Yes, i wonder what they mean by Zマウントに最適化.
Have they optimized the optical formula?
The time they need to make this lens available would indicate that they may have.

The optical formula is likely very similar to Sony E but the lens housing is quite different. They even changed the filter thread to the Nikon-standard 52mm

Lenses are already added to the new catalogue:

The optical formula is closer to 50 f/2 APO in E mount than the 50 f/2 APO in Leica M mount. It has the 5 APD elements in the E mount lens and not the 2 APD elements in the Leica M mount version. It is a big thing, IMO, that Cosina has introduced the 35 f.2 APO and 50 f/2 APO in Z mount. I think we can expect most of the Sony E mount lenses to eventually be release in Z mount as these two are among the most sensitive to thickness of the cover glass and others should be even easier to make in Z mount. I would be very surprised if Cosina didn't adjust the performance for the slightly thinner cover glass of Nikon Z mount cameras.

I'm excited seeing the 50 APO coming to Z and I hope the rest of Cosina's excellent E mount lenses get this treatment even though I'm not wild about the styling choices. The 50 APO is on my shortlist of lenses that I'd really like to pair with a Z body and is likely a 2023 purchase.

I am very happy to see that Nikon Z users will now start having access to the wonderful CV lenses in a native Z mount. These high IQ, small, superb build quality, MF, lenses are a big part of my photographic enjoyment these days.

The 50/2 pair (VM and E) is an unusual circumstance - they are quite different lenses in AOV as well. Probably a bid to soften the wide open performance, given the likely uses of M owners. The 35/2 APOs also differ in performance and AOV despite sharing the same glass makeup.

I am noticing the 35/2 APO (E) has very tidy bokeh when you use f2.8 in most settings. F2.8 is one of the circular aperture settings, along with f5.6 which also shows this effect. For many compositions you can easily use f5.6 where f8 is more needed at 50mm for adequate DOF. So, as seen on p.1 #5 you gain a big boost in performance doing so. Even better colour in the 35/2, perhaps.

It has received little attention in the Sony world due to the other great new lenses at 35mm made by Sony and others. Hats off to Cosina for having the courage to develop very consistent cross-frame quality, they could easily have done what other Japanese makers have done and boosted the centre at the expense of outer frames.

The Z APOs look identical in claimed MTF to the E versions, at f2. Overall from a Sony user perspective, the new Z lens additions might spur Cosina to do more for us non-Leica people - more potential buyers for each design development effort.

For those wondering (like me, 2 mins ago) here is the announcement:

https://nikonrumors.com/2022/02/24/cosina-officially-announced-three-new-voigtlander-lenses-for-nikon-z-mount-50mm-f-2-35mm-f-2-and-23mm-f-1-2.aspx/

TL/DR: 50 f2 and 35 f2 APO Lanthars for FX!!

I love it. Will definitely buy when they become available. The best part is that these are MF, meaning they WILL BE IN STOCK all day because most Z shooters prefer huge lenses with AF like the 24-120 Z that will be backordered for a long time.

When I shot Leica, the 50 APO was a dream lens. This is an FX Z mount APO with better MFD than RF lenses, plus focus peaking without needing Visoflex 020. Basically everything I wanted in a rangefinder lens on a native Z mount with smooth MF and small footprint and good availability! Can't wait for this one!

I'm glad this announcement came out because I was a couple days away from buying a sony camera just to use voigtlander lenses. Now that body $$ can be used solely for lenses.

Different lens performance, M to E versions for BOTH 35mm and 50mm APOs. Hopefully Nikon users will get the E version, because it is quantifiably stronger wide open, around 5-7% by my estimation. See and compare the factory verified MTF charts, bottom left of each page:

50mm

E vsn: http://www.cosina.co.jp/seihin/voigtlander/e-mount/e-50mmF2/index.html
VM vsn: http://www.cosina.co.jp/seihin/voigtlander/vm-mount/vm-apo50mmF2/index.html

These differences may be due to different thickness of sensor stack. Results on the Nikon Z, whose sensor stack is different from both Leica M and Sony, may differ. That said, that may be going either way, i.e. it is possible that the E version is farther ahead of the M version on Nikon Z than the data suggest.

Well at 50mm the optical designs are obviously different and even though that isn't the case at 35mm the design goals are likely to be different. It is important that Leica M lenses are both short and have a narrow diameter so you don't block the viewfinder. To many who shoot Leica M that smaller size is really important. You can't block the EVF, so a bit bigger size isn't going to create the same issue. Given that the E mount lenses can be a bit bigger it isn't surprising that they are a bit higher performing. From my perspective the performance of both versions are excellent and I think you should pick the lenses that work with your system. If you want Leica M, then it makes little difference that a slightly higher performance exists for E mount and now likely Z mount. If you want a mirrorless camera with an EVF, then it probably matters little that a slightly smaller lens exists for Leica M mount.

This information was provided because many will read threads that do not differentiate between the two versions. They vary in important ways, notably wide open. It's of interest, seeing the attention devoted to WO image quality in the Leica M world.

5-7% may not be 'slightly' to others; if I had anything that was worth that much more, I'd be inclined to use other words. 'Substantial' comes to mind. You even allude to it: 'they are a *big* higher performing'

IMO, you are making too much about the MTF differences. Five to seven percent contrast at 40 lp/mm at already high levels of contrast is hard to see even magnified at 100%. Both lenses are very sharp. IMO it is a slight difference, but of course YMMV and that may be more important to you. To me it is clear that keeping the lenses smaller for Leica M was more important than that slight difference in sharpness for Cosina. I think they made the right call there, but you of course are free to disagree. I bought the 50 f/2 APO for Leica M mount, but if it was any bigger I would not have bought it. I won't buy the 35 f/2 APO for Leica M mount as I simply find it too big on a Leica M camera, but that is just me. Again differences of opinion on such matters are to be expected, but personally I find the 50 f/2 APO to be just barely acceptable in size and the 35 f/2 APO to be too big and both to be plenty sharp enough even though they don't quite match their mirrorless brothers.

Why are you guys discussing / speculating about M vs E design when the product pages of the Z version clearly show it’s the same design as the E version, including MTF? There will be no surprises when it comes to performance - it will be excellent
