Re: Sony A57 - Short Sci-Fi Movie Trailer

Thanks!

The peaking function is excellent. The autofocus function is good. For photos, it's probably excellent, but for videos, if you want usable footage, you cannot deviate from the user's manual at all, really.

I was really hoping the autofocus would work like some of the sample videos of the VG20, which will hold a tight focus on a subject even when other objects move in front of it. This one won't. Also, if you set the camera on autofocus, you lose depth of field. The F-stop resets to 3.5. I saw a post somewhere that one of the old A65 firmware versions retained manual f-stop even in autofocus, but later firmware upgrades dumped that feature, and the A57 certainly doesn't have the feature.
