I recently rescued a Minolta Hi-Matic 7s from the thrift store. It's in beautiful cosmetic condition but has a few quirks, and I'm wondering if it's worthwhile to open up to clean or if that is best left to "the pros".
When I first got it, occasionally the shutter would fire when the film winder was used. This only seemed to happen at 1/30 and seems to have gone away.
The aperture opening seems to have linked itself to the shutter release. Not sure how better to describe it, but if you set the shutter to bulb and slowly depress it, you can see the aperture opening (and then closing again) as if it's attached internally. Not like a hard linkage, more like something sticky inside.
Is there an easy fix? I don't want to delve into the innards unless I know I can get back out again.
If this needs further explanation I can film a short movie clip to demonstrate.
Thanks!

There are two sets of blades. On the one hand what you describe is the usual opening function of the set of aperture blades in the auto mode seen from the film chamber, with no battery in the camera. The shutter blades, on the other hand, can be seen from the front, and with the shutter set to "B" they should open when the shutter release button is fully depressed and finally close again simultaneously with the aperture blades when said button is let loose again. |

OK, thanks for the info. I put a (1.4V zinc-air) battery in it; now it looks like the light meter is working. and the auto aperture is too.
The shutter is certainly working properly, snapping open quickly and closing quickly with the speed selector on bulb setting.
I think I will assume the best and run a roll of film through it in automatic mode. The manual modes appear to work (by my reckoning), and the automatic modes shouldn't really be used for anything slower than 1/250 anyway. Hooray manuals! |
