Hi folks

I recently picked up some dirt cheap Panatomic-X, it's the Aero version in 15ft lengths, 70mm perf, so ideal for my Mamiya 70mm backs I use with my Century and Speed Graphic 23s.

It expired in 1968, but I suspect it will still be fine.

I mostly use Microdol-X 1:3 and I read it was ideal for Pan-X.

Before I shoot some of this stuff, I would like some tips. What speed should I rate it at, given the age? I usually rate at half box speed if developing in 1:3 M-X as I love the tonality I get.

Is the Aero version any difference to regular Pan-X?
