Canon Digital REBEL XT

I have a telephoto lens to put on my camera. When i take pictures with it they are overexposed. They are very bright! Is there some button I need to push or a setting I need for the pictures to turn out? I have used it before and they turn out and then all of a sudden they don't. It is a Canon zoom lens EF 75-300mm. 1:4-5.6 III


question 2

I have another zoom lens Tamron AF 18-200mm 1:3.5-6.3. When I attach this lens to my camera I get an error message -- ERR 99. Can you help me with this one as well?

Hi Paula,

Sorry to hear you're having over-exposure problems with your Canon XT and a Canon EF 75-300 lens. Without seeing the photo and the camera settings you used on your Canon Rebel XT it's impossible for me to diagnose the issue.

It could be a camera setting. It could be a communication error between the lens and your camera. Although your Rebel is over 15 years old, it should be fully compatible with your 75-300mm lens.

It's also possible the aperture is not closing down on the 75-300mm lens. I had this EXACT SAME PROBLEM with the very first SLR camera I ever used. It was a Beseler Topcon and I was shooting black and white film. Although the photos were printable, the negatives were grossly overexposed.

Unfortunately, you're shooting jpgs that are over exposed and there is very little you can do to recover the details in an over exposed jpg image.

I wonder if you can attach a sample photo and give me the camera setting of the photo.

Rebel XT Error Code ERR 99

This is likely a communication error between your Rebel XT and the Tamron 18-200. In both cases, the Canon EF 75-300 and the Tamron 18-200, you should make sure the contacts on the end of the lens are clean. Use a cotton swap and alcohol to clean them as well as the contacts on the Rebel XT. Do it gently and carefully.

The Rebel XT is ancient in digital technology terms, so it's not uncommon to have issues at this point. Feel free to get back to me with more details if you want.

Good Luck. I hope this helps.
