    Bronica 80mm PS problem

    Well, today I am annoyed - it appears that my 80mm PS lens has developed a fault.

    When shooting at 1/500th of a second, I am getting long (& inconsistent) exposures. Sometimes I get a fast speed, other times I get a few seconds. I have tried most the other shutter speeds - those that I can easily measure appear OK. The faster shutter speeds sound quick. It just seems to be at 1/500th. I have tried my another lens on the body and this appears to be OK.

    Has anyone had this issue before? Could it be something as simple as a bad connection?

    Cheers

    (BTW, this is the 4th piece of camera equipment that I have had an issue with in the last 6 months - I tell you, the whole lot is going to end up in the freaken bin.....)

    Well, I attacked the damn thing with a dremel this arvo - seriously!

    OK, not quite that bad. I polished up the pins using a dremel & polishing pad and it seems to be on the improve. I was a bit fearful, though, as after I had finished the job, it wasn't working properly at all. I then played with the T switch and it came good. I have just done an aproximate test using my DSLR in the focal plaen and a light source to test the shutter speeds and they look pretty close. From my eyes, I think @ 1/500, its a small bit slow - maybe around 1/400th.

    I'll run a roll through it during the week and see how they turn out.

    Cheers

    Actually - a bit of thinking out loud here - Could it be dying or near flat batteries that's causing this?

    Sounds like it could be battery problems...electronics in cameras...always a problem at some stage, that's my experience. The cameras that have never given me problems...my Rolleiflex, Minolta Autocord, & Mamiyaflex C330. ......all totally mechanical.

    AFAIK 1/500 is the one mechanically timed speed on the Bronicas. With no battery it should shoot at 1/500. So chances are the problem is mechanical.

    I had similar problem with 50 S lens giving me inconsisted speeds - I've opened the lens and cleaned iris and shutter blades with isopropyl alchohol and also cleaned lens contacts a bit. 5 minutes job solved the issue.

    Canuck, if you have some limited experience, right tools and patience then it's not that difficult, not as, say, Leica-R lenses or Nikkors with CRC.
