Thanks. There's also the option of adapting a Canon 50mm TS-E (I have the Techart adapter), which would give you a similar FOV I think, unless you use the 0.8x Hasselblad adapter. I wonder if the HCD 28 would provide better optical quality and/or shifting ability than the Canon.
The Canon 50mm ts-e is very strong performer on the Haselblad together with the other new Canons ts-e and if you have a good copy’s of the 24 and 17mm if you can live with only 12mm of shift a little less for some of the canons due to vignetting.
Here is a reply from an other thread with my experience as a professional architectural photographer:
”I think I have used all the wide angles for tech cams from Rodenstock and Schneider in that focal area and the Fuji is overall the strongest performer, if 15mm of shift is enough.
The ”new” line of Canon ts 50, 90 and 135mm works very well on the Hasselblad - I have used them a lot on the X1D and now on the GFX 100II
The 50 with almost no vingeting at full shit - the 90 a little bit at full shift and the 135 starts at around 8mm of shifts.
They are almost as good as the Fuji in terms of sharpness and detail but only with 12mm of shifts compared to the 15mm on the Fuji, but in size smaller as well.
Good copy’s of the canon 24 and 17mm ts also works well with a bit of vignettimg at full shift with the 24mm a bit more on the 17mm, but that is also extreme an extreme wide when shiftet full.
You have to learn where to focus in the frame with the 17mm to get a sharp images in the full images circle - but it’s absolutely possible.”
A big plus with the Canons, there is no practical distortion! there is on the Fuji 30mm that need to be corrected in CO, but it can read the shift amount from the file like PO XT. The distortion on the Rodie 32 is stronger than the Fuji.
