Very exciting Michael! I need to get an adapter and try out my lenses at the local shop demo Z7. I still prefer the rangefinder for my 18mm-50mm lenses for focusing, but it would be nicer to frame the 18mm, 25mm, and 85mm on the Z7 with an EVF.

Ahh, thanks. So it does the same as The Sony bodies; you set the FL, no EXIF is reported but IBIS works for that FL ...

There is a roundabout way to test as well. Put in a wildly wrong FL, eg a WA FL for a tele lens, or a tele FL for a WA lens. If IBIS is trying to steady the lens with the wrong FL you'll see an image in the VF that is jerking around all over the place.
I may or may not have done this ...


It does a bit more than the Sony...it records the focal length in EXIF (as well as the maximum aperture). This gives a reasonable starting point to actually identifying the lens used in a particular shot. Sony gives you nothing.

Thank you very much for the test images, this is very exciting news! Now I all of a sudden have hope for my 24/3.8 Elmar, it’s such an excellent lens so I would be really thrilled if it played well with the Z7. My adapter will not arrive for a while so I have to wait before testing my set of M lenses.

Too bad about the missing EXIF data and no Ibis but the important thing is that the Z7 looks like a good platform for M glas.


I bet it will be good. I really hope Nikon can unlock the EXIF and focus confirmation for adapted lens. These two are another important weapon to make Z7 even better.

Thank you so very much Michael! The testing you have done is a lot of work and I am really pleased about the 50 Lux I have always been a 50mm shooter and this really excites me. The 50 Lux is just an amazing lens for its size/weight and rendering... wow. I had spent 4 weeks originally testing the 50 Lux on the A7r and then the Kolari modified sensor and I was never happy.

I now would love to get the M 50 Noct f/1.0 Mandler again and test on the Z7


Yes, 50lux is still my favorite 50mm as a total package for real day to day base use. It is the one bridge the old school rendering with modern f1.4 sharpness at center, a wonderful tool. A smaller version of your loved 58G with better center sharpness, a little less smooth bokeh but don’t forget it has better color with less CA. if you see my images above carefully, with the same sharpness setting, its center looks over sharpened, which means it has very high performance optics without need help from sharpening as much.
I would love to get that Noct, but for the same price I am waiting for Nikon one

Thanks so much for these tests Michael.
Can you clarify something about the IBIS please? You wrote that it does not work for the target FL even though you can input the focal length. By that do you mean it will not work at all, or it will work but not optimized for the FL you input?
Either way I'd hope Nikon could fix that with a FW update, otherwise I see no point in allowing input of the FL.

Thanks

Mike



Hi, Mike, I am glad it helps. After read your question and CVickery’s answer. I think I need be more clear about my description.
1. For any Nikon F mount without CPU either ZF, Leitaxed R through FTZ, You can manually input Lens focal and max aperture. The EXIF will not record the shooting aperture you had but you will know which lens you used as the lens information will be in your EXIF data. LR will be able to found the lens by entering focal length.
2. For any Nikon ZF.2 OTUS with CPU etc, you don’t need do anything that EXIF will automatically be generated. However, there is no focus confirmation for them.
3. For G, E type of auto lens, as long as you are in AF-S single and if you put lens in manual focus, it will have focus confirmation with all the EXIF.
4. For Leica M glass with non CPU adapter. You can input lens focal length and max aperture. But no EXIF data will be recorded and you don’t which lens you were using and what aperture you had. LR will show them all as unknown lens with 00mm/f00
Now, for item 1~3, I am pretty sure IBIS will work. For Item#4, I am unsure and it is hard to qualify. I can say that EVF is still stabilized, but does it optimized for focal length? or do it apply Non-CPU lens data I entered? Or do it even need focal length information for IBIS to work? I don’t know. And I personally don’t want find that out. It will take a lot of time to do controlled test.

Thanks Michael for the test. I think the extreme corner of SEM still looks a bit poor but honestly, I don't remember how the corner of SEM supposed to look like on a M body anymore but I understand that it supposed to be sharp all the way into the corner with no field curvature on M body, no? I do have 24/3.8 that I am curious to see how it would match Z7. I have been waiting patiently for my local dealer to get in a Kipon adapter which I hope will be very soon otherwise I might break

I think it might be crisper a little bit on M, but keep in mind I never test this lens on 45M pixel. From 24M to 45M is huge difference. It performs way better than stock A7RII.
I personally give its performance a pass. It shows no smear and funky stuff at corner. That is all I need for landscape as long as corner show decent fidelity without too much distracting. I don’t do much pixel PP even my test show otherwise I usually need spend some effort to understand the lens behavior to better use it.
BTW, the adapter doesn’t give me full confidence that it will give best test condition.

These look great.

I was wondering if you had you used the M glass on the SL? If so... how does the Z7 compare optically.

I have been thrilled with the performance of the M glass on the SL, and the SL glass as you know is off the charts.

Don



Hi, Don, I did, I use M and R glass on multiple occasion at Leica Store SF. I’d say Z7 is at least as good as SL at pixel level. That means I don’t need even downsize 45M file to compare SL. If you consider pixel difference here, Z7 will be miles better. I believe the M glass performance here with Z7 will give better IQ even than M9/M240/M10. This is totally unexpected to me. Even I feel Nikon’s sensor has thinner stack before, but I don’t realize this much.
As you aware, SL glasses are all top class, it need SL2 to make them really shine. 24M is enough for almost all our need if not for print large. However, this is pure gear talk here

See my previous reply. Z7 will not record lens information. And LR will not know which lenses used. I spent quite a bit time to figure this out. I thought there is must some software bug that some setting I did removed this information. I hope Nikon can give us feature back but it might be just a wish. They did enough for me TBH.

Thanks, I definitely didn’t see VF problem. That is a nice information to know. But see my previous reply, we don’t know how Nikon implement IBIS and I don’t know if camera take that info at all. I am sure Nikon’s IBIS is different than Sony’s even on paper, Nikon might be less effective with less stop spec, Z7 is the first one I used haven’t show IBIS ill effect so far.

That's interesting Michael. My Shoten adapter is somewhere between China and here so I can only adapt lenses via the FTZ adapter. This would seem to mean that the focal length is only included if the body sees the FTZ adapter attached...an unfortunate choice IMO.

Thanks very much for that additional information Michael.

If you have a manual tele lens you could try the test I mentioned above, or perhaps just input 10mm on a 50mm lens something like 100mm or so on the 15mm VC. You will see quickly if the body is trying to stabilize the wrong FL with a very jerky view in the finder. If it does this then we'll know the camera is honoring the input.

I will give it a try and report back later.

Here are a few images with 50mm Summilux, all WO. no lens profile or CA remove or any local process. batch process.

Depend on mood I want to achieve, one day I can have a photo walk with 35VC, 50lux and 90APO. Another day with 35PRe-ASPH, 50cron rigid and 75lux. Z7 have very nice build quality, you just feel the density and quality in hand. It hold M glass better than stock M. (So nowdays, I always use grip on M240P.)

You will forget initial premium price quickly once you start use it and enjoy the process. Anything good is not free in life. It will last as many years as you want if you are not just chasing the latest technology. (guity here) In this regard, It is very similar to D850 for me, it largely made the core system right that focused on shooting and operating experience from photographer POV. It has some flaws and deficient spec in some area compare to competitor, but none of them essential for me and many others who care IQ and shooting experience than action.

TBH, other than better AF-C for tracking, and next generation sensor tech improvement for read out speed and even better DR, I don't expect meaningful upgrade for foreseeable future. It IS that good.

Exactly how the A7r should have worked in December, 2013!

Looks absolutely gorgeous, Michael. I expect this thread to draw many more views, now.

I remember the initial hype with the A7r with the M mount lenses only to be disappointed.


No Kidding. Drove me to Leica body!

There was huge furor in lead up as we all took sides on what would happen. Since the Nikon Z7 coverglass is really not unusual, and it was not the thinnest coverglass made by Canikon, who often used exotic formulas for those giant FF bodies 1DX or what ever, I get the models mixed up, was it really naive to hope Sony would give us something similar?

Interviews with the young design team made it clear they had taken a thick route, which I think may have had alot to do with paranioa about lens sales. If the cover glass had been 1.1 would Sony lenses have been so critical?

Think about the endless search for a nice 35 on the A7 series, which is still unsatisfying. CV 35/1.4, an M mount, is maybe the best? Wow. Now shoe is on other foot.

Basically no Canon or Nikon lens did quite as well with the sony as on the native bodies for that simple reason, as tests and the glass in the path articles at Lenrentals showed us. Since one of my main bodies is a stock A7r2, I really feel it myself. You don't know exactly what you will get, and the backgrounds are more effected than what is in focus.

Your sale of 75 Lux dropped my jaw and emphasised the point. Not a wide angle lens. So the effects of thick coverglass are multiple. The M240 had a similar, though far less dramatic issue. Lenses like the 28 cron and 50 Lux were beyond impressive on the M9. The M240 was a bland, cold slate in comparison to both of those lenses. Yes, editing could recover a lot of "the look", and of course the 240 is better than M9 in many situations.

But what is really hilarious is how Canikon have decided to make bigger FF ML lenses than Sony! The fundamental Barnack notion, make it tiny and great, pursued like a religion by Mandler, is lost on these silly corporations, so insulated from real world shooting.

The big three ( I include Sony) are tripping over themselves at the salad bar. Nobody can even get the basics every pro knows they like in a single body. Only Canon has a flippy screen? But Canon cannot shoot 4k full frame? Or make an Ibis? They don't get it. They are navel gazing.

What shocks me past all is the form factor. OK when you shoot 35mm film you need a certain body shape. The Nex-5 started to hack away at the form, but has been let go, basically. In 2018, I would start with anatomy. What is the most natural way to support a lens with hand and wrist? Why is every option dumped into one imperfect form? There is still no organic digital FF camera design. Nobody in 2018 has though of a modular system? Imagine a sensor body which can plug into the options a shooter wants based on the mission. Indoors or out? Film or video? Like a scientific instrument might be designed.

One place to marvel at the pace of change is youtube, where Steve Huff and Kai have had to become videographers, and there is new giant crowd of experts, who are seperating themselves with presentation, and pushing video with it's seperate set of problems into alot of laps, overtly or covertly.

At the salad bar of technical options are all the goodies. High ISO, IBIS, Pixel Shift, 4k 10 bit, Log options wth dual ISO, flippy screens, continous AF at a high level, custom buttons, batteries etc etc. I just wish Oscar Barnack was around to pick out the proper bits and put them in something easy to take on a hike.

Anyway I love to see what this Nikon can do, and finally we have one of our own, Michael, who knows what glass belongs on it

Now, Michael, can we see what the Z7 looks like with M lenses? Or did I miss that post?

The complexity of the glass cover thickness affects so many optical parameters that I just gave up and kept with native lenses for the most part. I suspect the Z7 with the 1.1 mm cover will also improve other third party adapted lenses

Great to see some excellent tests of M lenses on the Z7, especially the Lux 50 ASPH, certainly among my favorite 50's. Having done extensive testing myself on Sony bodies, I believe we are having a similar issue here. Not that it's unexpected. For now, I'm looking forward to the release of that new Noct and the 50/1.2. I'm really hoping Nikon would compromise that 50/1.2 a bit for a smaller size/weight than the Canon RF 50/1.2, something along the line of the current 58/1.4.

@zhangyue

You make a good argument to dump the SL and get a Z7

I actually sold all of my SL glass except the 75 SL. I had the 24-90, 50, 75, 90 and 90-280.

Kept the M stuff, 50 0.95, 50 APO and 10 Voigt.

I love the IQ of the SL... especially with the 75.

Think I'm staying put with the SL for now... I actually just bought a Novoflex adapter to use my MF Nikon glass on the SL. Will see what the SL2 brings to the table.

All first world fun problems...

Michael,

Thanks for the samples with the M glass. These looks pretty comparable in terms of performance with what you get with these lenses on the SL. It isn't quite as good as the performance on an M, but the central and even mid frame is awfully good wide open and the corners nicely sharpen up by f/5.6. I don't think you would have to convert this camera to use these M lenses--maybe older ones designed for film but not these. Too bad about how they treat entering M glass characteristics. The Fuji GFX does much better. You can specify up to 6 lenses in a list by focal length and widest aperture, then when shooting you just select the one you are using from the list and the focal length and aperture are included in the EXIF data. You don't get the aperture you used for the shot, but everything else is there and since I never carry more than six lenses I just make sure the list has the lenses I am taking before I go out.

Yes, I tested it by input 800mm by using 50mm lens, I can clearly see the effect as you described. So yes, the input information indeed get carry over to body for IBIS. Thanks for the tip.

You might be right that 50lux is still better with M body. I am sure Z7 is better than A7 series but I may not be able to back up my claim Z7 is better than M with adapting M glass. see my reply later.

Don't worry about whatever gears introduced as long as you are happy with what you have. There will be always newer and better gear from somewhere. SL is a awesome platform for both M and SL glass.

I agree with what you said. I think Z7 might have similar performance as SL, but not upto M level.

What Fuji GFX does is the same as Nikon DSLR and also F mount lens through FTZ adapter on Z7. It should be the way to do. I am surprised Nikon omit that. Hope it can offer some firmware update.

Yesterday, I spent all the time upload and make the post. Today, I compare my results on M240(not the same day and not the same location and light) with Z7. Only 15mm has noticeable better performance at corner, (somehow) rest of 3 glass are all inferior at same aperture. By further inspect all the images yesterday, I notice there is decenter on all of them. right side has noticeable more blur than left side. Even 15mm has slightly but not as bad as others maybe is because it was start from f4.5. I am pretty sure this will screw up my mid frame and corner results at this pixel density.

This is really sad again remind us why we need a high quality adapter for sensor like Z7 and why we want use native lens as much as possible. FTZ feel so much better by comparison.

However, I won't say my effort was totally wasted. If you ask my opinion based on what I saw here, I feel Z7 is too good on M to ignore. They are still not bad at all for 35 and 50 after f4, but I think all of them potentially have better results, especially on mid frame and corner. Before my next adapter arriving, for now, I can only offer this much. FYI.

Good that the IBIS is working as it should.

You mentioned that you'd had to shim the adapter for correct infinity. Could you tweak the shimming to improve the decentering?

Thanks so much for all the effort you put into this. It reminds me of my trials and tribulations with adapters for E-mount. Eventually I just sucked it up and bought the VM-E helicoid from Voigtlander and it solved all of my woes. I'm keeping it in case I take a dip into the Sony waters again.

My local dealer called me today and told me that they got in a Gabale M to Z mount adapter so I went to pick it up before my dinner appointment with some friends.
Only managed to get a few shots in at a mall near the restaurant.

bentley by Suteetat S, on Flickr

With Leica 50/2 Apo @ f2.
I set non CPU lens data to 50mm f2 . Unfortunately nothing was registered properly in exif data. Camera information was 0.0 focal lenght, 0.0 aperture. Shot information recorded as focal length: (in 35mm: 5mm) which is really strange.
However, when I choose non CPU data for the lens, auto ISO appeared to work properly. When I had 35/1.4mm on, the camera in A mode with auto ISO on was working properly and shutter speed was kept at 1/40s minimum.

I set non CPU lens data to 50mm f2 . Unfortunately nothing was registered properly in exif data. Camera information was 0.0 focal lenght, 0.0 aperture. Shot information recorded as focal length: (in 35mm: 5mm) which is really strange.

Pic looks good... the APO is a damn good lens And TINY...

Good that the IBIS is working as it should.

You mentioned that you'd had to shim the adapter for correct infinity. Could you tweak the shimming to improve the decentering?


Yes, it could be because of shimmer I put. In this case I need put almost 8 sheet thickness of aluminum foil to get correct focusing. The adapter only have four tiny screw to hold M mount side. Novoflex has six total. I will try to work on it later maybe just remove them all to get another data point. However, one out of four already show sign of "screw up". I don't know how much I can improve on it.

Having said that, this is for test purpose and I might be able to squeeze a little bit more performance on that three glasses. For real world, it is really good enough for either WO daily or stop down landscape shooting.

Thanks so much for all the effort you put into this. It reminds me of my trials and tribulations with adapters for E-mount. Eventually I just sucked it up and bought the VM-E helicoid from Voigtlander and it solved all of my woes. I'm keeping it in case I take a dip into the Sony waters again.


I agree, I have both voigtlander and novoflex adapter with noticeable better build quality. They still require shimming though.

Interesting findings. So nice that you are posting results so we can learn from it.

I'm so happy I kept me M glass... so many options to use it on.


True, never sell M glass. Not necessary they keep value better but it is a hassle to get the same lens at same quality once you have a nice copy.

Thanks for the info. That is another clever way to verify Z7 take the info. One more info for non Nikon user, Nikon only give you the lens option that have legacy lens: You can't input say 37mm or 53mm etc...So for leica user, there is no 75mm option, no 90mm option. You still can find close focal most of the time though.

Beautiful image from 50APO, Suteetat, Since you are the only one who actually owned or is owning Z7, SL and A7RIII. I'd like to hear your opinion about IQ, ergonomics and Viewing experience, shooting experience if you are willing to share here. That will be a good information to know. Just offering another perspective from another Z7 owner. I maybe biased sometime with strong preference for one thing over the other. People here are usually less brand oriented for easy communication.
