The Leica M3 I picked up last month needed to go off to the doctor (the esteemed Youxin Ye) for a CLA. I just got it back, cosmetically it looks the same (because it was in near mint condition to begin with), but it operates so much more smoothly than it did when I got it. I’m taking it to the SF Instant Photowalk this Sunday (along with the Polaroid SX-70), and I absolutely cannot wait to run some Tri-X through it.
