Seems to me there are a lot of meaningful advantages of the A77 over the canon and most of the canon advantages seem minor. So why is canon rated highter? Sony has the same sharpness with an apc format that the canon has with the full frame. Sony takes 3 secs to start over 1. BFD, Canon shoots max 3fps which is 1/4 that the sony shoots. Through the lens viewing versus prism saves power? OK but the sony shoots from trigger push to shot in .09 sec vers a couple ice ages for the canon. Is 92 vs 125 lenses available really something to worry about? How are they counted? Old Minolta's too? I'll give the canon pluses on low light noise but the sony has algorthims to significantly reduce noise in low light that did not seem to be evaluated. Seems that the canon is not slightly more expensive either it looks like it costs 2/3 more $1K versus $1.7K. Sure I own an A77 but I did after comparing it to the canon. Frankly, there was no comparison. They are both good cameras but the A77 has the features and performance way over what the canon did. One thing I really liked was the image stabalization in the camera. I can use older AF lenses and they are stabalized. No so with the canon where the image stabalization s in the lens. Maybe that cuts down the number of useful lenses available. Anyhow They are both good cameras. but I think the ranking and what the authors consider important i stretching it a bit in favor of canon characteristics when it comes to weighting the ranking metrics. To me the points should be reversed at a minimum and maybe a few more added to the sony. Based on extensive testing and shopping I give it close to 90.

Hey IWilliams
You are right the viewfinder magnification is 1.1x. Snapsort takes the cameras crop factor into account when calculating the cameras real viewfinder size, this way you can compare cameras with different sensor sizes. Check our out article on viewfinder size if you want to know more.

You have the wrong viewfinder size for the a77.  It is 1.09x, not 0.72x.  That makes it MUCH bigger than the 0.72x viewfinder size of the 5D MkII.  See this site for verification:  http://www.dpreview.com/reviews/sonyslta77/page2.asp

lol you are funny.

Seriously? 1 stop better? Looking at the DPreview tests (which post ACTUAL pictures backing up their claims) I see slightly over 2 stops. Not to mention a ridiculous difference in IQ. Even when compared to a 50D, this camera can not compare in sharpness.

Think I'm being a fanboy? Check it for yourself.
