Playing with the toys for Argus Day this past weekend. Along with the C3, I dragged along an original Canon F-1 acquired from a coworker a dozen years ago and never yet used. Replaced the crumbling light seals last week and loaded a half length roll of 3 year old Plus-X. Hey - it worked! It's a tank, I think I prefer my A-1, but if I get serious about it, a different focus screen might be in order -- no split image or micro-prism here -- eyes too old!
