Getting 1/1000 second on a horizontal scan fabric focalplane shutter can be a tricky business. The Exakta Varex models are particularly difficult but sometimes one gets lucky. Everything has to be just right. I refer to cleaniless, spindle friction, lubrication and of course the correct spindle tensioning and determination of starting position and curtain overlap. As Rick says - a film-chip foreign body in the wrong place (aren't they always?) can be enough to stuff things up. If you are not familiar and experienced with focalplane shutter work - you might choose to live with the shortfall if 1/500 sec is OK. Hope this helps ... a bit. Stuart Willis |
