This is a common problem with many digital cameras. The shutter or aperture jams and creates a variety of effects. Try tapping the camera on your desk. (Firm, but not too hard) If that fails to help the lens will have to be replaced.

Aperture lever stuck to wide open


On a film camera, the internel electronics determine the shutter speed and aperture. The camera computer figures out a higher shutter speed against the aperture speed. You have a lever on your lens that, when mounted on the camera, will keep the aperture open until you fire. That allows viewing in the brightest light. Then that aperture arm is allowed to close to what the exposure setting the camera determines when you click the shutter. You should be able to take off the lens and easily move the aperture arm and have it snap closed. If it takes a few seconds to close.. then the lens has oil on the aperture blades or the grease inside the lens is bad. These days, unless is it a very expensive lens it's replacement time. Canon lenses will fit any Canon (except Fd) film or digital camera.

My fisheye lens f stop is stuck


You didn't provide the name or model lens, so I can provide generic assistance that applies to many lenses. Hopefully, it will work for you.

Many lenses need to be set to the smallest aperture setting in order to be controlled by the camera. If it is moved off this value, the camera will be unable to change the f-stop value. If it is stuck - meaning the camera can't change it - make sure it is set for the smallest opening (highest number 28, 32, etc.). If it is stuck meaning you are unable to twist the aperture ring on the lens barrel to manually change the setting, look for a small tab that engages the aperture ring. They are often employed to prevent accidental movement of the aperture ring off of the smallest opening.

Good luck!

I have the same problem this guy had: I have a Sony Cybershot 8.1 megapixels. Every once in a while the screen will turn black when I turn the camera on. The display will come up (shaky hand, flash, etc.)...


The camera either has a stuck aperture inside the lens or a bad CCD sensor.

The aperture is the opening that allows light to enter the lens. If it's stuck closed no light goes in, so no display on the LCD and solid black pictures. The way to fix it is to replace the lens. You can try tapping or banging the camera on it's side on your hand or even gently on a table. This might unstick the aperture for a short time, but it will just stick again later.

If the CCD is bad the sensor won't show anything other than solid black, or sometimes purple/pink smeared lines. Again the solution is to replace the lens assembly, or look for a used CCD online and just switch that out instead.

Hope this helps!

Hi

Your lens is aperture is most likely stuck closed and the lens needs to be replaced. If you can see menus but can take only solid black photos then it is either the CCD or the aperture; most likely the aperture.

We have never been able to repair a stuck aperture, we always have to replace the lens on the camera. A CCD can be replaced, but you need a CCD to use and they are only sold as part of the entire lens assembly.

There are online places that will do it for a decent price and there are others that overcharge by way too much.

I know this because I OWN ONE that charges a reasonable price to do the repair! (Google 'darntoothysam')

Just let us know if we can help! Good luck from

Lens is stuck open


We had the same problem with a Casio Exilim. Had been stuck for months...had nearly given up until I saw another post about banging the camera pretty forcefully to get the lens unstuck. I hit it once on the bottom onto my desk(w/ paper and blotter on the desk-so soft), then twice with the back of the camera against the desk. I turned it on and the lens was unstuck!! Immediately took a couple pictures and it seems to be working fine! If the camera may be lost, you've got nothing to lose to try this out...Good luck!

Zoom error


I had sent my camera in for the same issue and they did nothing to help with it. Seems to happen when battery gets low or dies, lack of on-screen battery meter doesn't help. Typically have to manually twist the lens to close it or open it after fresh batteries installed and then seem to fix it.
