The Sony A57 can shoot full-resolution 16.1 megapixel pictures at up to 12fps whilst maintaining continuous auto focus and auto exposure, an incredibly fast rate for such an inexpensive camera.

To be honest, super megapixel just hasn't been enough to prompt me to buy anything new.

Nikon and Canon make excellent products in the DSLR market, Panasonic does well with its micro four thirds system and Sony's stronghold as underdog may well change with it's SLT line of semi-transparent mirrors.

When its APS-C sensor is combined with a reasonably fast lens, the EOS 650D offers the opportunity for creative use of shallow depth of field, something that will be a revelation to anyone used to shooting video with their smartphone or compact camera.

Size, it feels just right and comfortable in my hands.2- Bright 3 inches pivoting screen, that you can actually fold back when not using, thus protecting the screen.3- The EVF is excellent, bright and captures all the details.

The camera overall is pretty responsive if you only use the view finder.

The a57 feels solid and heavy, as one would expect.

I have completely changed my mind, it will be worth carrying around a little extra weight on vacataions, etc. because of the quality difference.

The shutter-release has a definite half-way point, with the focus points (a choice of 15) rapidly illuminating green in the viewfinder and a confirmation bleep signaling that focus and exposure has been determined and the user is free to go on and take the shot.

Whereas the 600D offered only one cross-type AF sensor in the centre of the viewfinder, all nine AF points of the 650D are of the cross-type variety.
