Difference between a Hasselblad 40 CFE and 40 CFE IF
I am considering one of these lenses (the former used and much cheaper). What are the differences as the Hasselblad site PDF's don't download correctly on my computer.
If after many years of service, my 200 series Hasselblads fail and cannot be repaired, what other cameras, if any, can I use the FE series of lenses on?
The 40mm CFE and CFE IF will work on any Hasselblad 200 or 500 series. It has a leaf shutter as well as the electronic contacts for the 200 series. I have a CFE and it is a great lens.
The IF version has better resolving power.

And the performance of the IF-version in the center itself is even a bit better as well.
But that comes at a price: distortion has more than doubled (max. 3.6% of image height), compared to the non-IF (max. 1.5%).
The IF was advertised as a "digital" lens. And yes: if you can clip away (like too small sensor do) the bits where distortion really is terrible (the edges and corners of the frame) and keep the near perfect center performance, it would be one of the very best lenses ever made.
For normal, "full frame" film photography, i think the non-IF version is preferable.
