I think the blooming aroung those christmas tree lights is mostly SA.
With the triangle like defocused light points in the corners I think it is mostly Coma,
but astigmatism can play a role here, too. These two aberrations are generally hard to separate.
But in your picture with the scale on the left it sure looks like there is a noticable amount of astigmatism, too.
Especially on lenses with high vignetting I always found city lights to be a much bigger problem
in regards to Coma than stars though.
These lenses with 3-4 EV vignetting in the corners, stars in the corners are so dark, the coma doesn't really become that obvious.
It's definitely SA. If we get the 35/1.2 III and stop it down to f/1.5, we'd have a very similar look. I think the glow is pretty in the sample images though.
Maybe I am very mistaken, but this lens has a much more crisp feel--the SA is very minor, and much less than the 35/40/50 1.2 I've shot. And at all distances. Below are crops from a modded a7--I took a series at 1.5, f2 and 2.8. One with dark subjects, and one with brights that SA shows up on more in my experience a bit.
Then I included 3 actual photos, at different distances, all WO. You'll see there's very very minimal SA. Now that you have your review copy, I'll be curious to see what you think. If it is SA, I am confused why I see so little on axis, but the affect is very noticeable with OOF lights. What Bastian said makes sense more to me.
It's not the same as shooting with the CV 35/1.2 III wide open which would yield even stronger SA. The spherical aberration is better corrected on the new f/1.5 lens but it depends heavily on distance. The closer the more SA.
I've tested it side by side to the Leica 35/1.4 FLE and the Voigtlander is noticeably softer at closer distance. All this is expected though.
Yes, that's why I included different distances as I know that the distance can vary the SA, though from .7 to about 20 feet (and I assume infinite, I don't see any change I am sure at absolute MFD I would see increased SA. I am curious to see your review and findings. And still curious about the affect!
Are you saying you tested the new 1.5, or the 35/1.2iii against the Lux FLE? I found the 35/1.2iii to have much more than this lens throughout the range.
