Exposure Problem
Jan 8, 2017 09:57:53 #
I have a first generation Minolta autofocus 35-105mm lens that still shoots perfectly in AUTO but overexposes everything in apperture and shutter modes. I believe it is stuck at F4 regardless of where I set the aperture. I have numerous replacement lenses but am interested (curiosity) if anybody has any ideas to correct this situation short of the repair shop which does not make economic sense. Again I have numerous similar and newer lenses so this is basically curiosity and maybe a learning experience.

On the back of the lens in line with the red mounting dot, there is a lever that operates the aperture. See if you can move it with a small screwdriver or similar. It should be closed initially and open as you move it to the right. If it stops anywhere or doesn't move at all, you found the cause of the problem. Check with a local camera shop (or a camera repair shop if you know of one) for advice on repair. I trust Camtronics here in Columbus, OH. Their website is http://camtronicscamerarepair.com/.

The lever you referred moves freely but does not "spring" back to the closed position. Not worth fixing. I have had the lens since 1985 and taken thousands of photos with it so I guess it does not owe me anything! Thanks again.

B&H is showing 3 Minolta 35-105 lenses ranging from $40.00 to $50.00 in condition 8 to 8+. You would certainly spend more getting your's repaired. It's a great lens. I regret getting rid of mine.

If you just don't feel like fixing it, put a variable ND filter on front and take shots by figuring the proper exposure. Just like in the old days!

Great idea.
1st Minolta lens that broke on me. Well it was 30 years old!

I ran into this same thing with my new Minolta (many years ago). Since I was on vacation, I took it to a local camera shop and the clerk freed the stuck shutter. I had no more problems like that over the years I used that camera.

BOY!!! Does that bring back memories of the contortions we did Back in the day. Next I'll see a post of the many uses of a light proof Changing Bag.

You can test your theory with the lens mounted on the camera.
Put the camera in manual mode.
Dial in a slow shutter speed.
Set the Aperture at f16.
Shine a light down the lens so you can see the aperture leafs.
Hit the shutter release.
You might have to set the camera to where the shutter releases regardless of the focus.
Let us know what you discover.

Tried it. Aperture opens all the way. Spring must have come off the aperture lever. Good thinking on your part. Thanks.
