Hi Jürgen,
I use the Novoflex adapter on Stefan's recommendation. First I tried the "Fotodiox adapter" but that was quite crappy. The Novoflex is cleanly made. It consists of two parts a Canon back end and a Hasselblad front end.
The Novoflex has rather small internal diameter, but I don't think it matters. There is some shading with shifts above 12 mm, but I think it comes from the internal baffles of the HCam Master TSII.
For the Pentax I bought a Kipon (Pentax 67 to Canon EF) adapter. It is similar to the Novoflex, although the black painting on the inside of the Novoflex is better (more matte and less glossy).
I have tried the Planar 100/3.5 and the Distagon 60/3.5 with "shift panos" on the A7rII the Planar 100/3.5 was pretty good and the Distagon was quite OK.
Best regards
Erik
Thank you Erik for showing these interesting combinations .
Can you please give some info about what adapter and adapter/lens holder you use for the HASSELBLAD solution ?
Thank you .
