Marvellous colours. Superb bokeh. Prone to CA. On Sony A7II: Has very slight weaknesses in sharpness, but is still performing very good.

TAKE CARE AND BUY THE RIGHT ONE! This lens exists in two versions: the older one is identical with the Meyer-Optik lens and you probably want to get that. The newer one is a modified version, it only has 6 blades, thus it misses the superb bokeh of the original. If you are unable to have a look inside to count the blades, just check the minimum aperture at the ring. Is it 32? Good! The newer version only has 22 as a minimum aperture.

I'd like to ask for further info regarding the mount. I believe the first mount  (B) is an exacta mount, however if you unscrew the binding ring, beneath it I see another mount (A). Is this also an exacta mount or does this serve another prupose? Why can it unscrew in the first place?

Thanks!!
