Really enjoy using this lens except for infinity is WAYYYY OFFFFF. So much so you really had to think about focusing at infinity to get it perfect.
I didn't accomplish that on both of the shots below but still enjoyed them. Not sure if my copy has an issue or if its just what you have to deal with but its more than a few mm off-

You are sooo correct, sir. I don't know why they don't have a hard stop infinity on this lens and the CV50APO is not the only one lacking it. You would think a manual focus lens would be adjusted to true infinity so those distance shots can be captured without fiddling with the focus ring.
Well, I paid dearly for my copy, and it has a hard stop infinity. What a pleasure it is to focus distance with confidence.

The excellent Zeiss Otus lenses don't focus precisely at infinity at the hard stop, either. I suppose that Zeiss engineers understand that focus may need to be adjusted to account for thermal effects.
See for example: "the hard stop on the far end is a bit beyond infinity. . . ."
Just as oils ain't oils, infinity is not infinity. Cosina really should have popularised lens designations better. They (and others) refer to M-mount lenses as 'VM' but the other mounts for which they make lenses are just the lens designation. They should be 'VE', 'VZ' and VRF' to avoid the inevitable confusion, as we see in these combined mount lens threads.
Nobody who uses a TTL camera (remember that term?) needs to worry about ring rotation past infinity because they can see focus in their EVF (and OVF in the past, if they were lucky). Zeiss engineers did not make the Voigtlanders, Cosina did and, my word, they know exactly what they are doing.
In fact, ring rotation past the infinity index marks the lens as a serious optic, one that can be used no matter the conditions, and lens/mount tolerances. CZ and Cosina want you to do your own infinity focusing, because they are aware of these issues and the ultra fine tolerances involved in exact focus acquisition with the better lenses.
Infinity is not always the same, and 'optical infinity' enters the fray - not to get into that now. And astro has added more problems to the issue, as well as AF overshoot needs. And a lot of people don't realise you give up DOF when you focus at 'infinity', so what seems straighforward is anything but.
A reasonable fix, if you do the same work over and over and therefore have 'your infinity' defined, is to note where it lies on the distance index, and use that setting.
Hi all, Ive been meaning to buy this lens for ages, but I already have the Nokton f1.0 and the 3.5 50 Apo Lanthar is coming out in august..
Im thinking to wait for the 3.5 as surely that paired with a Nokton 1.0 is better than a 2.0 Apo Lanthar in this case?
I guess I'll wait for the reviews to come tumbling in..

Munro303 the MTF charts for the 50/3.5 Apo-Lanthar are now available on the Cosina-Voigtlander website. The performance is excellent but not at the stellar level of the 50/2.0 Apo-Lanthar. Of course the new 50/3.5 versions have impressive close focus that would offer a distinct choice to the 0.9 meter limitation of your 50/1.0...If that is important to you.
Im going to try not to buy both haha! But going to finally buy the 50/2.0 Apo-Lanthar. I have the 35/2.0 Apo-Lanthar and it's on my camera more than any other 35 even though it's such a large lens in comparison to others.
The performance is just so incredible with these CV Apo lenses
John, I have the 50/2.0 Apo-Lanthar also. It's almost always mounted on my M10M (my avatar here) and the resolution is just unbelievable. Up until when the 40MP M10M files pixelate (just above 300%) that combo stands up to my 100MP GFX100S with the GF 63/2.8 in performance.
I know what you mean about trying to not buy both. I've got too many 35 and 50s already but it happens ;-)
I just ordered the 50/2.0 Apo-Lanthar on Taobao as Im currently in Shanghai, it should be here in a couple of days- looking forward! Incredible how it can stand up to a medium format GFX.. amazing.
Snatched up the Z before it disappears...looks to perform just like the 35, which is a great thing. Having nearly identical colors from each lens will make it easy to stay consistent in post.
