For the way I shoot, CA isn't too much of an issue and it is easily dealt with in post. As much as I love this lens, I still find myself using my 50 1.4 ZA most of the time. I'm probably going to sell the CV 50 APO and pick up something in a different focal length.
Saxguy, do you use the 50 1.4 ZA most of the time because it has AF or because of some other reason?
I have a Loxia 50 and the 50 1.4 ZA. They complement each other very well but the idea of having one small lens that can do it all is very appealing if all else is equal...
Hi Marc, could you expand on your comment please, the lot of CA bit.
You appear to test a lot of lens from your flickr account, is your statement in comparison to the the other APOs you've tested or even just other lens in that focal range.

Interesting, never thought that could be an issue. Do you happen to remember which brand it was?
I use a cheap extension tube (Meike), but it does have a slight angle at the mount towards the contacts, so I don't think it will break a pin...
The brand that broke the pins on my A7r or r2 (can't recall which) was Commlite. But I think a lot of the cheap ones are the same just different badging (or maybe assembled from the same parts). Don't risk it. They also show reflections sometimes, and the Kenko ones are flocked to prevent that (you can of course do that yourself)
A lot by what standard? I haven't tested a 50 with less axial colour. And the principal kind of axial colour this ones displays is PF which is a whole lot easier to get rid of in post than spherochromatism.
Just ordered a copy of this. Plan to use it primarily for aerial landscape photography where the great edge to edge performance wide open will be advantageous in keeping my ISO down.

That is a really ideal use case for it.
Just hoping that focus around infinity isn’t too touchy. My plan would be to pre focus it before the flight since everything should be at infinity when shooting from a plane, just need it to be easy to refocus if I bump the focus ring in flight or something.
I suppose it will also take over from my CY35-70 for landscape duty on the ground at 50mm.

lot of CA compared to the Voigtlander 65mm F2 Apo Lanthar
The levels of purple fringing in that tree shot is high for any lens. Use the link provided to view it at 100%. I am very surprised at that level of PF for an APO designated lens. I don't think even my old Sigma's from the 80's (180/5.6 APO macro, or 180/2.8 APO macro) have have ever shown that level.

Yes, I also find the focusing to be a bit to sensitive around infinity - not quite fiddly as macro Lanthars, but not as precise or with more resistance as Loxia 85 either (which I prefer).

That (infinity) is a tough one with this lens.

Note the range around infinity.

Oh well I guess I’ll see. My typical approach with MF lenses is just to memorise where on the markings I need to position focus to achieve true infinity. As long as this position is able to be determined ahead of time and easily repeated I should be fine. Worst case I can always mark the true infinity position in some way before any flights I guess.

Hope, you will not mark anything as it will change with temperature. That is why there is a range.
I hear this a lot but never once have I experienced it with any lens I’ve ever owned. I live in Sydney and can buy a lens, test it on a 35 degree Celsius day and work out where optimal focus is and then take those learnings to shooting at -10c in the mountains without any issues.

Is any of those lenses made with all metal and with so many APD elements? This one is very different. You will see.
Most are all metal. I don’t tend to use first party lenses.
Currently I shoot mostly with a Loxia 21, CV15, CY35-70, CY100-300 and occasionally a CV90. My old 50/2 was the Zeiss Makro-Planar model which similarly was an all metal build although I no longer own this.
Not saying it can’t and won’t be different for the CV50 as I’ve never used it but none of the above lenses have demonstrated any material focus behaviour changes based on temperature in my experience.
