Compared to the Z 50/1.8 S, the CV 35/2 AL-Z is much more compact.
It is not only the length, 67mm vs. 87mm, but with identical focal length and the CV 50/2 AL-Z it is even 61mm vs. 87mm.
In addition, the Z 50/1.8 S is significantly thicker in circumference.
Even my Canon FD 85/1.2 L looks downright dainty compared to the Z 50/1.8 S, if you consider the key data 85/1.2 vs. 50/1.8.
Left Z 50/1.8 S, middle nFD 85/1.2 L, right CV 35/2 AL-Z.

The differences are considerable in practice.
The 35/2 Apo Lanthar still feels really compact and liberating in terms of dimensions, unlike the Z 50/1.8 S in comparison, which is quite bulky for a 50mm f/1.8 and has a different presence in use.
If 50mm weren't underused by me, especially as the Z 50/1.8 S doesn't leave much to complain about optically and I also own various vintage lenses in this focal length range, Tomioka 55/1.4, Biotar 58/2 with 12 aperture blades + A. Schacht Ulm M-Travenar 50mm f/2.8 R (Zebra), the CV 50/2 AL-Z would be an absolute no-brainer.
Although optically excellent for the price, I never really warmed to the Z 50/1.8 S.
As I said, it's not because of the output, but because it's simply far too bulky for an f/1.8 50mm.
When I use the Apo Lanthar on the Z6, it really feels like a very compact unit.
Extremely carefree, light and very compact.
With the Z 50/1.8 S this feeling never arises, it simply always feels clearly too big for a 50mm of this speed and never gives rise to this liberating minimalism, as with an Apo Lanthar or one of my tiny vintage optics such as the Takumar 35/3.5.
I generally have no problem with big chunks if the end result justifies it, otherwise I wouldn't have bought the Plena.
It just has to fit the key data and a 135mm f/1.8 has the corresponding substance.
Weight and dimensions feel right with the Plena, but not with the Z 50/1.8 S.
Accordingly, it is used very little, as the Apo Lanthar is simply always much more satisfying to use, in terms of compactness and also when viewing the final results....Show more →
Thank you @Vento that’s very helpful. Circumference matters! I’ve put my Ai 50 1.8 on with an adapter, it’s about the same total size as the 35mm APO and yes it small, not as small as the 40/1.2 but small enough.
