Some thoughts on SX-70-I have three SX-70's- the Alpha 1 that my mailman gave me, and I reskinned with new leather, and 2 beautiful Sonars, one that was found by my Mom at a thrift shop for $4, and the other that I bought at a pawnshop for $40. They are beautiful cameras. I think Impossible is driving prices upward, and the appeal of restoring and shooting with them is undeniable. The classic Land Camera series cameras are tanks, more reliable, and do yield a better looking print. But if you want to "experiment", sometimes you can get an impossible print that looks like classic SX-70, and sometimes not. The newest formula, PX70 Color Protection, is beautiful, but does have its quirks.
