Sony A560 or Canon EOS 600D?

I think Canon will make a better camera. Most of the people will recommend Canon. i didn't have any DSLR camera though, but many of friends do and many prefer Canon over Sony. Beside looking at the Mega Pixel, you should also look at the ISO value. it determine how good will your night shot will be. The higher the better the quality of the picture. If I'm not mistaken, Canon have better ISO value compares to Sony at the same price. My recommendation, unless you want to spend a lot of money on camera you should buy Canon. Cheaper than Sony but with better specification. That's just my opinion though.

Well I may be able to help you. What is going to be your main focus for photography with your camera and will it be as hobby or professional. If it is hobby I would say the Canon is just fine but if you mean it for serious business Sony would be the way to go between the two. I hope this helps you to decide.

I'd say canon, but that's mainly because I have a canon camera myself :-) However, unless they've changed the bodies on the 100series, beware of dust. The one I had got dust inside it and it was really tricky to get rid of it. It's not so annoying if you have automatic sensor cleaning, but still not a 100 % dustproof. One of the reasons I got a more expensive camera, but I take a lot of pictures in dusty places. (show jumping competitions for example)
