Tim hard to tell on my iPad but looks pretty good. Can you upload the raw and I'll look at it later today. I'm taking the morning off to play golf. My hobby. Lol

I'll try to do it tonight...the upper right corner looks the worst, but it's very fine branches and leaves up there. Can't remember if there was a breeze at the time.
Not as good as Choppy I think, but not as bad maybe as other samples posted.

Has anyone checked the M mount version on an M240 or a Kolari Modified A7/A7r for corner sharpness?

Hi Rich,
I may have posted this already, but I have the 15III in M-mount and use it on the M240. After re-reviewing the tests I did last year with it, I would say my copy is between Fred's and Choppy. Corners are on the soft side, but don't look as smeared as Fred's and Boris's examples. However, they also don't sharpen up as well as Choppy and Chuck's copy. Near distance subjects in corners seem to resolve a lot better when the lens is at infinity than infinity subject details in the far corners. On the Leica M there might be slight field curvature towards the camera at the edges. Also, my copy appears to have a slight loss of resolution in the left mid zone area.
As I wrote earlier, something that struck me with sample photos by others was that the 15III looked a bit better in the outer zone on the Sony cameras than on Leica. It could be optimized closer to Sony specs than Leica. Somewhere in the middle so that it's decent on both, but maybe slightly better on Sony.
Boris: I would exchange it. I have no confidence that the Voigtlander distributor would have the means to service the lens, which means they would send it back to Japan, which would probably take ages to turn around. The more these are returned as unacceptable, the sooner Cosina will get the message that something isn't right. Also, from my impressions reading Roger's blog posts, it seems that fiddling with UWA lens element alignments is very, very difficult when it comes to lining everything up for perfect performance (assuming it's even possible).

Hi Ron,
Thanks for the input and response. I wasn't really expecting to purchase one of the CV 15III lenses. I will just rely on my WATE and my M 24mm f3.8 Asph with my A7rM V3 and also use my soon to arrive A7r with my WATE (less often) and my R lenses primarily though the R lenses will also be used on the A7rM V3.

Been following this thread and would like to thank everyone for their input, very interesting indeed! I had my mind made up that I would be buying this lens for my A7ii, probably not now though! I can't really take a chance on a lens of this cost with there not being a return system in Sweden! Question: Loxia 21, does the QC seem to be more consistent than the voigtländer? Would help me make my mind up

A question for those using the M version on an A7 series camera:
How important is the adapter thickness for optimal performance? My Kipon adapter is too thin. As a result infinity is way before the hard stop.

I will return it and decided to not try another one. The chances of getting a great one seems to be less than 1:10. I will get the Batis 18mm instead and live with the 3mm more focal length. I would rather prefer 15mm (and 58mm filter size and real MF) but I'm not willing to buy 10 lenses and return 9 to get a great one. I really hope that we will see a 15mm Loxia in the near future.

i do not believe that the cv 15/4.5 has a floating element, so a short adapter should not impact performance.
having said that, an accurate distance scale is very nice to have on such a wide lens, so i'd probably shim the adapter.
also, symmetry issues will show up to a larger extent with ultra wide lenses than with longer lenses.

Just to make sure, I would get the CV adapter to go with it.
FYI:Guy's choppy had a cheap Fotasy adapter and it worked great...but it was not the adapter that made his lens great. I tested my CV adapter on his lens and the images were identical.

Yea after Fred tested the adapters on Choppie . I may just glue that cheap adapter on. I honestly don't think from M to E adapters could have much variance if any. Its a real simple adapter but I agree with Fred get the CV adapter as you just never know. There not that expensive anyway.

does the CV adapter allow you to adjust infinity the way some others do, i've forgotten?

I decided against the close focusing adapter since I only had a 15mm which i really don't think anyone needs for the 15mm but if your shooting some of there other lenses than the closeup adapter is maybe not a bad idea.
p.16 #18 · Official: Voigtlander 15mm f/4.5 III E-mount
I have the VME close focus adapter and it works great, except that I hardly ever use it and certainly not on the 15mm. The few times I've used it were on my 40/1.4 and 75/2.5 Summarit-M. It's a little on the heavy side . . .

i actually really like the macro stuff i've seen with the cv 15mm and helicoid adapter, more than i like 15mm landscapes to be honest.
