When I look through the viewfinder of my Canon Rebel XTI, the AF points are blurred. I noticed a small halo when focusing(I had it set to focus with the middle point). I went to change the focus points and had them all lit up at once and the halo is around the 3 bottom points and the top point really badly and the others only slightly. I cant find anything on the net about it. I can't see that its causing a problem with my pictures, what should I do? What's causing it? I'm afraid to attempt to clean anything. PLEASE HELP!!

Can you use Sigma lenses on Canon cameras?
Since Sigma lenses are made to be fully compatible with Canon cameras, they are backwards-compatible. This means that you can use a Sigma lens on a Canon DSLR camera. Similarly, the Sigma cameras are backwards-compatible with Canon lenses.
Macro adapter loses the AF feature.
Then you learn, when everything works fine, dont mess with it! Have a look at the gold pins that rely the body to the lens. Also check that your lens manual switch focus is engaged... Try a friend lens to see if its your cam or the lens...
This may not be the same as your issue, but our AF stopped working as well. I tried all the recommended fixes - removing the card and battery, recharging the latter, removing the lens and cleaning the contacts, etc. None of those things worked. However, I then switched to MF, requiring me to turn the barrel, and I realized it was stuck and just needed a little force to get unstuck. Might have been the humidity. Anyway, our problem was solved - AF was back to normal after that.
I had this problem awhile ago - you must have accidently adjusted the focal area - it is sooooo easy to do without realising it. Here is what I was told: **************************
Most likely, you have changed the AF point, which only takes effect in the creative modes (Manual, Av, Tv, P, etc)
There should be a button on your camera that has a grid like pattern above it, like - - - - - - -
so. press that, look through the viewfinder, and move the shutter or
rear wheel, you should see the different AF points like up in red, and
as you turn different ones will light up, and eventually all of them.
also, you can look on the screen on top (or back, if its a rebel) and
it will show you which ones are selected while in that mode, instead of
looking through the viewfinder.
