bronica sqa 1/500 sec shutter problem

[wilfbiffherb]

hi,

ive just noticed that when i fire the shutter on my sqa when set at 1/500 sec the shutter stays open for about 2 sec. the shutter seems fine on other settings. does anyone know why this may be happening??

As you probably know, the shutter is in the lens which could be the problem. Have a look here:

This seems quite strange. 1/500 is the default speed -- purely mechanical -- and should work without a battery. All the slower speeds involve some sort of electronically controlled interaction. The electronics are in the body, and as CGW said, the shutter is in the lens. Trying another lens might help isolate the problem between lens and body. That is, it could be some sort of switch malfunction that the 1/500 setting isn't switched correctly in the body. You might try removing the battery and see if the camera fires at an obviously fast rate. If it does, that would point toward the body as the problem, if there's no difference, it suggests the lens has a problem.

It seems odd to me that a slower speed like 1/125 would work if the shutter was mechanically hanging at the1/500 setting.

i tried my 80mm lens and its fine so looks like its a lens problem which is a bit poop as i only got it a week or so ago. guess i should be thankful that the other shuteer speeds work (at least they look like they do)

I'm not encouraging any sort of amateur neurosurgery with this but have a look here for what's what regarding a Bronica S/PS lens' innards:

If the man in the street could easily repair complex modern electro/mechanic cameras and lenses effectively there wouldn't be need for professional camera technicians.
