Title: Question on Zeiss Makro-Planar 100mm f2.0 ZF
Post by: BernardLanguillier on January 08, 2009, 04:34:19 pm
Dear all,

For those of you owning the Zeiss Makro-Planar 100mm f2.0 ZF, I am looking for data on the location of the entrance pupil point of this lens is located relative to the mount or sensor plane.

I am interested in this lens for pano applications, but will probably not have the chance to test it in the coming weeks. The position of the entrance pupil point will impact the interest of the lens in terms of pano head stability.

Thank you.

Cheers,
Bernard

Hope you don't mind me piggybacking your thread. In addition to entrance pupil info, I'd be curious about user impressions of this lens for landscape (ie at or near infinity, rather then closeup/macro).  I know this lens is supposed to have stunning performance based on many of the user-reviews I've read, but does that hold up at longer distances or just closeup/macro?

Lloyd Chambers- didlloyd.com - has a comparison of the zeiss and canon 100m on his subscription site (which is probably worthwile if you're considering a zeiss lens as there are a few surprises) - in short, he loves it, but the comparison was on a 1dIII and the 100m turned out to be "off" (which seems a bit unusuall for this lens) so not as definitive as to convince me to pay several times the price of my excellent 100M for manual focus

Bernard, can't you just buy one with return privilege and find the entrance pupil?  I've resigned myself to testing canon lenses and buying multiple copies as required (although i suspect most of the issues are front/back focus which should be greatly reduced with new cameras with focus adjustment - still requiring investment of the user's time)

Here's a review on it: http://slrlensreview.com/content/view/287/96/ (http://slrlensreview.com/content/view/287/96/)

I have seen some great reviews on this lens, and was very interested myself, until I found out that the lens doesn't even offer true 1:1 macro focusing (only 1:2). For a company to charge 3x the price of the Canon 100mm macro, and yet not even really have a macro lens, is absurd. The lens does not even have autofocus either. I understand that autofocus is not generally used in macro work, but here again the Zeiss lens can't use this as an excuse because it isn't even a true macro, since it is incapable of providing true 1:1.

This means the Zeiss "macro" lens is really nothing but a portrait lens ... that doesn't have autofocus ... but that has the biggest price tag in the segment.

Zeiss may offer great build quality, and great optics, with this lens, but (to me) they simply fall way short by not offering some of the most basic elements in their product, and then they have the audacity to charge twice the price of a Nikon 105mm (with both AF and VR, as well as true 1:1) and 3x the price of a Canon 100mm (with AF and true 1:1).

I think the Zeiss lens is a ripoff, ultimately, and that both the Canon and Nikon 100mm lenses give a person everything they could want in a 100mm macro, at decent prices ($444 and $700, respectively) rather than coming up short in too many areas for a ripoff price ($1500).

I know this doesn't answer your question, and I apologize for that, but I have been looking at macro lenses for a long time and really couldn't believe at what a ripoff the Zeiss lens is, all things considered.

I own this lens and it is a wonderful lens that is razor sharp with amazing bokeh.  It also handles beautifully.  The only other lens I've owned in a similar league is the 85L II.  The Zeiss has much closer focusing and is less of a beast than the 85L.  There are a couple shots with it here from the D3x:  www.pbase.com/cecelia/inbox

There is nothing absurd about this lens.  

I hope someone has used it for panos, because I haven't yet and would appreciate the entrance pupil info too.

Thanks,
Cecelia

Not everyone needs 1:1 repro capability in macro lenses. In fact I would venture to guess that most macro users rarely use a lens at larger then 1:2 repro ratio. BTW ALL manual focusing Nikon Micro lenses (a range which includes some legendary ones) had a max. repro ratio of 1:2. Max repro ratio is only one of the characteristics of a macro lens. Flatness of field and optical corrections for near range focusing are the others. BTW, attaching a simple extension tube will bring the Zeiss' repro ratio up to 1:1 easily without loss of any electrical functionality (since it has none). And also BTW ,this lens is a full stop faster than the commoner macro lenses some people like to compare it with...plus it seems not to loose its qualities at long distance shooting, something which cannot be said for all macro lenses.

For me, this is a fine multi-purpose lens which seems it can deal with a multitude of subjects, not only close-up shooting.

There are some people who can appreciate great optics when they see some. The value for money proposition of any product has nothing to do with its ultimate quality and furthermore its value proposition depends on one's criteria. For some, the Coastal 60mm f4.0 MF lens at $4.500 may be a rip-off. For me its just a highly priced excellent product. No high quality product deserves the definition of a rip-off however one perceives its value for money proposition. I reserve this term for highly priced low quality products.

I personally can not justify the cost of the lens but that does not mean I wouldn't love to own one.

Interesting that the detractors of this lens haven't tried it, but the poeple who own one think very highly of it. Of course if your priority is AF or VR then this isn't the lens for but if you're after optical quality, well its in a league of its own. I don't see how AF and VR equate to quality and value when you look at all the cheap and nasty consumer products that come with it, it sure can't cost that much.

Apologies to OP, I know these conversations don't answer your question but to be honest I have no clue were to even begin to respond to you.

I'm sorry, I didn't mean to step on anyone's toes, nor did I mean to imply that the Zeiss 100mm "macro" didn't have stellar optics. What I felt was absurd was for a company to charge 3x the price of its competitors for a "macro" lens that doesn't even have true 1:1 macro capabilities.

You raise some good points, Nikos, so perhaps the word "ripoff" was a bit strong. But to charge 3x the price the lens should offer 3x "something better" in return for the money. Are the optics three-times better than the Canon/Nikon equivalents ... or are the optics only marginally better ... with no AF, no VR, and not even true 1:1 macro capability? Perhaps it's not a ripoff, but the value of this lens doesn't seem 3x as great in proportion to its 3x greater price tag.

Both the Canon and Nikon 100mm/105mm are considered stellar choices optically themselves, so although the Zeiss may be so good optically that it is a bit better still, even if it was listed at the same price as the Nikon 100 mm, it would still be a pick-em, because the Zeiss' marginal edge in optics is hamstrung by its deficiency in magnification, AF, and VR.

That is just my opinion. I do understand that some people would believe differently based on different needs.

You're not stepping on any toes Jack, this is all just good fun and friendly chit chat on a slow Saturday, I guess with members coming from all over the place and of different cultures sometimes the tone of one's conversation could be misinterpreted as aggressive or offended anyway, back to the subject at hand...

For one the Zeiss is only twice more expensive than the Nikkor not 3x, and yes the two lenses are very different. Personally I find the Nikon lens over priced, just don't like the look or its rendering and Zeiss underpriced in comparison, but like everything else value and beauty is in the eye of the beholder. Zeiss is about the optics and build quality, electronics don't cost any money today in a market where you can pick up a fairly decent AF zoom lens for less than 60 bucks (http://www.bhphotovideo.com/c/product/97388-REG/Tamron_AF77N700_Zoom_W_A_Telephoto_AF_28_80mm.html), I don't see the big deal about 1:1 either, nor do I need it.

I'll add that these debates are all in good fun, and as has been said thousands of times before, the brain behind the camera is far more important than the camera.   The difference between excellent and "the best" is often subtle and comes at great price.  Value is not a linear curve, it is a hockey stick curve.  Look at cars, clothing, jewelry, etc...the very best always costs a lot more than products that are excellent, and some people are willing to pay for that little bit extra.  As I said earlier, in my experience, the 85L and the 100ZF are special lenses that have a quality about them that is different than most other lenses.  The 85L is far more expensive than the 85 1.8, and in objective tests the 85 1.8 looks very compelling...so is the 85L worth all that extra money?  Yes to some, and no to many others.

Hi Bernard
With the ZF 100mm, I have to move the D3x back by exactly 45mm on my Manfrotto 454 sliding plate to have no visible displacement between near and far objects (using live view with maximum magnification).
I have only just tried this setup to be able to answer your question, because so far with that combination I actually just did some handheld stitches on infinity.
Having seen some of your stitched images, I know you would use it for quite close things as well, so the 45mm should get you there.

The ZF 100mm is a great lens, it's actually the best (resolutionwise) I own for the D3x, even in the extreme corners.
What's been pointed out in this thread about the ZF 100mm not having autofocus nor VR simply doesn't matter the way I use this particular lens:
For me, it's well worth the money.

Hope that helps.

Jost

To reiterate, "macro" does not mean or imply that a lens magnifies 1:1, which is a rather new phenomenon in the industry. Back in my retail days, '70s and early '80s, all the manufacturer macros were 1:2 with an extension tube used for 1:1. The only 1:1 lens was from Vivitar or other branded version from the same maker. "Macro" was a designation used for flat field lenses specifically designed of close focus and copy work(industry term, not an opinion). Most did not do as well at infinity and were rather slow compared to their curved field counterparts. Unfortunately the term became corrupted when it started being used for zooms with close focus capabilities and soon became used for all close focusing devices.

You raise some good points, Nikos, so perhaps the word "ripoff" was a bit strong. But to charge 3x the price the lens should offer 3x "something better" in return for the money.

Perhaps it's not a ripoff, but the value of this lens doesn't seem 3x as great in proportion to its 3x greater price tag.

Ripoff implies theft, so it's more than "a bit strong", especially when constantly repeated. I worked for three years in a camera shop in Westwood Village, a tony shopping town that serves UCLA. After hammering us as "ripoffs" for being $20.00 more than Adrays on equipment with a 10% margin, people would go next door and drop $300 on a pair of shoes with a 100% or more markup without batting an eye.

Both the Canon and Nikon 100mm/105mm are considered stellar choices optically themselves, so although the Zeiss may be so good optically that it is a bit better still, even if it was listed at the same price as the Nikon 100 mm, it would still be a pick-em, because the Zeiss' marginal edge in optics is hamstrung by its deficiency in magnification, AF, and VR.

It would be interesting to see if modern macro lenses from Canon/Nikon are true flat field lenses or some sort of hybrid created in response to people insisting on using them for purposes outside of the original design criteria. They certainly seem to be engineered more like conventional lenses. Could be the Zeiss is actually the true macro. In any case, if comparing macro lenses, do it under conditions they are designed for. If the intent is not for critical close-up or copy work, than maybe other equipment would be more appropriate. I've got the Canon 135/2 L, which is a phenomenal lens that also does bugs very well.

That is just my opinion. I do understand that some people would believe differently based on different needs.

Likewise, but for the definition of a macro lens.

LOL, well, we have something in common then: I graduated from UCLA, and lived in Westwood for 3 years back in the late 1980s, but instead of working at a camera shop I was a bouncer at a little nightclub back then called Baxter's

But your point is well taken.

Very interesting. Maybe the Zeiss is the true macro after all,. Thanks again for taking the time to point all of this out to me and to give me an understanding of the word "macro" as it applies to lenses. From my perspective, I didn't see the value of the Zeiss over a Canon or Nikon, as I was looking for true 1:1. You said 1:1 is a new concept to macro, so maybe this is the newer definition of macro, I don't know. What I do know is sometime down the road this year I am going to get the MP-E 65mm f/2.8 which has 5:1 capability, and I am buying this lens precisely because extreme close-up shots are very important to me and what I do. The MP-E 65mm f/2.8 is called a "macro only" lens, as it cannot in any way focus to infinity at all. I am not sure if its optical "flatness" makes it designated as macro only, or if in fact its intensive magnification is why (or maybe both reasons apply).

Anyway, again, I do see the value of the kind of extreme resolution the Zeiss offers to some. There are clearly people who are willing and able to shell out the extra $$ for this difference; yet there are other people who coin phrases like "mouse nuts" who aren't willing to pay 2-3x the price of the competition for that kind of negligible difference. What would really be interesting and germain to "true value" would be to see how many saleable macro shots have been taken through which lenses ... if there was a way to quantify such things ... and based on these statistice see which lenses have produced more photos that have sold for the most total money, as well as the most money-per-image. This would be another way to find the bottom line value on things, I'd say.

Thanks,


I use the ZF 100mm only outdoors (but a lot) with various distance settings, it's focal lengths and handling just seems to fit my shooting style.
I find the quality of the files this lens produces simply outstanding, having used it on the D3 for over a year and now with the D3x since December.
Compared to other lenses, it produces sharp images even at f2 all the way into the corners, vignetting can easily be removed.
Contrast and resolution improve slightly by stopping down, maximum is reached at f5,6 and is maintained very well to f11. I even use it at f16 if dephts of field is absolutely required, never mind the diffraction effects, which start to show at f11 already.
Because it's distorsion free, I use it for stitched images quite a lot, even handheld and on infinity.
For macro work, the max. 1:2 suits me well enough, I haven't done much testing comparing it with other lenses at close up distance settings.
For reproduction work (indoors) I have been using the Micro Nikkor 2,8/60mm D with great success and have now switched to the 60mm AFS, which suits my other needs very well.
It's shorter focal lenghts is of advantage since I have to reproduce an artists work on a regular base. Her paintings vary from 12"x12" to 40"x 50".
But outdoors, the free working distance of the 60mm AFS is often too small for certain closeups.

I also use the ZF 2/28mm which is a fine lens but it shows quite extreme curvature of field.
The ZF 100 doesn't show any sign of this.

I am a subscriber to diglloyd (www.diglloyd.com) , who has a comprehensive review of the whole ZF range: Highly recommended.
Some of the ZF lenses have also been tested by SLRgear (www.slrgear.com) and Photozone (www.photozone.de).

Using the ZF lenses is kind of old style, but they complement zoom lenses very well.
I use the 14-24mm, 24-70mm, 70-300mm VR by the way and am looking forward to a new version of the 80-400mm with AFS, VRII and Nanocoating very much.
I hope Nikon will introduce such a lens this year, it would be a of great use for outdoor and travel photography.
And together with my ZF 100mm, it would make a great combination.....

Hope that helps.

All the best

Jost

Obviously you can get to 1:1 and beyond with the 100mm ZF. You put extension tubes between the camera and lens.

And by the way at 1:1 the 100mm is far superior to the current Nikon 105mm AF-S VR Micro in optical terms. I don't think the Zeiss is overpriced.

Having a solid manual focus control is an asset in a lens for close-up work. Too many autofocus lenses are compromised in this respect, and some manual focus lenses like the 85 PC-E have too fast turn in the ring.

The 100mm ZF is the best and most consistently performing lens I've ever used. If anything it makes me a bit underwhelmed by lenses available at other focal lengths. For portraits I would use other lenses which produce less contrasty images and there are some lenses that work better in night shots but for image quality under normal nature photography situations there is no better than the 100mm IMO.

Hello Jost,

Thanks a lot for your help on this, this is very good news as it looks like the entrance pupil is located a the best possible position for stable shooting on a pano head.

I have actually ordered the lens and should have it in a few days.

Yes, I agree 100% with you on this.

Life view makes it easy to reach perfect focus with a MF lens anyway.

Considering so many people talked about the old days of "true macro," I found it quite interesting that years ago the ORIGINAL Zeiss (Contax) 100mm macro in fact did have true 1:1 macro capability, but that only the "new" Zeiss does not. Some of you fellas talking about what it means to be "the best" might find this part of the review interesting:

"Naturally, one of the major interesting aspects of Carl Zeiss Makro Planar T* 100mm f/2 ZF is its macro capabilities. Compared to its previous Contax version, the Carl Zeiss Makro Planar T* 100mm f/2.8, the new lens does not offer life-size macro - Zeiss designers decided that 1:2 macro should suffice in this case. Is this really a problem? Depends whom you ask, but it does seem like a step back, especially when we take into consideration that Zeiss does not currently offer a 1:1 converter (unlike its main rival Leica)."

http://slrlensreview.com/content/view/287/96/ (http://slrlensreview.com/content/view/287/96/)

Thus, not only does the Leica offer a 1:1 converter (while Zeiss does not), but it compares quite favorably, resolution-wise to the Zeiss. So a couple conclusions may be drawn (1) in "the old days" Zeiss (Contax) was in fact 1:1, so the newer version is thus a diminished version, and (2) the newer version isn't necessarily even the best $1500 macro available, for those who want to spend that kind of money. The current Leica 100mm macro affords very similar optics and build quality as well as an option to obtain true 1:1 macro capability.

The current street price of the Leica, which is a slower f2.8 lens and also only goes to 1:2 without an optional adapter - it is $4495 at B&H. The adapter is $569.95...

Ouchie-wawa!!

The 1:1 adapter cost more than my whole freakin 100mm macro lens

Somebody's proud of their equipment  

I guess the Zeiss is a steal compared to that 8^)

I had the Leica macro back in the film days with my R4/R5 or whatever it was - spent quite a bit of time shooting macros and I never used the lifesize adapter a single time - just did not need it. I have the Zeiss 100 macro now and don't feel the need for 1:1 either. I've got a 200 macro that does go 1:1 but never get that close. For those who do want really close macros the Canon 65mm micro is the way to go - it will do 1x - 5x lifesize and is a really good lens. (I also had a Contax RTS III and their 100mm macro too.)

Hey Jeff, I can second what Josh has said - I also use this lens for stitching with the D3X at or close to infinity - it is a sweet lens that lives up to the rep it has gained in its short life. I've shot with Zeiss on and off over the past 34 years and have always felt - and continue to do so - that there is something special about the Zeiss lenses. I like what folks are saying these days, that they "draw" differently, is a good way to describe it. Most folks don't really care about such things, and that is fine with me - leaves more lenses on the shelf for me to buy when I need one!

Don't know about you, but for me it is in the very same class in terms of sharpness/detail as the 22MP MFDB.

One hand held pano made from 12 D3x images (resulting image is only 80MP because of excessive overlap between the frames):

Thanks for the full-resolution sample Bernard, impressive indeed. I think this thread is going to cost me $1500.

Hi,

One could consider a:

Contax N Carl Zeiss Makro-Sonnar T 100mm 2.8 modified by http://en.conurus.com/ (http://en.conurus.com/) to work in AF with Canon EF Mount. You have the best of both worlds: AF and 1:1 Macro and some might say a more recent technology.

I am still getting use to it. The colors are more life like and not oversaturated.  Did I mention sharpness far and beyond what I was expecting?

The results are better than the Canon 180mm and the 100mm and surpasses the Nikon 105mm. Yes, I did own these lens. In Macro, I use the Canon Angle Viewer since the DOF is razor thin.

You can find one on eBay and have it converted or purchase one for about 1500$. You can still have it serviced by Contax Japan.

You can read a review here: http://www.pebbleplace.com/Personal/Contax_100N_Makro.html (http://www.pebbleplace.com/Personal/Contax_100N_Makro.html)

Sorry, my intentions are not to divert the conversation but rather attract your attention to an alternative...

Thanks for this information. It seems like Bernard has already found his own personal Heaven and received the info he was looking for, so your diversion of topic is a welcome adjunct to the main topic. I think, as always, it boils down to the right tool for the right job. It sounds like Bernard found the perfect lens for his purposes. I did not mean to hijack this thread either, but to point out some useful information whereby some might come to realize that the Zeiss 100 macro, while considered the absolute cream of the crop in many ways, was not the perfect macro lens for certain macro functions.

As you mentioned, and I mentioned previously, the older Contax version is actually the all-around better lens, but what you just taught me was that it was AF too (I did not know this!), and that it might still be available second-hand. For documentation purposes, an AF lens on a 100 mm macro is as essential as true 1:1 magnification. One of my interests is obtaining photographic documentation of butterfly species in my area, and reporting my findings to www.ButterfliesAndMoths.org , who base much of there "range map" knowledge of butterfly geography on the submissions of registered contributors, who keep an eye (and a camera) out to record any new species they see. So while a manual focus lens of the rare quality of the Zeiss may be great for a photographer with a tripod, who has all the time in the world to compose the perfect shot, such manual efforts not only can mean a rare opportunity can be lost in the field, but that the very manual rotation of the lens creates extra movement that itself can scare-away specimens. In fact, renowned lepidopterist (butterfly expert) Dr. Jeffrey Glassberg has this to say about the perfect equipment for butterfly photography:

"(Dr. Glassberg) strongly recommends chosing a camera body that has automatic focusing and automatic shutter speed and aperture setting programs ... with manual focus/settings the requirement that your other hand must turn the barrel of the lens to focus it increases the chances of the butterfly detecting the movement and flying off ... to get consistently good shots you should use a 100mm macro lens. Make sure that you are getting a true macro lens, one that at closest range results in a life-size (1:1) image. Many lenses listed as 'macro' lenses ... do not have this feature. Without a true macro lens the butterflies will generally look small in your pictures; with such a lens the butterflies will fill the frame."

Dr. Glassberg is author to the well-known "Butterflies Through Binoculars" 3-book series, where he has photographed every species of butterfly in North America, and probably has more field experience doing so than any photographer on earth. The point of this digression is, although the Zeiss' stellar optics may be perfect for the photographer who has all the time in the world to sit there and tinker with his camera to get it perfect, it's fully-manual requirements cause a time-robbing delay in getting crucial nature shots at all, on top of which the very action of moving and rotating the lens is itself a threat to scaring-off the subject.

Thus while the Zeiss may be an unsurpassed tool for one man's job, it is a cumbersome and and inappropriate tool for another's job (both in its lack of AF as well as in its not offering true 1:1). What good is the extra resolution of a lens if you miss the shot altogether—or, even if you get the shot, if it's not a truly close 1:1 capture?

Many of the readers may not care about these matters, for 'their' purposes, and that is great. But I know when I was researching 100mm macros for my purposes, that these lacking features in the Zeiss were MAJOR drawbacks to its usefulness in the field, and so for those viewers who also might not have been aware of these particular limitations to the Zeiss, I posted these limitations on this thread, that were also considered major limitations by SLRLensReview.

So thank you for posting that link, Pratic. I did not really take the idea of getting an older lens all that seriously, but the fact that not only is the elder Contax version a true 1:1—but that it is also an AF—is wonderful to hear. I think somewhere down the road I will try to acquire this lens for myself, as it truly does appear to be the best of all possible worlds: resolution, AF, and true 1:1 macro.

Those are not the same lenses; you're talking of an F1.2 lens, the review is of an F2.8 lens (which admittedly contains a confusing tidbit about an F-stop scale of F1.4 to F22 while the image clearly shows a maximum of 2.8).

Are you sure you didn't accidentally typo the name of the lens?

Oups! Please forgive me. Yes, it is a F2.8 to F22 lens and not an F1.2. I had my mind on another lens. I must point out that the autofocus on this lens is a bit noisy and relatively slow to focus.

With the ZF 100mm, I have to move the D3x back by exactly 45mm on my Manfrotto 454 sliding plate to have no visible displacement between near and far objects (using live view with maximum magnification).

The entrance pupil can be determined by viewing the lens from the front and measuring the apparent position of the diaphram from the sensor plane.  The hard part is figuring out how to measure it accurately

Can you tell if the entrance pupil moves when you change focus distance?  My 70-300mm zoom's entrance pupil at 300mm changes from the center of the lens to 18+ inches behind the sensor when changing the focus from infinity to it's closest focus distance.  Obviously not a pano capable lens

Thanks for explaining this--it makes more sense than trying to determine the point experimentally!  Why wouldn't the location of the aperture be the location where you'd want to pivot? In other words, rather than estimate from looking at the lens, why not look at the lens-design diagram or try to measure with a ruler and place that location over the pivot point?  Shouldn't the aperture always be at the a nodal point?

Thanks,
Cecelia

I've just checked 4 lens diagrams (3 Nikkors and the ZF 100 f2 makro) and am 0/4 on seeing where the diaphram is.  I guess we have to guess...which seems crazy.

LOL, well, we have something in common then: I graduated from UCLA, and lived in Westwood for 3 years back in the late 1980s, but instead of working at a camera shop I was a bouncer at a little nightclub back then called Baxter's

Jack

Baxter's eh. My, what a small world. Was Campus Camera still going when you were there?

Greetings all -

Just to clarify the macro discussion, I recently had a chance to talk to a Canon tech rep and he verified that the Canon Macro's were flat field lenses. Think it would be safe to say this is probably true with the other manufacturers as well.

Considering that the micro lenses on most current camera image sensors need the light to fall on them in as close to a perpendicular path as possible, it may be that modern lens design is heading towards flat field across the board by default.

It's not the physical location of the diaphram, it's the apparent location. The nodal point is not the same as the entrance pupil, but a lot of people mistakenly call it that.   Most modern zooms move the entrance pupil when focusing and zooming, which makes it rather hard to use them accurately for panos.  I don't know if modern prime lens do the same.  That's why I was asking about how the Zeiss behaved.
