Look at SONY's A77 and compare it to the Canon 7D, which we own... Yes the 7D was a great camera when it was released, but Next to SONY's A77, it simply doesn't measure up at all... I'd hate to switch, but I'm contemplating switching to the A77 and the A99 when they become available
You're surely not complaining that a 2 1/2 year old camera is eclipsed by a rival's new model? I was going to take the mick out of you but people flitting from one brand to the next every time an improved model is released ensures that Canon continues to raise their game.
