can't believe i'm becoming a nikon person after years of sticking to OM and Pentax 67
a nikkormat EL with (all pre-AI) 20mm f/3.5, 28mm f/2, 55mm f/1.2, and 85mm f/1.8. i'm using it because it's the only 35mm autoexposure SLR ever made (afaict) that has M sync at all speeds, for flashbulbs.
technically i already had the body and 85mm, but they were languishing without me knowing how much i'd enjoy using them
M sync as in "manual"? (I know a bit of photography but NOTHING about flashes)
cool lenses it seems owo
as in "medium," it fires the flash 20 ms before opening the shutter, to give the flashbulb time to start burning
