It's actually amazing that in this digital age, we can fill 6 pages comparing Hasselblads and Rolleis. I love my Rollei (an oldie from the 50's) but I gotta admit, it is getting damn hard to focus on that silky-smooth focusing screen. The Hasselblad is no easier, but I have the option of my 45-degree finder. Wish I had a split-image thing on the focusing screen of the Rollei.
You can get custom screens for Rolleis if you want - even in the older cameras, but you'll need professional installation in the pre-F models. I'm planning on having bright screens put in both of my E's soon.
