Re: A57 or A65 for lowlight wildlife?

What constitutes 'almost precisely the same' is going to be best left to the individual to decide.

Objective evaluation shows them to be almost precisely the same in actual performance. The only differences are in processing choice in camera, the amount of information in the images is the same. DxO shows this, as do independent tests.

Anyone claiming there is substantial difference in information in a low light photo from an A57 and A65 is in opposition to objective measurement data. The sensors perform almost identical, as expected from sensors in the same generation.

My advice is to not listen to partisan comment in this forum, but check DPR, DxO and other tests to determine.

DPR is useless for this comparison. No, scratch that, worse than useless since the tests are full of uncontrolled variables and there is not even any clear information on whether light, focus points and exposure are identical. DxO gives an indication which is the closest to objective one can get.

But ultimately the best way to determine whether a camera can do what one wants is to find photos on the 'net where someone has done what one wants to do. If they are good, then the camera can be used to produce them.

Or take pics with each camera in Best Buy or another store and take them home to look at on your monitor.

That's fairly good advice, but again, OOC images will be pretty bad (in different ways) no matter the camera. The A57 loses shadow detail and the A65 shows chroma noise - different ways of showing the information loss from low light.

But taking photos with both and trying to make them look as good as possible is a good way of finding if the camera will match a workflow one is comfortable with. Just remember that all cameras have their own way of handling information loss requiring different ways of PP to get the best results.
