A57: power super pictures, is very good for dark images.
A65: High resolution images noisy, only RAWs useful.
A77: similar to A65
Since I could not decide and the A77 does not provide sufficient arguments for me for the charge, I ordered the a57 and a65.
The a57 confirmed the certified quality clothes is a very good camera.
The A65, however convinced me even more.
Why if everything is noisy?
It's simple: The A65 shoots in bright or out incredibly sharp, high-resolution images (good lens is a prerequisite, in my case SAL16-80Z).
I can also confirm that may make developed RAW images even surpass it and to the best pictures include one with a camera below 1000.
The OLED viewfinder is actually wesenlich better than in the A57 (since I do not use Live View for me very important)
Now for the negatives: The noise is caused by the relatively high sensor from ISO 3200. That is now known but since I'm rather long exposures in the dark or with lens, F = 1.8 work this is no problem for me.
All who have a similar decision problem as me, should consider for what the camera is to be used once.
In mostly shooting in the dark without a flash or with faint lenses A57 is better.
When shooting in daylight and outside the a65 is better.
In the A65 a good lens is extremely important to the sensor really use.
My recommendations are as follows: SAL50F18 Sony SAL1650 f2.8 SAL 1680Z.
