Hi, everyone.
This question is for all you extremely knowledgable optical people. Lord knows there are
more of you on this forum than is at an opticans convention. Unfortunately I'm not one
of you.Not long ago one of my favorite lenses (Ektar 203) suffered a fatal shutter
failure. Two weeks later at a local camera show I found the same shutter,a flash
supermatic with cells,and it worked.I got it very cheap because the front element looked
like it was cleaned with steelwool. It was bad.The rear was just passable. But,my only
intrest was the shutter.The next day I tested the shutter.I made five exposures on
type 55 film at five different speeds and stops. Negatives were fine and confirmed the
shutter was pretty much in agreement with my light meter. What I didn't realize is
when removed the cells from the two shutters I inadvertently put the same bad cells
back into the working shutter.A true senior moment! ( I did have a phone call while I
was doing this.) It was back to the darkroom to examine the negatives again. They
were good, no flare, tack sharp, and nice contrast.
I would very much appreciate any comments on this.
Thanks, Joe A
