What is better, this or Sony A57?
Specs-wise, I think the A57 wins. I have never used either camera though.
Some points I prefer on the A57:
- bigger APS-C sensor
- in-body image stabilization (G5 needs lens to have IS)
- external microphone option
I still like a few things with the G5 more:
- the flip out screen on the side instead of the bottom
- smaller size + weight
- this packaged price
