My wife's camera doesn't always fire the shutter at the selected speed. Out of a few rolls shot an a recent trip, only a few frames on each were exposed. I tried firing the shutter many times in a row and found that most of the time it fires accurately but then goes to default mode(1/60th i guess) for a few shots before returning to the speed set on the dial. The battery was fresh and no prism was attached for this tests.
-Does this sound like a LENS issue since this 75mm lens contains the shutter or a BODY issue?
Neither aren't worth getting repaired since I can get a replacement for about $50
I made an earlier post about the camera eating batteriesthere was a url link here which no longer exists)
Sounds like a battery issue to me.
Contacts more specifically.
It could fit tight 'most' of the time, only to be knocked out by mirror slap or something of the like, thus making it read as 'dead', and then maybe it just wiggles its way back in.
I had similar issues like this with my Konica FT-1, though never with my Bronica.
Make sure the battery contacts are good and tight, not just that the batteries are fresh.
thats correct if the battery is dying or dead and not supplying power to the lens the shutter speed always fires at I think 500th of a sec. at least ive been told that before but ive never let it happen.
