I am contemplating wide angle choices for my Hassy V system paired with the P1 IQ160 back and am writing to see if anyone has experience they can share with the Hasselblad 40mm lenses on a full frame (40 x 54mm) MFDB. I am already using the SWC 38mm Biogon, which I'm pretty happy with (nice rendering, very low distortion) but requires stopping down to f/16 to pull in the edges and corners owing to the symmetrical design of the lens. So, I'm looking for an alternative.
From Zeiss's MTF charts, the 40mm IF version is clearly the sharpest in class but suffers from high levels of distortion, not to mention the cost of a good used copy. According to the MTF charts the 40mm FLE shows significantly worse performance in the corners than the Biogon but I'm guessing that the Biogon is likely doing far worse in reality on the digital sensor than these charts would otherwise suggest. I suppose an alternative would be to move into a tech camera with a Rodenstock retrofocus lens but this would require a bit of a paradigm shift as well as a sizable financial outlay. I might get there one day, but for now I'm focusing on the Hassy V system.
I'd appreciate hearing the thoughts and experiences from the medium format experts on the Lula forum!
Thanks.
John
Edit: I would be using the lens mainly for landscapes and perhaps also for still life images.
