    Default 14-54 locked at smallest aperture

    My 14-54 lens, first model, is locked at smallest aperture. This manifested as a dark view-finder when the lens was on my E-510. The same thing happened when I put it on my E-300. Both camera bodies behave normally with other lenses. My conclusion is that the lens needs qualified attention. I am posting here on the off chance that someone might be able to offer another solution.

    I agree that it sounds like your lens needs help. I suppose you already tried shaking it (gently) and other such things (soaking it in water for 3 days, etc ).

    I remembered that there is an option in the menus (at least for the E-520) for a lens Reset when the power is turned off. I checked it, and unfortunately it resets the focus, not the aperture. However, you might try changing that and powering it on/off a few times. I'm just trying to think of something that might "goose" the lens somehow.

    Thank you, Rich. The E-510 and the E-300 also have the Reset Lens option, and of course it has no effect. I tried many methods of goosing when the problem cropped up, including a full reset of the camera body. At the time I had just one body and one lens, so I had to suspect both.

    Pencil eraser on the contacts. I had a 40-150 lens giving me problems on a couple of E bodies. Rubbed the contact on both bodies and the lens with pencil eraser. (do it with the body opening pointing down to keep particles out of body). Problem disappeared... apparently a contact issue. Happened a couple of weeks later. Just did the lens this time, because it would still fault on either body. Problem gone. Did not come back in two years. Suggests body to lens contacts needed cleaning. Standard pencil eraser... no eraser with grit in it (no white ones)

    Thank you, saichiez. In the past I have faced trouble caused by dirty contacts, but this time the eraser trick did not work: the lens is permanently at minimum aperture, even when not mounted on a body.

    Had this exact problem and it was dirty contacts - cleaned both the camera and the lens...I used a Q-Tip with a little film cleaner or alcohol. I chose film cleaner because it doesn't leave a residue...but you could also spray the Q-Tip with a little electrical contact cleaner...

    If that doesn't work then I suspect it is time for a trip to the Oly Doctor...

    Good Luck!
