Some said even the expensive Hassy lenses don't resolve very well above 50MP
Hasselblad has a camera capable to output 200 megapixels shots on offer (using multiple exposures). Same lenses.
However I do wonder why the HCD lenses are not capable of producing full frame image?
They have been designed for the slightly smaller Kodak CCDs of the time. It is not a real problem though, it is only 3 lenses and even then they may be used on the larger sensor, the extreme corners will just be a bit less sharp. In practice, by lens:
-the HCD 24 mm may be suffering the most, but 24mm is extremely wide and I think that most people buy that lens to use on the HTS and then it is not a problem
-the HCD 28mm loses a bit in the very extreme corners, but not that much
-the HCD 35-90 covers the full sensor at 40mm and above.
(This is only hearsay, as I have a Kodak sensor on my camera.)
But since you said you are interested in portraits, the HCD lenses are of no interest to you anyway...
I know there are a lot of used glasses around but how does number of clicks affect lens performance? How many shots before a LS lens becomes useless?
The leaf shutter on H lenses is rated at 100K exposures. It can be exchanged by Hasselblad for a fixed price listed on their web site if it fails.
