Why is my canon xti files on full auto mode under exposed? this happens on all full auto modes. My eyes are backed up by the histograms.

The Histograms indicate this is happening. This was purched new from Circuit City and has done it since day one. I feel if they (Canon) indictaed on the box that it won't shoot properly in full auto mode that would be one thing. What can be done about this problem. I had heard that the chip in the camera is not the size they say it is? can anybody give me the true story on this model. Maybe a class action suite might help? Canon has agreed that it is under exposed & has offered to fix it. The problem is I bought this as NEW & it hasn't worked properly since day one.

Hank,

I shoot with an XTi as well and don't have the problem you're describing. If Canon has offered to fix this for free, I would take them up on it. This is not indicative of their EOS line at all in my experience (I have two EOS dSLR cameras that never gave a problem like this). It may have just been an issue with the particular camera you purchased. Good luck.

Andrew, Thank You for your answer. I am glad you don't have the problem that I have with your XTI. I have since been reading more about XTI problems similar to mine. The first person I spoke with at Canon indicated to me that the camera should not be used on full auto mode. I find this unacceptable although appears to be honest.
This entry level DSLR was purchased to introduce me, then my wife and son to the DSLR world of photography.
I have agreed to let Canon check the camera to see if there is a problem. I don't think that I should have to pay full price for a camera that was not working properly right out of the box and quite frankly I am considering selling all my lenses, etc. and going to a different brand.
I feel that when Canon finds that there is a problem with my camera they should give me an upgrade to the XSI and that might keep me loyal to them, provided that there is not some hidden issues with that.
