I cropped out the vignetting. This lens is totally useable on film for infinity shots as well as up close. It really is built very well, and handles very nicely. And one thing I like about a $200 lens? I don't worry about protective filters..


Are you saying that with a film M, the 'hard' vignetting does not show as much?

No it is the same. You need to crop it out. What I mean is that once you calibrate the focus using a digital M, focus is accurate via rangefinder on a film M (no other way of focusing!).
On a digi M you could cheat and use live view.

Focus was waaaaay off via rangefinder on both film and digital Ms until I calibrated. So far off it was obvious TTA did not even bother. I guess that is how they can sell it for $200..

it's too bad about the vignetting. It's like shooting with a APS-C lens.

Yeah thatís how I described it earlier in this thread as you have to treat it like a 135mm lens if you donít want the hard vignetting. But it is a very interesting lens. And very cheap.

The M-mount version likely has reduced vignetting when attached to a mirrorless camera body due to the additional spacing.

I just tested it on my Z7, using a Kipon adapter. At 2.8 no vignetting, 4 slight but not really noticeable. F8 the hard vignetting kicks in.

It's weird, it seems like it is an APS-C lens but philipreeve (Bastian's site) tested this on a Sony FF with no issues at all. I've emailed for a refund or exchange if mine is a one-off.


Quoting myself to answer your question Fred.
The M mount version is a bit better adapted to my Z7, but if you donít want vignetting get the non M mount version.
