Aloha,
So what lenses will this camera be capable of using?
Thanks

Natively the Fuji new line up and the HC lenses. With 2 adapters stacked, any lens that can be mounted on a H6D should be mountable too.

Besides, that will depend on the adapters that will be created for it. The flange distance of the G mount is 26mm, which is 20mm less than F mount, 18mm less than EOS,... you can pretty much mount any of these also. I am sure that many 35mm lenses will have enough coverage for this small MF sensor.

I would be interested in being able to mount my Otus lenses on the Fuji, in particular my 28mm f1.4. This would be very interesting...

cheers,
Bernard

I would love to see a Mamiya/Phase One adapter with electronic aperture control.  That would make the GFX a cost effective and very credible back-up to an XF system... well I guess only if C1 Pro supported the GFX...

I think giving the Xpan lenses (~34mm flange distance, Fuji made!) a go on a GFX would be fun.  :)

So with the HC adapter it seems that AF is not available. That's not a killer deal breaker, but would it be possible to at some point make that available through firmware or is the technology completely different where it would not?

+1 on this.

I just wonder if releasing the G mount H adapter is one way of a shot over the bow of Hasselblad. As regards, Phase, we all know they could make an adapter today, but perhaps they are still wooing Phase to allow C1 usage of GFX RAW files in C1.

The again, perhaps it could be double edged sword where if GFX files can be used in C1 then no adapter will be released for Phase lenses. I have mixed feelings on what I would like to see if only one choice was possible, but right now I am leaning toward using Phase lenses on the GFX and back to LR I go.

We don't need a Fuji - phase adapter. We just need someone (like novoflex) to produce one.

Still are all rumors, but apparently picture were available until pulled sometime this am. 

Appears that Fuji is working lens adapter for several high end cameras including the Otis line up and Schneider LS glass.  They don't mention the P1 name, and the SK 35mm  lens mentioned shows F4 instead of the correct F3.5 (not aware of a different 35mm SK LS).  Still all good news.  Note, links are to a closed Facebook group, so currently you can't see the Schneider adapter.

The Schneider TS is the 28mm behemoth I am assuming...  That would make a very interesting architectural setup if it can still utilize the majority of the shift movement.  I would be very curious to see if this kind of solution minimizes color cast issues compared to sticking the 44mm sensor on tech cams as we've seen already.
Title: Re: Lenses for the gfx 50s
Post by: Paul2660 on January 31, 2017, 07:13:17 pm
The Schneider in the pics is actually a older lens, at least by the look of it.  Possibly a MF lens to start with. 

Not sure how the LS glass would work with an adapter, I guess if Fuji can get the Hasselblad leaf shutter to work, they might get the Schneider to work also? However Fuji has a bit more knowledge on the Hasselblad side since they made lenses for H for a long time.

Received a new video from a French dealer where he has all 6 lenses. That 110/2.0 looks to be the same size as the 32-64. The 32-64 lens he shows does not have internal focusing which I was lead to believe that lens actually was.  The lens data starts around 7 minutes.

I was considering selling mine considering how good the Nikon 105mm f1.4 is... but I'll probably keep it.

Also, the 28mm f1.4 may not be covering the full sensor of the Fuji wide open, but I am sure that it would stopped down, and that lens is so incredibly superior to other wides on the market that it could be something very special too.

I agree, and even wide open with a bit of a crop from 28 to 35 it will still be wide and awesome.

Bt at the same time i am holding off to see how the D810 successor looks too. The 810 and successors seems the safest and most logical camera to invest in these days in terms of future proofing etc.

Also interested in the 810 successor and also the A7Rll successor.  I have the MF end completely covered and own a couple of really nice lenses in 135 format including an Otis.  If I were to entertain one of the new MF mirrorless offerings it would be the GFX because of its flexibility.

The fuji has basically the same size as a D810. I would cancel my order in seconds were the D850 to be EVF based, but the odds are high that it will simply be the last OVF based DSLR, which would be pretty amazing already considering how great all the recent Nikkor lenses have been (starting with the new 70-200 f2.8 that can be best described as an Otus tele-zoom with best in class look, AF, VR and military grade build).

So we'll see. ;)

Assuming we will get a Canon EF - Fuji G adapter, 135mm lenses with sufficient image circle would be suitable for the Fuji GFX.
I tested quite a few 135mm lenses on my FPS IQ180. I cropped the test pics of the lenses with sufficient image circle to 44x33mm format to show some of the future options with that cool 44x33mm cam.

Canon EF 11-24f4
pics at f11
slight vignetting due to the sun shade
I assume no vignetting w/o sun shade

I don't have proper test pics to show corner sharpness but I think it's usable because others use that lens already w/ shift on the Sony A7Rii w/ 36x24mm sensor.
Title: Re: Lenses for the gfx 50s
Post by: chrismuc on February 05, 2017, 10:33:09 am
Leica R 28f2.8 @ f8
nearly but not fully covers 44x33mm

Leica R 28f2.8 PC @ f11
easily covers 44x33mm with good corner sharpness (but strong distortion)

Leica R 60f2.8 Macro
an unpredicted option
good corner sharpness, just slight vignetting that possibly is gone at short distance/macro
Title: Re: Lenses for the gfx 50s

Leica R 180f2.8 Apo @ f5.6
Leica R 180f3.4 Apo @ f5.6

both lenses cover 54x40mm, so 44x33mm is a piece of cake for them;-)

especially the legendary f3.4 version would be a reasonable priced tele option with excellent IQ for the Fuji

Sigma 35f1.4 Art @f1.4 and @ f11

both cover 44x33mm
at f1.4, the corners are a bit smeared and the 35 shows slight vignetting
closed down corner sharpness is astonishing good and no vignetting
Title: Re: Lenses for the gfx 50s
Post by: chrismuc on February 05, 2017, 10:46:46 am
Zeiss CY 135f2
Zeiss ZE 135f2 Apo

both cover well 44x33
the image circle of the older CY version is larger
the sharpness of the newer ZE/Milvus version is exceptional at any aperture

Zeiss CY 35f2.8 PC

being designed as a shift lens for 135 format, this lens of course covers 44x33mm with excellent sharpness all over the frame
the test pic is a 135 pano cropped to 48x24mm which equals the image circle of 44x33mm (= 55mm)

Having done adapted lenses with my m43 & Sony A7x cameras, I plan to take a pass with the Fuji. Except maybe for the Pentax 645 120/4 macro should the appropriate adapter appear. As small & portable as possible is what I'm aiming for.

This is very interesting since this lens, that I own in F mount, is IMHO the best 180mm ever by a significant margin.

I have canceled my GFX 50s order for now, but I'll consider again when F mount adapters start to appear.

Really, why may I ask? Is it to see what the new Nikon, if it shows up, can produce? Since I make a semi-living thru my landscape photography and would like to move from my old 1 DS Mark III, to a camera where I do not need to use my pano gear to get the size of files I require, would be interested in hearing your reasoning. :)

The reason has little to do with the Fuji in fact. I am the new owner of both a Sigma SD H and H6D-100c with matching lenses and I have decided to deep dive in them for now.

I am very happy about my first results with the Hasselblad, amazing viewfinder, accurate AF, great UI, usable handheld with very sharp results.

I'll most probably get the D810 replacement to continue to serve my full range of F mount lenses.

The Fuji may come at a later stage, we'll see. I am totally convinced it is an amazing camera system.

For the ones who wait for a Canon - GFX adapter:

1. A week ago I emailed Metabones and asked if they were planning to release a Canon - GFX adapter. Their answer:

"Thank you for your enquiry and interesting in our products.
Sorry to inform you that we do not have plan to release the adapter for Canon EF to Fuji GFX camera at this moment.
I am worry that the room of coverage of the Canon TS-E lenses can be reached the whole frame size of medium format.
We do not attempt to insert the lenses for enlarging the image due to the image quality is the most concern topic of our products.
Even if the coverage of TS-E is enough, we are not sure to demand for such product on the market can be covered our development cost, etc.
Anyway, we will have further study for the possibility to release the product against the GFX camera."

Their assumption about the image circle of the TS-Es is not correct. And there are lots of other full frame lenses who cover the sensor. So the people who wish for such an adapter should write to metabones too. Maybe if they know that there is demand, they rethink the decision.
 

2. Another company who could make a helpful product is cambo.
Cambo now announced a Canon lens panel for the WRS Series: https://blog.cambo.com/2017/02/10/cambo-wre-ca-lens-adaptor/
Works with the electronic shutter of the IQ 3100 only (because of the lack of a shutter). Clever design. Allows you to see aperture values from the right side (as opposed to the version for the Actus). The form of the panel avoids interfering with the camera.
If they just put a Fuji GFX mount on on side of their panel then we would have the first kind-of Canon-GFX adapter. Cambo seems to be the most innovative and fastest company in this segment.

Ok I see a few mentions regarding Leica R lenses above, and now I also see a mention of an EF lens to Fuji GFX adaptor from Fotodiox above as well, am I safe to say that my set of Leica R lens that have been converted to EF mount will most likely work on the Fuji GFX with possibilities of needing to crop in on some of the lenses to remove vignetting?

I have a set that has been cine modded and Leitax adaptor converted to EF mount:

It will be very interesting to see how well the 17 and 24m TS-E lenses work.  Too bad there isnt a 35mm.  I don't know if the Schneider 28 or older 35mm PC lenses would hold up well enough compared to just using a tech cam.

The Canon 24 ts-e and the 1.4x TC work well as a 35mm. Not had any problems when I've used that combo. Maybe a little more CA.

Judging by the examples on the Alps site, the TS-e's will cover the sensor easily and should perform well.

Excited to look at the Fuji as soon as I can.

Right. That's assuming you are going to use both sensors uncropped.

If you're going to crop to 4:3 or squarer, the crop factor is 24/33 or 0.727.

If you're going to crop to 3:2 or narrower, the crop factor is 36/44 or 0.818.

Erik,
I think this is a really good point. From Fuji's perspective (and from a Fuji user's perspective), offering a 135 format makes little sense: Barely better than their APS-C offering and lots of tough competition. Especially if you remove the legacy mindset of 135 SLR being the standard. Fuji users love the layout and haptics of the system so it makes some sense to think of this as an upgrade for current Fuji users.

You can look at this two ways: 1) Fuji formats are almost as good as 135 and 54x40. Or 2) Fuji formats are a bit better than m4/3 and 135. Since the size of Fuji's cameras and lenses compare pretty well with #2, their strategy makes sense to me.

Does anyone know if the Fotodiox Nikon adapter will work with the G lenses, that don't have the aperture ring?  From looking at the adapter it seems to have a series of oooooooo markings on the front below an arrow, so not sure if this is a click less aperture arrangement or not.

BTW, I don't believe the Sigma Art 14mm 1.8 is shipping yet, at least in the US.  Wondering how it will handle coma.

I did some tests today with my 35mm lenses. Pretty much all of them could easily cover 44x33. The only ones that could not do it was some of the wide angles like the samyang 14mm. What really amazed me is the sigma 85mm 1.8 ART. It was able to cover 6x6 edge to edge with no problem at infinity. So I am really optimistic about adapting it and lenses like it to the GFX. Sigma 35mm 1.4 can also easily cover the GFX too.

It just demonstrates that the sensor of the GFX isn't that much larger than FX... ;)

Let's hope an AF-adapter Canon EF - Fuji GF is released soon.

Sigma Art lenses covering 44x33mm will offer fast aperture / shallow DOF that was up to now unknown in MF photography:

Sigma Art 35f1.4 equals 29f1.1 (long axis ratio) resp. 25f1.0 (short axis ratio)
Sigma Art 50f1.4 equals 41f1.1 (long axis ratio) resp. 36f1.0 (short axis ratio)
Sigma Art 85f1.4 equals 70f1.1 (long axis ratio) resp. 62f1.0 (short axis ratio)
Sigma Art 135f1.8 equals 110f1.5 (long axis ratio) resp. 98f1.3 (short axis ratio)

(assumed that the Sigma 135 also would cover 44x33mm)

Let's hope an AF-adapter Canon EF - Fuji GF is released soon.

I emailed Cambo and asked if their upcoming Actus version for the GFX would allow the use of their Canon lens board with electronic aperture control. They sent me a very detailled answer. I really like Cambos open way to respond to customer questions and discuss possible future products. Here is what they said about the Actus and Canon lenses:

"The Fujifilm G mount has a focal flange distance (FFD) of 26.7mm, the Canon lens has a FFD of 44.0mm, than you will have a distance 17.3mm left, this is not enough space to construct a front and rear frame including a bellows to achieve tilt, swing and shift movements. So unfortunately within the Actus system it in physically impossible to use Canon lenses on the Fujifilm GFX camera.

Therefore we are thinking about designing an fixed adapter between the GFX camera and Canon lenses, this way the Canon TS-E lenses can be used on the GFX and you have still some tilt/swing and shift options for the TS-E lens itself. "

So when Metabones does not plan to do something for Canon lenses with aperture control - it looks like Cambo might do that. For my TS-Es I even prefer a fixed adapter to the Actus solution. If you want that too: send Cambo an E-Mail and request for such a product.

That would be interesting...especially if the 24 TSE with a 1.4tc could potentially work and be of any decent quality.  I am very curious as to how solid a performer this camera will be with those lenses.  The 17 is great... the 24 II is better than the first...but still had a long way to go.  Then again a 17mm TS on a 44mm sensor... that is wide... with shifts?  Don't think ive seen that before!

Someone should bug Redrock Micro to do a version of their LiveLens EF mount for M43 for the GFX - https://shop.redrockmicro.com/product/livelens-mft-active-lens-mount/

It's just electronic aperture control, but would give immediate usability to a number of lenses.

Would also love to know how this was done and whether the "image circle" you talk about is useable or more just the total image circle that is projected...  There can be quite the difference ;)

I am really interested to know what image circle the GFX lenses project, mainly to see whether Fuji built them with a full frame 645 Sony sensor in mind..

They are reasonable slow after all....

...yes - by setting any aperture on a Nikon body, and by pressing the preview button and simultaneously removing the lens from the body (similar to the electronic Canon lenses).

That's great in the field...you need to carry along a D810 to set the aperture of your Nikon lenses on a GFX... where the lenses will be manual focus only... ;)

Anyone know of an adapter that would allow Phase S-K Blue Ring lenses being used on the GFX? If only MF that is OK for now.
Title: Re: Lenses for the gfx 50s
Post by: Paul2660 on March 03, 2017, 12:11:45 pm
That would be nice, to be able to use the SK blue ring or non Blue ring.  Issue will be Aperture control as non of those lenses have manual aperture control.  The much older MF Mamiya would work with the M645 adapter I keep hearing about. 

Firing the aperture would require an electrical connection I believe like with Metabones and Canon/Sony.  I am sure P1 will not work on a solution, so it would take a 3rd part with knowledge of the electrical pinouts I believe.

Would it make sense to use these heavy and bulky lenses on the Fuji?

Considering that you can pretty much buy the whole Fuji 3 set for the price of a P1 35mm, I would personally invest in Fuji glass. At least that's probably what I will do if I decide to add the GFX to my line up, no intention to use my H lenses on it, although there is a smart adapter with aperture control already available today.

Using the Otus 85mm is much more tempting as that piece of glass is superior to anything available in the MF world IMHO.

Could make sense as a backup body for Phase One users.

Further than that, I also would prefer to trust the Fuji lenses instead of creating some Frankenstein Camera-Lerns combinations.

That depends. If you don't need shift, I would go for the Fuji lenses. Tried the the 63mm f2.8 prime and it is great. I expect the others to be too.
But if you want to use shifts - the SK lenses are designed for the 54x40mm sensor, so that will give you some shift capabilities.

My question is: which of the wider angle full frame 645 lenses can be used? Schneider, Contax, Hasselblad H need electronic aperture controls. They seem to be better than the older mamiya who don't. Does anybody know if the Pentax DFA 25mm f4 (only available in Japan I read) needs electronic aperture control too?

The Fuji adapter for H lenses can control the aperture, H lenses are fully usage except AF.

Actually, you can buy 2 P1 35mm Blue Rings for the Fuji and 3 lenses,  6800 35mm BL  vs  13K for Full Fuji Kit. 

And, if you own one already, no reason not so want to consider using it on the Fuji,  excellent optical lens.  Can't compare it to H glass, but by best I have used from P1 or Mamiya, and equal to the Rodenstock 32mm.

For non shift I was under the assumption my S-K BR lenses also worked on the Phase 44x33 50Mp backs without issue. Who cares about the size if a 150mm/3.5 works then that would be a great FL to have NOW plus one can use the 2x on that lens giving a 300mm. Sure Fuji GF lenses would be best, but if it is to be used as a back-up to a Phase IQ3 then one should have an adapter working with Phase S-K lenses in the bag.

I once owned the last 25/4.0 Pentax lens sold in the US after they stopped production a few years back and it needed electronic aperture control. Pentax says the 28-45 replaced that lens, but I can tell you it did not.

I wonder if the Otus image circle will not create vignetting on the 44x33 sensor? Anyone know.

The P645 SDM lenses have a mechanically controlled aperture. YES you need to select the aperture on the body as there is no ring on the lens. But you can control it on an adapter if it's designed with a control lever. The p645 plate for the Cambo Actus has a lever for this, I've used one, it works fine.

Looking at the Fotodiox adapters their Nikon adapter had a ring for aperture control on the G lenses. As they have announced there will be a P645 adapter, I'd imagine they will do the same thing on that.

Yes, the Combo P645 lens plate can control the aperture on a Pentax 645 lens, but sadly the M645 is for lenses with manual aperture  only.  Good news for the folks with Pentax glass as it's very good if not excellent optically.

I might have to run up a question to combo on the M645 adapter to see if they can make one that does control aperture.

Do the Blue Ring lenses use electronic aperture control Paul?
Not up on how these sorts of lenses are controlled, I imagine it's not to hard for the experts. Cambos canon mount took a while to come out mostly due to them figuring out how to package it  Just a matter of whether there is enough interest to make an electronic adapter. Cambo have got a form factor for the control unit now, so just need the interest, to change the mount and what the micro processor does I guess.

If am not mistaken the lack of aperture ring doesn't mean necessarily an electronic aperture control.

I had the impression in my Mamiya ZD days that the aperture control was mechanical like on the Nikon G lenses that lack an aperture ring also.

Bernard, you are correct, I also believe the Schneiders are non electronic.  I guess the only true electronic are  like the Nikkor PC-E lens and maybe the Canon TS-E lenses.   Hopefully an adapter can be made like the Fotodiox adapter for the Nikkor G lenses.  That adapter does have the ability to set the aperture with a ring.

Hello there are 3 types of nikon lenses:

1) older lenses with aperature ring on the "barrel"

2) newer G lenses with mechanical aperature control -> pic1 -> small Lever -> This could used with adapters like Novoflex

3) newest Nikon lenses with elektronical aperature control e.g. 24-70mmVR (like the newer canon lenses) ->pic2 -> No available solution with adapters now

thanks for the clarification and the pics.  I haven't purchased a Nikkor in a while so I missed out on option 3.  All of mine are the G style, so hopefully the adapter will work on them. 

Can't tell what the Schneiders are, they do have pinouts inside the flange.

Hi Paul,
here is a picture of the Schneider 55mm LS. It has only electronic contacts. No mechanical. The only mechanical "thing" is the focus "screw" on every phase lens (hidden under the arrow - OK not a good picture..  :-) )

This means not a good way for adapters "Phase to Fuji" :-(
