compared to my CV 1.2/40 wide open, this is excellent CA correction...
Cheers, A.
Sure, but the 40/1.2 doesn't have an APO batch
For me that was the only selling point of this lens compared to other 50's. I don't need pin-sharp corners wide open.

The Lanthar 50 has more of CA compared to the 65 brother, for example. But it has to be provoked (laterally), it's not something that will show up in most pictures. And even then it's easily manageable, in my experience so far.

Seeing quite significant CA as shown in the crop below (from phillipreeve.net) makes me even more hesitant. Maybe I should get the 65mm instead (which is currently cheaper), but I am pretty sure it will stay at home most of the time due to the size and weight. There is no such thing as a perfect lens... always compromizes.
I wouldn't call it quite significant. This is a 100% crop at f/2 in a worst case scenario and I am pretty sure that no "normal" person would notice it. I don't have a 2/65 APO for comparison but I don't think it would be 100% clean either.
With lenses like the Voigtlander 2/50 I just have to appreciate the level of perfection achieved but honestly the level of sharpness and correction it reaches hardly ever translate into better pictures for me. Lenses like the 1.2/40 or 1.2/50 are already well enough corrected for my uses so it solves issues I don't have.

Well for a crop from a 24 megapixel sensor, it is significant. I've had many non-APO lenses that performed better.
For product photography for instance, the sample you showed is a pretty common scenario, not a provoked one.
I am certainly not "normal" either when I spend > 1k on a manual lens
Could you compare the LoCA of your 50/1.2 stopped down to f2 with the APO Lanthar?

The sample shot shown is not a weirdly provoked scenario (shooting a backlit fountain wide open would be). It is just a regular product shot. If I can't crop to 100% without seeing CA, then a lens is not good enough for product photography.
Correct me if I'm wrong which could be, as I don't have much interest in product photography, but doesn't it normally involve stopped down shooting (where the CA issue is moot)?
In my previous post I was referring mostly to portraits and landscapes use of the lens. LoCa can be seen in certain scenarios WO, but not in most images in my experience so far. That's where a good correction stands out (here I'm comparing mostly to Zony 55 which I extensively used, and Voigtlander Nokton 40 which I had shortly).

Mind sharing a sample with better correction? I take my product images with a longer lens stopped down to at least f/8.
I don't have a 1.2/50, just a 1.2/40. Will see what I can do.

I sold all of those well corrected lenses (either different mount or I didn't use it often). As far as I remember, the following were almost flawless in terms of CA correction:
- Olympus 12-40mm
- Olympus 60mm F2.8
- Sigma 56mm F1.4
- Sigma 60mm F2.8
- Sigma 70mm F2.8
- Samyang 135mm F2
- Laowa 100mm F2.8
I will compare it to the 65 and 110mm Voigtlander when my copy of the 50mm arrives. Not much sense with the 110 as the focal lengths are so different. Both will be better suited for product photography, since they can reach much better reproduction ratios I guess.
I can toss a Loxia 50 into the mix as well- just for the giggles.
Sadly no CV 50mm 1.2 at hand.
From what I have seen so far, among the CV APO lenses this one seems to be the weakest with regards to CA correction, but still easily very good. Just not perfect.
With the 65mm it is also possible to evoke some CA, the 110 is damn near perfect.
Not the most exciting subject (well, maybe for some), but I wanted to see how everything looked at f 2, 2.8, 5.6 and 8. Auto WB and auto adjustments in LR.
My camera was definitely not completely parallel to the subjects, it seems. Focus point was on the Macallan label on the bottom row. Colors look really good as does sharpness. Hard to tell at this resolution, though.

I have been using it for a week now and starting to get a better hang of it.
I took it out for a protest as well, the weight and size makes it really easy to carry around.
The micro contrast, the color, the sharpness etc makes the overall image it create really stands out.
I don't actually need to do much editing at all.
Unlike the 40 1.2 which under some situation can show very obvious flaws (the off axis softness, the strong purple fringing, and the CA)
But occasionally I find the way it renders bokeh (background) to be a bit distracting.
I am planning to find a day and shoot a bokeh test compared to F2 on the CV40 to see if it's due to the F stop difference or it'ss the rendering.
I will be updating the album from time to time, please have a look
(I also have a CV40 album)
Kids are mostly too fast for lenses with real helicoids, especially post holidays sugar-propelled ones. This time my son sat down long enough for me to take a few images.
I gotta say, sometimes I chuckle at the thought of using only MF lenses on the body with such advanced AF system like the one found in A7R IV. And I somehow ended up doing that exclusively.
Cameraquest has the 50 APO in stock. I just got a shipping notice and their website says they have a few left after preorders. I hope posting this doesn't break any forum rules. I have no affiliation with them other than as a customer.
