Sony already has inbuilt VR and Autofocus, as a result, you can save a lot on the lenses as you can get old Minolta lenses with the same Sony mount which costs 300mm for $35 and you can get the advantage of both at a price as good as free!

I think if they had an actual value for shutter lag in the A57, took out popularity as a weighted portion of the score (i wouldn't say a Toyota is better than a Porsche because there are more Toyotas), and fixed their viewfinder weight where the EVF gets a "0," the Sony wins handily.

"This site is biased and unfair."

I totally agree with you

The U.S.'s most famous consumer magazine rates the D5100 well below the A57. I can't figure out why you and so many others usually overhype the overpriced Nikons.

Very biased conclusion. The A57 scores higher in 11 areas including in body stabilization and focus points and frame rate, autofocussing during video recording, etc. Very disappointing to see this site showing so much bias.

This site doesn't make fair reviews, they are always in favor of nikon even you can see a big difference between these camera in paper and reality.

This site is totally inclined towards nikon..

Arbitraging (4:31 AM, May 10, 2012)
What kind of scoring is this when 6 of the highest points of the A57 categories are 0? Couldn't you figure this out some of these categories? And how is it that both cameras get the same score for shooting different video framerates? The higher framerate should get the most points. Did you forget to account for the fact that the Nikon can't autofocus while shooting videos? This site is biased and unfair.
