    I've been getting this type of glare in some of my photos. It's mainly in low lighting and has occurred even with different lenses. Also, it's normally occurs when the ISO is 200 or higher. Is this normal?

    Here's an example:

    Taken with my 50mm 1.8
    ISO 1600
    f 1.8
    1/200 s

    Thoughts?

    I think you must have some smudges or dirt on your lens causing this. I had a similar issues, and i just cleaned my lens and the glare was gone.

    That doesn't seem to be the problem as I always make sure they are clean before I shoot.

    ISO 1600.

    it's called banding I believe, and with crummy sensors (like the one in your XT, and my XTi) high ISO settings equate to banding in low lighting situations. you'll be better served using a slower shutter and lower ISO... or getting a better camera.

    The OP says it happens at anything above ISO 200, though. I agree with the comment about a lens hood. It might make a difference.

    I've never had lens glare that looked like that.

    Are you talking about the purple lines running across? If yes, how many shutter actuation do you have on your camera?

    I'm saving for a 40D :mrgreen:... just wasn't sure if there was something wrong with my camera.


    Yes sir.. I'll have to check. I bought it used so I'm not really sure.

    It could be caused by hom many shutter clicks the camera performed. For the XT I believe its 50,000, after that you get noise and banding problems, even at low ISOs

    Considering the uniform lines that they make I am also thinking that this is a camera sensor problem and not a lens relaited one. I don't know about sensors dieing after so many shots (I know the shutter can die certainly but not the sensor itself unless you abuse it with a lot of very long exposures - typically running into many minutes and often the sort of thing you only do for astro photography).

    First stage I would recomend having the sensor cleaned to make sure its not some smudge/mark on the sensor itself (if you have had it cleaned recently that would explain things). If the problem still remains then it could very well be sensor failure
