              seriously...I mean you're talking about cameras...a machine we use to captures PICTURES...and somehow the second-best rated camera by dxoMARK loses almost every comparison...?????????
              I use an Alpha57...a tiny mice of a camera when compared to other giants but I see my ease of work and a 5D user's struggle with video run-n-gun shoots...focus peaking...1080p @ 50fps (I'm from PAL country)...seriously...I can't wait to upgrade to an A99 or an A7R one day...

              "Optical viewfinders save battery life and are more detailed"
              I would say, they'll stop saying that when they're at an indistinguishable level of detail. The day's coming.

              Agree with Adam and when will Snapsort stop posting 'Has an optical viewfinder' as an advantage as it is not!

              UUUMMM I believe you may have mixed up the overall winner.... clearly Sony has better ISO AND better Image quality, that alone is a winning factor..... not to mention it cost less shoots Full HD video @ 60fps oh and built in WiFi, 100% FOV coverage... Sony blows the extremely outdated Canon clear out of the water with user options like focus peeking & color histograms. Snapsort must be biased or something because this doesn't add up??? this is just silly.
