@Steve Spencer@@@@@@@@
Given the optical diagram, have any guesses on what type of compromises we'll see? Something like the CV 50/1.5ii or more like the rendering based CV 35/1.2iii or otherwise?
Hi Nehemiah,
Given the optical design, I expect it to be fairly close to the CV 40 f/1.4. I kind of hope so, because I really like that lens, but on a Leica M you don't get 40mm frame lines. The compromises in that lens, which I used a lot in Sony FE mount, are as I see it corner weakness until well stopped down and even then not the greatest corners. It also has quite a bit of axial CA until stopped down to f/2.8 or so. It also has pretty high vignetting, and the lens loses sharpness as you focus closer. Despite these compromises it is has pretty decent central sharpness even wide open and fairly nice bokeh, and if you stop it down to f/5.6 or 6.3 it has pretty decent performance across the frame with pretty low aberrations. Another way to say it is that at or near wide open it is a pretty decent portrait lens and stopped down is it performs quite well for anything you would want to use it for. Of course 35 f/1.5 isn't that different from 40 f/1.4, so I am hoping for a 35 f/1.5 that is pretty similar to their 40 f/1.4 and the lens diagram suggests to me we might just get that as it is not too different from the 40 f/1.4.
Interesting Steve. Thanks for sharing your thoughts. I am less intelligent with the optical diagrams than most here, so I just wait to look at images.
Given they have 3 versions of this lens with different materials, and CV is fine with doing MC vs SC and such for a particular lens, I do really with they'd release a "C" for compact version of theses lenses. Don't change a thing optically beyond larger elements to cut down on optical vignetting--bump this new new 35/1.5 with a 39mm thread to 49mm or 52mm for an alternative version. Just a thought/hope that won't happen. I personally dislike the high optical vignetting in lenses. And it seems a lot of other shooters do too.
I think they basically have that lens is the 35 f/1.2 III. It is bigger and has les vignetting and for you they even have it in FE mount. If you don't like this lens, then I think you might very much like that one.
Yes—owned and shot it. But it’s much larger/heavier than this new guy. If this new one is a mini-me of the 35/40/50 1.2 formula, should be a winner.
Unfortunately, I think the smaller size of the new guy (i.e., the new 35 f/1.5) means it will have more vignetting and perhaps another compromise or two that the bigger guy (i.e., the 35 f/1.2 III) does not have. I think Voigtlander has a really nice lineup for Leica M mount 35mm lenses. You have the highly corrected but not that small 35 f/2 APO. You have the ultra fast but not that small 35 f/1.2. Then you have this lens which seems to be a compromise between ultra small size and likely performance in some ways. All of these lenses are very modern, but if you want the rendering of an older lens you can also get the 35 f/1.4 classic. That is four pretty great lenses for lots of choice, and for Sony shooters you can even get 3 out of 4 of them in FE mount. I doubt this new one will ever show up in FE mount (just like the 75 f/1.5 and 28 f/2 II), but Voigtlander has still brought us a lot of really nice lenses.
There is also the 35/2 Ultron which is actually the lens I have settled on of the all m-mount 35mm for my daily driver. And I’ve owned them all except the APO (at that size, I’ll take the ZM 35/1.4 and just stop down to f2 but have the 1.4 if wanted). Have owned multiple Leica’s and ZM’s in 35mm land too. It’s not at all a perfect draw, but the best set of compromises for my preferences.
Yes, there is the f/2 ultron as well, which I left off the list. Thanks for bringing that up and reminding me (us). I never bonded with the bokeh from that lens, but I understand why people like it.
I just noticed it was forgotten  The 28/2ii does have some heavy optical vignetting, but I do love that lens—in fact, to my mind, it’s probably CV’s best all things considered. If we get a pretty similarly smooth draw and that degree of optical vignetting and overall superb technical IQ with the 35/1.5’s size, I’d be pumped.
To expand on Fred’s observation, I do wonder if it’s not only the front element (which we know) and the back element, but also the relationship or ratio of those two elements to each other, and also as a block to the sensor.
Would love someone to read someone explain this.
