bronica shutter problem

grokglock · Mar 3, 2015

I am having an issue with my etrs where the shutter in my lens will remain open intermittently. It happens with 2 50mm lenses i own. I don't know how to determine whether both lenses are bad or if its a bad body.

I know these problems are fairly common but haven't been able to resolve mine. Any help is appreciated.

I have changed the battery and the problem persists however without battery the shutter seems to work fine (1/500 sec)

Does it happen on all shutter speeds or does it happen on 1/500th only?

I had a similar issue with 2 lenses for my SQAi, where they were slow or sticking on 1/500th. This speed is the "default" speed that doesn't rely on any of the electronics to get them right.

In the end, the lenses needed a CLA. Depending on where you live, the prices could vary to get this done. The alternative (& in the end probably cheaper) is to buy another couple of second hand lenses. I went with the CLA, because in the end I hopefully have some gear that will give me good life.

It sounds like it needs a CLA. www.keh.com does repairs and CLAs.

It happens at all speeds, the shutter fires and remains open. The problem does not happen without the battery and yes the camera defaults to 1/500 without a battery.

Its happening on 2 of my 50mm lenses which makes me doubt the camera body itself.

Probably I`m wrong
What about the time exposure lever on your lens - is it in right place ( to the right side looking from the body towards the lens) ?

Have you tried firing the shutter with the lens off the camera (I assume that these are like the SQ lenses)?
