I am sorry that I am not clear about this. For ZF.2 lens, Z7 have no problem control aperture and record EXIF even before this firmware update.
Leitaxed R or AIS or ZF lenses, you can't control aperture through the body. and if you change aperture on Lens, body won't know. EXIF can only show focal length and MAX aperture that you stored in their NON-CPU lens bank after this firmware update.

Hi, Mitch, based on my impression from your work, I'd say you can't replace M with Z7. Z7 would be a nice add on for you if you have some itch on shining new gear, but, you clearly state you don't want have duel body setup.
Here is my opinion about this:
First of all, sensor. This is one of most over rated spec on internet nowadays, There is simply no poor sensor anymore no matter it is from Leica or Canon. The difference is really not that significant for 98% of images we shooting. I compared my recent travel images from Z7 and M240 in China, I'd say I don't feel M240 is lack at all even on paper M240 should at least one stop worse. The real challenge case for M240 to get a nice image will also be a challenge for Z7, at least that is my impression. Corner case is really for bragging right IMHO. You have to decide let it go one way or the other to blow the highlight or shadow for difficult case. That is exact I don't buy those internet bragging about Nikon Sony over Canon or Leica.
As the one you mentioned about highlight blow up for M10. I have to say depend on meter and scene, I can easily blow up highlight of Z7, D850 or any camera I used if I am not careful.
Let's say you have 14 stop Dynamic Range on Z7 and have 13 stop Dynamic Range on M240. For a given scene within 13 stop, both will be fine. it is all about select right exposure fit the scene in this Dynamic Range, the more close to 13 stop, the more careful you need about exposure. For modern digital photography and most scene you can't control light, there is no right or wrong exposure anymore, but how you try to fit the image right there within 13 stop. Yes, you may need underexposure .5 to 2 stop as you said to avoid blow the highlight but we nikon users need do the same. The camera with more DR definitely give you a little bit better error margin, but affected cases I'd say is very small as long as my main subject get decent lightness, the good image will be good even with blow highlight or black shadow.
Now about why I feel you will not happy with Z as sole system by using M lens. First of all, performance of WA won't be 100% or as good as native Leica. Then, the focus is totally different. You need have a quite good eyesight and skill to nail focus no matter is WO or stop down. (WO is hard due to shallow DOF, but stop down is also hard because difficult to determine correct sharpness at much wide DOF) M focus is straight forward especially for small aperture and wide angle shooting.
I do eye ball manual focus for many years with either OVF or EVF to improve my skill and I have almost perfect eyesight, I would say I still can't optimize 45M sensor of Z7 with manual focusing if I want shoot fast. All EVF based focus aid are comprised and trade off games between speed and accuracy. M is way more straight in this case.
However, if you plan use AF glass, this is totally different story. One thing Z will help you is you can overlay histogram on EVF during shooting to avoid blow highlight.
I hope this help. my 2 cents.

Michael - First, the two shots of your boy reading in bed are simply wonderful, just perfect tonality. I've always admired your photography, and it's a pleasure to see your work here and on the Leica thread.
I agree with what you write on the possibility of my throwing in the towel on the M10 and getting a Z7 — this morning, when I went out, I came to the same conclusion. In Chiang Mai, at a large shopping center, I went to Big Camera, a large, high-end camera store chain. I asked to ask for a demonstration of manual focus and focus peaking with the Z6 or Z7. They asked me to come back in ˝ hour, as they didn't have a changed battery. I went to an Isan restaurant (somtam and grilled chicken) just one floor above Big Camera; after paying and leaving the restaurant, on the escalator going down, I reached for my camera, and the M10 wasn't hanging on my shoulder: I had left it at the restaurant. As I was running back up, I had a real sense of loss: thinking it was awful; now I wouldn't buy another M10 and Summicorn 35v4 lens — thinking, I would now get a Z7 or Z6 with the kit zoom lens I felt a sense of loss. When I got back to the restaurant, the waitress ran over to me with my camera: that had put it aside for me.
Down to Big Camera again, I tried out manual focusing. I found it was exactly as you described it: rather difficult to focus manually at the 24 mm setting on the kit zoom lens; I didn't much like the focus peaking: somewhat difficult. Although I didn't get good tryout because the salesman was not familiar enough with the M7 focus setting, my feeling is that I got enough of a feeling for the to decide to stay with the M10 — a feeling that is strengthened by what you've, helpfully, written. Thanks.
The Z7 is a wonderful camera:I wouldn't hesitate to get it if I was still going on African safaris, and needed telephoto lenses. Back around 2006-9 I had the D300, with the Nikkor 2.8/70-200 with the 1.4x tele-extender — and really liked that camera. Of course, the Z7 looks much better than that....Show more →
Thanks, Michael, that information regarding the EXIF makes good sense now.
I've been using M-mount and LTM-mount lenses on Sony mirrorless cameras since late 2011 when I purchased a Canon 50/1.4 LTM to use on an NEX5n. I can say without hesitation that I am highly skilled as regards manual focusing with an EVF using peaking/magnification: multiple APS-C and full-frame Sony bodies, more than 100 MF lenses in virtually every legacy mount except Pentax. Three weeks ago I purchased a Leica M10-P, which I've used every day with various 28mm, 35mm, and 50mm lenses. I've been stunned by the superiority of rangefinder focusing compared to EVF focusing. I also bought the Visoflex EVF because I wanted to be able to test lenses for focus shift and because I have a Biogon 25mm f/2.8 ZM. Apart from those special use cases I have no desire to use the Visoflex in everyday shooting because, to put it a little more forcefully than Michael did, the Leica M rangefinder is an order of magnitude easier and more accurate for lenses in the 21mm to 50mm range.
In the M-Mount Lenses on Nikon Z7 and Panasonic S1R MLC thread, FM user mapgraphs made the following observation about using M lenses on the S1R and Z7:
From my own usage, with the same lenses on M, Z7 and an a7ii, I would say that the Z7 matches the output of the M, edge to edge - However (big however), the higher resolution is less forgiving of miss-focus and sloppy technique. One can get away with a slight miss-focus on the lower resolution M or a7ii that would be quite noticeable with 46mp Z7. Also, issues like a slightly decentered lens that isn't that noticeable on 24mp really stands out with 46mp.
The only caveat I would add is that one's perspective does benefit from shooting M glass on an M. At least to be able to have a point of reference...
Unfortunately, this perspective is sorely missing because only a tiny minority of those who wish to use M lenses on Z7 and S1R bodies are aware of the issues that mapgraphs describes. To be honest, coming from a 43-megapixel Sony sensor to a 24-megapixel Leica sensor was the most difficult adjustment I've had to make. But the ease of focusing, the sense that one is floating through the world as opposed to being weighed down by equipment, and the discipline required from photographing with a Leica has more than compensated.
Mitch, there's no doubt that the Z7 is appealing for all sorts of reasons but I've been following and admiring your photographic achievements for a number of years now and I can't help but think that a Z7 is the solution for a problem you really don't have.
