I'm know I'm seeking an objective answer to a subjective question here, but I'm wondering if anyone has shot with all three of these and what their thoughts are on how they compare in different fields (sharpness, tones, durability, functionality, etc.). It figures that as I finally complete my Hasselblad system, I'm looking into Rollei and Rolleiflex systems. I know the only real way to do this is to borrow or buy them, but considering I live in the most Northern metropolis in Canada, it's unlikely that there's people up here that have that equipment to trade for a couple weeks and I don't have thousands of dollars for experiments. Any advice? Is there a good site even that compares and shows examples of different lenses and films? I know photosig.com has some, but no one there shoots film anymore, so the examples are never updated. I know there will be lots of comments on this one, so thanks in advance....Jordan.
