              This website seems really ANTI SONY, As many other sites where Nikon and Canon are always given extra points just for the brand or the lots of people giving bad reviews to Sony cameras, Sony has always been more innovative in other fields and end up being the best, they are catching up now with cameras. I bought a Nikon 7100 against Sony A77, based on the review here and some other guys in youtube who really seemed to love Nikon, then after a week turned Nikon back and got the Sony, best decision ever. It is true that Nikon 7100 takes better quality pictures ( visible at 100% size and JPEG only ) and that Sony is a noisy camera even at low ISO, But if you shoot in RAW you will get very similar results with both of them. Also the battery of the Sony is an issue. So as a traditional camera and for pure photography maybe Nikon 7100 is better. Now 12fps of the Sony is just awesome, the AF is super fast and in continuous with the face detection very very accurate, then the Electronic View Finder (EVF) is the best, you try it you never want an OVF, you can see EVERYTHING before you shoot, a lot of info, the changes you are making...so OVF should not be an adventage anymore, sorry. And I hope all cameras get an EVF from now on. The focus peeking feature is amazing, allows you to manual focus super fast and accurately, and the kit lens 16-50mm 2.8....Best Kit lens you can get with a body and weather sealed. The LCD of the Sony can rotate and move to many positions which for video and composition is great, Nikon nothing. And the thing that I love the most, Sony video is really good, with the fast autofocus, Nikon video just sucks, sorry. So the PROs of the Sony A77 are many more than CONS campared to the NIkon. So unless you are going to shoot only JPEG in low light conditions that you need a high ISO and you don't want to edit your pictures later, or you already own some Nikon lenses...Sony is better.

              just that it is larger, brighter, ability to review Photos directly in viewfinder, detailed info display inside EVF.. and yeah they can work in dark. you don't have a reason to hate EVF. It's very clear that you have either used EVF in a low end camera or have never used EVF at all. Just use a High res OLED EVF for sometime and I bet you can't go back to conventional OVF.

              No, it doesn't "suck", as you so eloquently put it. Quite simply, if you haven't used a Sony EVF for an extended period, then you cannot judge. I have, and it's brilliant. Overall, the Sony A77 is a fabulous camera.

              > in the D7000 review you rated OVF as a plus
              yes, evf sucks

              Snapshot previously rated the Nikon D7000 @ 69 vs Sony A77 @ 66. Sony made the D7000 sensor. The D7000 was 16mp vs A77 24mp. Not sure how you rated the D7000 over the A77.

              I sold my Nikon D7000 equipment and switched to Sony A77 with Sony and Zeiss lenses. Nikon makes very good lenses and traditional camera bodies. Sony EVF and SLT technology surpasses the traditional OVF and SLR technology, but in the D7000 review you rated OVF as a plus.

              For the D7100 you give a plus for in-camera HDR, which Sony has always had in A77. Sony made a great decision to have SteadyShot option to adjust for "camera shake" in the camera body. I believe the reason Nikon decided to put their "Vibration Reduction" into lenses years ago was a marketing decision.

              Nikon appeared to recognize their technology weaknesses when they chose Sony to build sensors for the D800 and D7000.

              Your review would lead many buyers to simply buy the Nikon D7100.
