is particularly interesting in that if you don't need the resolution of 40mp (and if you haven't experienced it you can't compare 28mp from a digital back to similar resolutions from a Canon/Nikon/Sony) then you'd get a system with much of the flexibility (multiple bodies, tech cameras, sync speed, dealer support, future upgrade value) of the Hassy for the cost of the Pentax (along with other advantages and disadvantages compared to either).
Unless you've specifically excluded them for a reason I'd include them in your research.

I can't speak about trade-in values--I usually hold on to my cameras for a long time and shifts in technology don't make predictions easy (who would have predicted a $10,000 40MP MFD camera?). Used Pentax glass is also cheaper than the Hasselblad optics, so I would factor that into your costs.
The Pentax makes great images. It is a modern camera with all the convenience and flexibility that comes with that--I did not think I would use half of the exposures modes, but have found situations for them all and customizing the dial operation is very nice. ISO up to 1600 with no limitation for exposure time I have found.
It is very comfortable in the field--easy to carry, easy to hold. I picked up a Pentax Refconverter 90 degree angle finder which is great for low or awkward camera positions--screws into the eyepiece and can rotate. The two tripod sockets are a really nice touch--it is nice having the camera right over the head with vertical images without any adapters and such. The electronic level is nice as well--yaw and pitch on the monitor and pitch in the viewfinder. The battery lasts forever--I have two batteries and have yet to exhaust one in a full day of shooting, but I have not gone through Winter. The batteries are cheap and relatively available as they fit the current line of Pentax DSLRs. There is even a GPS accessory to record the image location.
I have a three lens kit. The DFA 55mm, A 35mm, and A 120mm Macro. They are very nice lenses. Two A lenses are manual focus and I have not had problems focusing them (I am using the Pentax gridded screen), but there are also autofocus versions. I have heard good things about the zoom lenses and the ED telephotos. (The 45mm prime is universally panned as a dog.)
The only downside is write times for preview can be sluggish, but everybody is in a rush today...
But camera purchases are personal. I would try to get your hands on some MFD cameras and try them out (although I bought my camera blind [but not my first MFD]). MFD image quality is going to be great whatever you get. I don't think you are going to be disappointed whether you end up with a Pentax or a Hasselblad.

Doug has a great set of questions that if we were able to know the answer, would help justify a qualified response to your broader question of "which camera is right for me?"
It is incomplete to frame the price difference to a single thing (trade-in, upgrades, lens selection, etc.) as more factors may improve or reduce your value to the difference in acquisition cost.
Would like to help and see your replies to the questions above, I believe you will receive good advice from the readers.
It may be possible to get an idea of the workflow from shot to process using each of the solutions to confirm your decision.

Thanks for all of the great advice! I have not been able to come up with a solution to my style. Here are a few more things about me and I am hoping to get a few more opinions on which direction I should follow.
I currently own a Fuji GX617 with a few different lenses but almost always use the 105mm, which shoots about 89 degrees per shot. I can really say that the only type of photography I really enjoy is landscape photography. I like the adventure and bringing home and sharing what I saw in a big way. I am sold on medium format. My problem is that I am struggling with the post shooting process with film in today's world. Sending off the film and not being able to see what I got at the location has started to bother me a little too. Drum scanning for $150 a pop isn't really fun either and I have mixed feelings on the results. I think that shooting digital MF will at least cut out one step between the camera and the printer. I carry a Nikon D90 with me when I shoot just because I want to take something of the area that I was in in case I fail with film. I want to only carry one camera. I really like the 617 format and want to compromise by stitching with a medium format digital until technology and my budget catch up. I am hoping the RED 617 is in my future. Until then, I want a camera that can get good MF digital results, for a good price and won't loose too much value for a resale. I liked the H4D-40 when I used it but it seems to me that it is more of a studio camera and that most landscape photographers I see are using a Phase setup. Phocus is ok, I want to try Capture one but haven't done so yet. I really wouldn't mind going with a Pentax 645D if people thought the results they are getting are somewhat similar to a H4D. I don't know if this is enough or too much but that is where I am sitting. I really don't see myself spending more than 16K on this next purchase and that is a stretch as well. Thanks for reading.

Just out of curiosity, have you tried stitching with your D90?
Cheers,
Bernard
-
Mark, perhaps I can help. Here is a stitch I did with the DFA 55mm at f/11 and ISO 400 this weekend on a casual hike. The focus was set on the trees in the foreground. The pano is four horizontal images taken handheld--the gridded focus screen helps. Stitched in Photoshop with a cylindrical projection. Final size, 15,556x5,195 pixels. There are two 100% crops of the foreground trees and the bay so you can get an idea of the detail even with aerial haze (click on the thumbnails below).
I do use a nodal slide. I have an Arca Swiss P0 ball head and found the Manfrotto macro rail to be an good inexpensive nodal slide--I can use it with the DFA 55mm and A 35mm. Since the 645D has two tripod sockets, the macro rail is enough for both stitching vertical and horizontal camera orientations.
Oddly enough I have just made a similar jump. I sold my film gear and invested in the 645D--including my Horseman SW612 and Widelux. It has been a good move for me, but there it some getting used to. The camera is not really hard to use, but getting used to a digital workflow is taking some time. But I always go through a transition with a new camera or process.
About the budget. I also got two manual focus lenses with my 645D, a weatherproof IR remote, and an angle finder, which added about another $1,000 to the price. I like my A 35mm and A 120mm macro manual focus lenses--I use the macro for landscapes primarily. The AF versions are two to three time more expensive than their manual focus cousins.

Haha, great question. No, I have not stitched with it and really am not interested to. Going from MF film to stitching with the D90 would really not cut it for me.

In your quest here do NOT leave out a used P40 plus at around 13k for the back. It's a cropped sensor of the P65 and the IQ 160. I owned the P40 for over a year before moving up to the IQ 160. Great back , excellent quality and excellent files. I have had a lot of Phase backs for awhile now and still like them very much. As always try these cams out with there software and workflow and see if it fits your style. But I have owned this back and can only recommend it highly and the system. But for the money maybe one of the best backs out there, they are all good no question about it . You just need to handle them and see what works for ya and don't buy by price. Usually going MF you need to think system and all that is involved is the best choice. Good luck

Any Hassy will give you incredible colors right of the box. Phase only approaching that colors now with IQ180. Most Phase colors are very natural (like shot on Fuji Astia). But who wants that natural colors in landscape anyway? This is not jewelry catalogue shooting. You can rent Hassy lenses around the world. Pentax has noise in shadows at dim light and lenses sharpness could be better.
If weatherproof and light camera is your priority, go for Pentax. If you about colors and sharpness go for Hassy.

Hi Mark,
Not sure if we have addressed the 645D vs. the H4D-40 question for you in this thread - thanks for posting additional information.
Peter Lorber (another Hasselblad reseller down in Boca Raton FL) shoots landscape and in a big way; he has several photography workshops (http://www.peterlorber.com/bar-harbor-autumn-colors.html) that are centered around this discipline - not the least of which is an upcoming one to capture the fall foliage change.
You will find the Hasselblad is well suited for landscape photography and having carried one myself through Zion Canyon, is not as light as the Nikon, but the scenery justified the MF camera.
If the purpose of the camera is to shoot landscapes most of the time, but also to perform well in other shooting scenarios, then the next step is to select your resolution; 31, 40, 39, 50, 60. For reference in the Pentax price range, a new Hasselblad complete kit in the 31MP is $13995 and we have (2) H3DII-39 under $12995. We have addressed the value of used cameras in a separate forum and can provide guidance on the Hasselblad models if needed.
The longer exposures of the H4D-40 are beneficial if night photography is in your strategy - including the ISO 1600 for 20-30 second exposures that capture the Milky Way but avoid star trails due to Earth rotation.
Hope this helps,
John

John, stars can trail in 20-30 seconds. I use the Pentax 645D for wide-field astrophotography and you claim that you can shoot the Milky Way at ISO 1600 with a 20-30 second exposure is a bit of a stretch even wide open (which will show too many lens aberrations). You won't get enough data to define it in a single shot and stacking can only get so far. At ISO 1600, I routinely shoot 3-5 minute exposures for the Milky Way.
I won't say you can't do astrophotography with a Hasselblad, you can do it with many cameras, but what you are saying is really not very illuminating.

If weatherproof and light camera is your priority, go for Pentax. If you about colors and sharpness go for Hassy.

I would love to see some comparisons for low light. I shoot with the Pentax up to multi-minute exposures and have not really seen comparisons to the Hasselblad. Noise is really good in the Pentax, but it would be fun to see how much Hasselblad improves on that.
And can you show the difference in color palette? That would be interesting to see as well.
BTW, which Pentax and Hasselblad lenses did you compare?

I am considering buying a medium format digital camera and really can't come up with a solution. I am primarily a landscape photographer. Here are my options:
CPO H3DII-50 with 80mm $18,000
CPO H4D-40 with 80mm $16,000
Pentax 645D with 55mm $11,250
I like that the 645D is weather sealed and the cheapest of them all with the same sensor as the 40. I do however, yearn for a future trade in opportunity that Hasselblad is so good at doing but is that worth $4,750? I don't know. I have used a h4d-40 before and it is a pretty impressive camera but I am wondering if it has been equally matched by the pentax in photo quality. Does anyone have any sound non-biased advice?

I believe that the issue will be between the H4D-40 and the Pentax. I will not recommend the older technology, even more so taking into account the new firmware update. For me working linked to the computer is one of the strong points of medium format. Is far beyond the normal experience with my Nikons. You have full frame focus area plus other strong points. The pentax is not that good at it. The second point will be technical cameras. That is not important to me but maybe it is for you. Hasselblad has a bunch of interesting options including:
1. TS adapter.
2. GPS (just like Pentax)
3. You can power the camera from mains.
4. True focus.
5. The system has more than one camera, so if you need higher resolution for a particular Job you can rent just the body and use your expertise and lenses with the rented body.
On the other hand Pentax is a very modern camera with options etc, plus it will continue to benefit from the advances of 35mm SLR.
Best regards,
James

I am surprised nobody mentioned the Sinarback 75 or the Leaf 7 or even 75! The Sinar has the big advantage of the adapter, so it can be used with any camera! There is the P45+ long exposure advantage of course, but I don't feel that Extra long exposure is needed. My suggestion would be S/H with one of the above mentioned backs and Zeiss glass! So...., either Contax 645 or Hassy V. Cheers Theodoros, www.fotometria.gr

1) The lens focal lengths are not very close. You can buy from Japan the Pentax 75mm/2.8 new for something like 600-700 USD if you need that more than 55mm or you need both.
2) Secondly whilst nobody can claim to know the future I predict that the market for pre-owned MF cameras will forever change when the first wave of used 645D will hit the market (probably next year after Photokina). What would you personally chose today between a CPO Hasselblad H4D 40 w 80mm for 16K or a pre owned 645D+55mm for let's say 8K? I think that will give you an idea why there will be a lot harder for dealers and factories to push used (and pretty recent models) for today's prices. Thus it will be harder to offer as large as today discount for trade ins. What I am trying to say is that IMHO if you buy the H4D 40 tomorrow for 16K you will maybe able to sell it or trade in it in 18 months' time for 7-8K tops. Probably your 11K+ Pentax will be 6K+ in 18 months but you have a bigger chance that the next "New Pentax" will still cost half as much as the next "New Hasselblad" with the same or close sensor. Plus if you lose 5K USD in 18 months of usage thats under 10 dollars per day.
3) How much is a L plate for the Hasselblad (0 USD for the 645D)?
How much is the second battery pack for a Hasselblad (36 USD for Pentax) and how many shots will it get you at 20+ centigrade (800)? What about in the winter time? (still 650 or so for the Pentax at -10 centigrade)?
How much is the Hasselblad GPS unit (250 USD for Pentax')?
How much is a high performance 64GB CF card for Hasselblad vs. 2x32GB SDHC cards for Pentax?
4) The almost 1 kilo weight difference for the camera + lens is important to you?

Two blanket statements without any hard evidence to support them at all.
If weatherproof and light camera is your priority, go for Pentax. If you about colors and sharpness go for Hassy.
Another very shallow advice in fact Pentax has only two lenses that are weatherproofed and in equally skilled hands for most focal lengths the difference in sharpness and colors will probably be impossible to asses.
This year Mercedes-Benz A and C class catalog was shot on H4D-40.
That proves nothing except that the agency that has this account has a workflow based around Hasselblad gear or trusts another company to deliver the quality needed. BTW, I imagine that when working with inanimate objects like cars one can actually use the multishot features of other Hasselblad cameras. IMHO it will take a long time for lots of professionals to change their current systems regardless of any other offers because I imagine that even if the economy would be in excess of 50 000 USD or Euro the lost time used in modifying the workflow would cost much, much more. Maybe if one camera could do something that any other can there will be an incentive. On the other hand for a lot of amateurs and enthusiasts I bet that the "magic color souce" and "pixie dust" stories won't make up for the money difference.

That's a very strong points for the Pentax, price wise nothing can get it, plus the battery etc.
Few months ago I was making the point that Hasselblad could get sandwiched between Phase one on the top and Pentax on the bottom.
Looks like it's becoming so. But for some professional the Pentax simply will not cut it.
I Still believe that the H4D system remains completive. When the H4D-40 was introduced, for most medium format application,s the machine was a super strong proposition. Now is no longer clear.
That good for us, in the market sense, as users.
Finally the Elephant on the room:next generation Canon and Nikon systems. If the density of the new Sony cameras is any indication, the next generation will be monsters (24Mpixels with a crop sensor means 54mp full frame 35mm, but the industry is waiting for 30+ cameras)
If the CaNikons loose the antialias filter they will be killer machines, with killer lenses.
Medium format will continue to be a different medium, with a different set of specs and strengths , but it will be in a different position.
Best regards,
James

Or not. I saw the review of the new Sony 24MP sensor on LL. Yes it has 24MP, but it is not keeping up with the 24MP 35mm sensor it was compared with--the image was mushy--neither really compete with a Phase 25+ 24MP back either. Medium-format is not good because of the number of photo sites, but the size of the sensor. Lets just hope the new round of 35mm cameras are not a white elephant...

Hello Radu, welcome to the forum - many opinions and knowledge here to add to your experience.
If you have not seen the images from Hasselblad MF and need some example RAW files, we can provide for your review the evidence you seek in regards to color fidelity. Save the blankets for the cold weather!
Be well, stay creative!

BTW, which Pentax and Hasselblad lenses did you compare?
It's easy to find on picasaweb full resolution photos taken with SDM 55mm and HCD 28mm (like Mercedes 2012 catalog) to compare night shots and daylight shots. For small prints, like 16x20", whey are both great.
Don't get me wrong, 645D kit has great value for $11k, but it's not competitor for $20k H4D-40 camera from IQ point of view.
And in turn, the H4D-40 can't compete with p45+. As P45+ gives crystal clear shadows at night shots.

Or not. I saw the review of the new Sony 24MP sensor on LL. Yes it has 24MP, but it is not keeping up with the 24MP 35mm sensor it was compared with--the image was mushy--neither really compete with a Phase 25+ 24MP back either. Medium-format is not good because of the number of photo sites, but the size of the sensor. Lets just hope the new round of 35mm cameras are not a white elephant...
+++1. Just to add, its not only the above that is correct, it's also the lack of AA filters, the true 16bit, the luck of NR, the LPF... etc. Actually, nobody can appreciate MF unless he has used it. It's funny that there are people who think that MF DR, has anything to do with FF or APS-c. Perhaps its DXO to be blamed here, but shouldn't some people think "why so many top pros prefer MF than smaller?" Cheers, Theodoros. www.fotometria.gr
P.S. Just to correct the obvious typo, P25+ is 22mp.

Hello John and thank you for the welcome!
I am very aware that there is much more to learn and add to my very limited experience but I would prefer to do it from controlled tests that can show one system's advantage over another in terms of color accuracy and lens performance rather than from sentences like "brand A is the best, brand B not so much" (btw, that was NOT your sentence). I find it unfortunate that not even this site (IMO the Mecca of MF related stuff) cannot arrange for some comparative tests that could shed some light over the hard facts and remove any urban myths before they become to entrenched in the community mind.
Don't get me wrong I have nothing against Hasselblad it is only that besides the obvious advantages (tethering, "bigger" siblings in the family, much larger availability of lenses and accessories, pro support network, specialized lenses such as 100/2.2 and probably other things) I am still to see any evidence that from an iq point of view the H4D 40 can do better than the 645D. Maybe you can help me with that.
Best regards,
Radu

So actually, you don't have any direct comparisons to support your claim. Sorry, but looking at different photographs of different subjects shot under different conditions with different processing is not really evidence of anything. I have seen full-res images of different MFD cameras and nothing really stands out except that MFD can give very nice quality. What we really need is folks with first hand experience of these systems. Unfortunately, I have only used Pentax and Phase, but not Hasselblad, so I cannot give a comparison.

I find hard to believe that the Hasselblad has a big advantage over the Pentax in terms of IQ. This is based on a marketing analysis: In the old days, for people, Leaf use to have an advantage agains the other guys using Kodak sensors, and they put pictures (a lot of them vogue) for everyone to see.
We should expect that companies will point to strengths of the products they sale.
Hasselblad is all about hands on. My guess is that this is because they know they have a very strong system. In the other hand go to the Hasselblad web side, download the examples and you will see:
Two images with the H3D-31, one with H3DII-39, one with the H3D-39
Pretty old machines. It's unlikely that a company that actually believe they have a exceptional image quality will do something like that. All that pictures taken with discontinued machines. If you are right that fact don't make much sense, if we don't assume unusual things about Hasselblad management.
My guess is that Hasselblad is selling a system that is (or was) far ahead of the other medium format systems, with an inherent image quality well beyond that of 35mm DSLR and competitive with medium format alternatives. With pro support and multiple rental places.
Phase one was (is) selling a so called "open system", rugged, with excellent image quality with a strong system for landscape,architecture (technical cameras) and when combined with the H2 series for vogue. They also have Capture one.
Nowadays they are also selling on sensor technology that is ahead of the alternatives with prices to match.
Of course my objection is based on a marketing analysis, so it can never be as strong as a hands on, rigorous analysis , but it will be a shocking result.

James

There is no "true 16 bit" in any sensor made today, certainly not at the pixel level, especially not in any MFD sensor. While MFD sensors have an advantage on sensor area, they lack the competitive CMOS technology deployed in the smaller sensors. A full-frame Exmor sensor with 36+ MP would be a competitive offering much as the D3x is competitive with last year's MFD technology, which is to say that you will still have reasons to use both.

I've been using the Pentax 645D for about six months so far, and very much liking it, mostly for landscape work. Photography is a hobby, so I can't speak as a pro, and I've not used any other medium format systems to offer a comparison. My other system is Nikon (D700) with a full assortment of lenses, including the ZF primes. What tipped me to the 645D were a couple of points which aren't frequently mentioned: with a few adapters, the selection in glass can include Hasselblad V lenses CF, CFi CFE, Hasselblad F & FE, Pentax 67 and Pentacon Six lenses. There's a lot of great glass that can be put on the 645D, but it does take time and patience hunting down good clean copies. Some of them are down right bargins (although prices have spiked for the 645 lenses in the last year.) It isn't for everyone, and the manual focus (& manual exposure) make for a slower workflow. I find it works for me, for doing landscapes, cityscapes, and still life. The 645D does have a nice feature for exposure -- instead of spinning the front finger wheel to adjust shutter speed in manual mode, you can press the green dot button, and the camera will immediately set shutter speed to what it thinks is correct exposure for the current meter mode. You can then adjust from there with the finger wheel, if needed. This makes manual exposure much faster, especially when using the lenses that require manual stop down.
With dual SDHC slots, the 645D works well with an EyeFi card in the 2nd slot, so it is possible to wirelessly beam 10mpix jpegs over to an ipad for preview in the field via Shuttersnitch photo application. It isn't instant (10 - 20 seconds) but being able to view on a larger ipad screen is quite handy. The EyeFi appears as a WiFi hotspot so the ipad can directly connect without an internet connection. The full size 40mpix raw image is written to a regualr SDHC memory card in the 1st slot, to be manually downloaded later at home into Lightroom. Battery life, even with the wifi card, is pretty good -- good enough that I usually can get by with 2 batteries (in mild climate). The build and ease of use on the 645D is first class, and other than a few small differences, going from a D700 to the 645D took about a day or two to adjust. The 645D can do long exposures well -- I've done 30s-4m exposures in bulb mode, no problems. I normally use base ISO of 200, but going as high as ISO 800, the noise hasn't bothered me much (as long as you don't push too much in post).
I do wish that someone would make an adapter with mild tilt capabilities. I've seen the threads on modifying a 67 55mm using shims, but haven't tried it yet. The depth of field difference between the 645D, the FF D700, and the crop D300 is very noticable, and I find getting everything sharp requires a lot more attention (or, if subject allows, use multi-shot techniques and use focus stacking software...)
The Hasselblad PC Mutar shift adapter does indeed work on the 645D w/ 645-HB adapter, but it also adds an optical 1.4x tele-conversion.
Some examples are up here:

SMC Pentax-A 645 80-160mm 1:4.5 zoom
SMC Pentax-A 645 135mm 1:4 LS
SMC Pentax 67 165mm 1:2.8
SMC Pentax-A 645 150mm 1:3.5
SMC Pentax-A 645 200mm 1:4
*) To use the Hasselblad CF, CFi, CFE lenses, cock the lens if it isn't already, put on the PT645-HB adapter, mount lens + adapter to camera body, set the lens' shutter to use focal plane, open the lens aperature with the stop down lever, select desired aperture on the ring, focus while wide open, stop down aperture with the lever, set exposure, take the shot. When using the adapter with a Hasselblad lens on the 645D, there is no electrical or mechanical linkage between the lens and the body - the lens will not fire and should remain cocked. You're using the shutter in the camera, and stopping down the aperature on the lens manually. The Pentax 67 lenses are a bit more convienent -- you don't need to manually stop down, just select aperture with the ring on the lens, focus & expose, take the shot. In the case of 67 lenses with the right adapter, there is mechanical linkage so the camera can stop down the lens. The 645-A lenses have cpu contacts, so you can select both aperture and shutter speed with both finger wheels on the camera body. I haven't tried any of the 645 autofocus lenses. The 67 & Hasselblad adapters are from a company called Fotodiox. The adapters for Pentacon-Six to 645 can be obtained online from a few distributors in the Ukraine.

16Bit may have been an impression on me that marketing succeeded, if that's the case, ....thanks for the quote! The conclusion is still active (and it applies to the D3X as well, which I sold recently). Regards, Theodoros. www.fotometria.gr
