I bought a used Hasselblad 500 C/M last week. I took my first shots last week-end (this is my first medium format camera, and I had to learn how to load it and process 120 format roll film). Today I installed an Epson 3170 scanner capable of scanning medium format negatives (at the highest quality settings of 3200 dpi at 48 bits, this yields 52 megapixel files weighing 300MB each!). The quality is simply amazing, even more than you could expect with the 4x larger negative area than 35mm. Here is a preview scan of one of the shots (the inner marketplace courtyard, Ferry Building, San Francisco), and a 3200 dpi blow-up of the upper left corner of the frame:
