|Sony A7s as a stills camera|
The A7s really is in a different league of cameras. I absolutely love it as a camera to capture my videos and it also has become my number one camera when taking pictures. This really came as a surprise to me as well. The pixels used are much bigger then on "normal" still cameras and each one seems to be working a lot better too. The larger pixels also help to capture more light and thus having the ability to use higher ISO's without affecting the picture quality. The camera is also known as a camera that can see in the dark. And for good reason.
When comparing pictures taken with my former 16MP camera and the Sony A7s at 100%, the A7s wins it every time hands down. Anyone being concerned about not being able to use it professionally and creating large prints can stop worrying. During my trip to NYC I solely used the Sony A7s and one of the pictures I took from a helicopter is now hanging in the living room printed at around 4 x 2 ft and it looks incredible! You can just walk op to it, press your nose up against it (though it's frowned upon) and still see incredible details! I like to take credits for that, but believe me when I say it's the camera.
