Just got a medium format rig the other day on eBay for cheap (roughly quarter-price - it's amazing what deals you can find now that everyone's going digital). Took some test shots and discovered that the film back is -- gasp -- leaking light on the crank side. (Look in the lower left-hand corner of the frame for a washed out area.)
Time to call Hasselblad for that $7.50 seal replacement kit.
Anyway, can't wait to get it fixed and start blowing the negatives from this baby up. Should look spectacular in mural-size proportions. To give you some idea of the resolution of 6x6 film, it's roughly equivalent to 100 megapixels. For $1.99 plus $12.00 per roll for film, processing & proofing, I'm in business.
