Did you ever figure out the problem with the over heating? Was it just a defect or something?

The Sony A55is FAR superior to the T3i (having tried both). Get the Sony and don't look back! This rating system is biased because it is not as popular of a brand.

I know many people will tell you Canon makes better Cameras but Sony is actually much better. Dont get me wrong Canon cameras are fantastic but sony has better ones specially with the carl zeiss Lenses.

I purchased the T3i but when I actually compared it to my friends A55 I really noticed the difference. In my point of view the Sony is much better in picture quality and futures. I returned the Canon and got my Self the A55 and LOVE IT. Its an amazing camera and does everything I want.

This rating system is silly.  The a55 outshines the T3i in almost every aspect.  I assume it gets -25 points off the top just because the name is "Sony."

I bought the Sony a55 and it went back to the store in 5 days. I'm not a professional but I know what looks good. The canon t3i offers remote capture with a laptop and Sony does not. The images seem to be better on the t3i too. Sony did have its advantage with using my Minolta lenses that I have. But for me I need the ability to work the camera with my laptop in remote capture. This is Just my opinion. I think the viewer on the Sony is awesome (better than the picture). Where the viewer is great on the canon but the picture is awesome. One more thing. The way the screen open and tilts is also better on the canon and does not interfere with the tripod. But the Sony does. Again for me I need the tripod for my shots. The Sony is lighter. to carry. Hope this helps someone with their purchase.
 
Confused (11:17 PM, August 19, 2011)
I'm told that professionals only use Nikon and Cannon. I have a Sony point and shoot and I love it. I'm obviously no professional, but why don't these photographers use the Sony cameras? This comparison seems so lopsided to the Sony, but every store I go to they don't even mention this camera, they bypass it and go to the Cannon or Nikon cameras even though they are right beside eachother?! HELP!!!

How does popularity determine the better camera? Clearly the a55 is superior, regardless of the verdict given here.

Hey, i had just bought A55: pictures were just stunning; 10 frames/ sec. is awesome, just shots well with my son's soccer game, not missing any good moments; handheld twilight is just great, i love it. Whatever the cons are, pretty neglible for personal use, or for an entry level camera.

i have the a55 and it overheats after 10 minutes of video shooting even with image stabilization and gps off. then you cant shoot video for more then 2 min

There is no questions for this competition. I will choose SONY Alfa 55. But I am just waiting an official sales statement of Sony Alfa 77 in order to get '55' with a low price.
 
Cuyo (8:28 PM, May 28, 2011)
I'm buying one of those and I think that will be the Sony...

are you sure, i would rather have continuous AF (especially as good as the sony's) in movies than 24p. 
 
Avatar for Snapsort Snapsort (1:18 PM, April 25, 2011)
The Sony is a great camera, but the Canon has more lens options and a better video mode.

Which one should I buy? They both look cool.
