Here is the crazy part with Proxar on its better at 2.8 in the corners than with it off at F8. Its that much of a difference. Im floored
The ZM 25mm with Proxar on takes at 2.8 takes the GM to match it at F5.6
Wow, great results
There are some versions of Proxar 1m, having different diameter e.g. B57, B67, A42 and A28.5. Which one are you using?

He is using the B50.
I know that because he got it from me.
Hmm, that ZM25 looks really interesting to me. I would like the focal length and it would be great to have a high contrast WA with nice sunstars and good flare resistance. Guy, if you could point it towards the sun and take some pictures that would be a great help.
Yea I have to do more testing for sure but so far very impressing. I'm just stuck on a house painting my exterior. So I'll get to it soon

On the paperwork I have it says Hasselblad Proxar B50 but it could be wrong.
Is the diameter of the lens 50mm?
As far as I understand there are Ø50mm = B57 (description bayonet for Hasselblad lenses) and Ø60mm = B60.
But maybe I got that wrong, so I would be interested in the diameter of the lens.
It's confusing because their description shows "B50" but if you look at their picture, the lens is marked with "B57".
As I expected, thank you very much!
These H'blad filter bayonets are quite confusing...

As far as I know B50 and B57 represent the same filter format. Also B67 = B60. Yes it's quite confusing...
I own B57 Proxar 2m. Its bare lens diameter is 50.8mm (2inch). I expect f=1m has the same diameter.
I was able to test the Contax 28mm f/2.8 G with the PCX 1.5m (in reversed orientation) front-lens today.
This is one of the first lenses tested by @HaruhikoT , and I see similar findings. There is little improvement in the center but there is big improvement towards the corners. See crops below at f/2.8, f/4, f/5.6 and f/8 (extreme corners)
Best of 3 for each aperture. Same sharpening settings for both.
I used the Kipon adapter and didn't have to adjust the lens in an way. I'm actually able to focus pass infinity with this adapter and the front-lens.
