That's right, the abrupt focus transition. For a longer lens with large aperture it may or may not be relevant. But for such wide angle it certainly help tremendously. I've seen this very characteristic on the 21lux as well (or was it the 24lux).

I observed the same with my CV 28/2.0 Version I in the past. I will keep my copy. Wouldn't be surprised if this older lens version will be hyped up online in a few years due also to this effect with increasing prices.

Trying to decide if I should six-bit code my lens. What code are folks using?

I believe that Fred is using the code and processing (at least some of the time) for the Leica M 28mm f2 Summicron Asph. Since I am using my lens on my Kolari Vision UT sensor modified A7rII and have no M camera I am not coding my lens.

Curious if you've tried the Voigtlander 50mm APO with the SL2. It's been on my mind to pair it with my SL2-S...

Fred Miranda wrote:
Yes, it's a great suggestion Rich. I've tried that before and the results are pretty much identical. I find that the the 6-bit coding is great correcting "color vignetting", usually magenta.

Regular vignetting and distortion are corrected in-post and not in-camera.

Regarding the better performance on the SL sensor for Leica lenses (vs Voigtlander), it must be something in their optical design to be more compatible with the micro-lenses array.

For some reason the cv 50/2 APO does not work optimally on the SL2 sensor. It’s way better than using on the Sony though.

Thanks that's slightly dissapointing. Wonder if that's true for the remaining Voigtlander 50mm lenses as well as they kind each have their own strength. I have the DR Summicron and a Canon Dream Lens I can use but was looking for something with a more modern rendering and the lack of a Aperture ring on the 50mm SL drives me crazy

I speculate that the reason Leica M lenses perform better than M lenses from other brands (like Voigtländer) could be because of exit pupil distance; that Leica M lenses have a longer minimum exit pupil distance than the competition.

What do you think?

Yes, it gotta be something with the lens design + SL sensor's microlenses array. Having said that, the CV 50/2 APO M is outstanding on the M-sensor. See here: https://www.fredmiranda.com/forum/topic/1707236/0#15636310

I tested both Leica 35/1.4 Lux and 50/1.4 Lux on the SL2 and performance it pretty much identical compared to the M10-R's sensor, so Leica lenses have this advantage. The Voigtlander 35/1.7 Ultron is not optimal on the SL2 sensor either. Of course this is pixel peeping at the very corners. They still perform great, especially compared to using them on a Sony sensor.

p.14 #9 · p.14 #9 · Voigtlander 28mm f/2 Ultron II Review

I just checked the 28mm Ultron II video review that Benj Haisch did again, and here he actually says that, imagining that he could go back in time and choose between the Summicron-M Asph II and the Ultron II, he would have bought the Ultron II. He doesn't consider the Summicron an upgrade to the Ultron II. Now that he already owns the Summicron, he will keep it, though.

I think that if using the 28mm lens mostly at shorter distances; shooting people etc., then the OOF qualities will be more important than corner sharpness which means the Summicron will be the better choice. For landscape and architecture photography, the Ultron II may be better since it's the sharper lens!

For Leica M shooters, another advantage for the new Voigtlander 28mm is having less frameline obstruction compared to the 28/2 cron.

I've posted a Voigtlander 50mm f/1.2 Nokton vs 50/1.4 lux comparison (resolution + rendering) and from the results, I'd say that's another Voigtlander winner. Can't go wrong with Voigtlander 28/2 II + 50/1.2. (regardless of price difference compared to the Leica alternatives)...There is also another one but its discontinued: CV 35/1.7 Ultron. It renders like the 35/1.4 lux and it's way sharper, especially off-axis.

I current own Leica bodies and lenses and love the haptics, quality control and build. However, the latest Voigtlander lenses are giving them a commendable competition in terms of resolution and rendering.

Thanks for adding to my comment.

I have the Nokton 50mm f/1.2 VM myself and just love how it renders. While it does have some (regular) field curvature which means the corners won't sharpen up fully when focusing in the center at infinity, the mid-frame doesn't have the sharpness dip that the Summilux-M Asph is reported having.

Regarding the 28mm Ultron II, I tend to use the 28mm focal length mostly for landscape or groups of people, so the Ultron II might be a better choice for me than the Summicron Asph II. I will find out when I have them both. The Ultron should be at my doorstep by the end of the week while I am still waiting for Summicron to return from Wetzlar.

(I have owned the Leica lens for about nine months now, but most of the time it wasn't in my possession, but in Leicas. Who needs super expensive gear that you need to send in for service repeatedly?)

In Ben's case, I pretty much agreed.

As for the rendering compromise, the V1 cron has poorer corner performance than V2 but here are two examples of what I was talking about, it has some sort of cut out look. First one being close range portrait, second one is a tree trunk between 2-3 meters (window was down).

Just want to confirm that the 2 pictures you posted as a cut-out look, are they from 28 cron v1?
I like 3d pop and I see that more with the images you posted and also Ben's video of comparisons. Voigtlander seems sharper but I like 3d pop more and softer bokeh than swirls! 😁

Right. I think he at first thinks definitely, but then he moderates himself saying "probably" since he (apparently) has decided to keep the Leica lens because he is now used to it. He says that if the Ultron II was on the market before he bought the Summicron, he would have gotten the Voigtländer since it is no downgrade compared to the Leica lens (if I understand him correctly).

Yup, that's the 28 cron V1. I'm not too particular about corner sharpness and it performed fine f4 onwards. I don't shoot landscape often and when I do, I usually crank it down to f8 anyways.

I bought it few months ago as I read posts suggesting the V1 had something special about it from V2 owners, and I don't regret about the purchase.

However having great corner to corner performance wide open is still very tempting, maybe will give the ulton ii a try when time is good after this pendamic madness.

For rendering comparisons we need side by side tests when both lenses have the same specs since the subject, background, focus distance, distance to background etc. is a big part of the equation.

have you seen any real world examples in harsh light at mid distance? I have on both those lenses but at different times. I think the CV is actually the smoother rendering and would be surprised if it was very close.

Which lenses? 50 lux vs 50/1.2 or 35 lux vs 35/1.7?
