What are the parameters that define good focus peaking?
As long as the camera and lens can find good contrasty features, any focus peaking will work fine.
I'll stick to bare basics. This is just my opinion.
Strength and accuracy. Being able to adjust the sensitivity of focus peaking to suit the lighting conditions, or to narrow it's response to finer details is
very, very important. Sony has low, mid, and high settings, (Actually, I'd like it if they had more, say 5 levels.) I generally leave it on low because it's finer
and more accurate,but with some subjects, and in certain lighting situations I have to raise it to get a more visible response.
Color.Try using focus peaking that's limited only to white with a scene like like bright sparkles on water or any subject with bright white highlights. It
gets really hard, if not impossible, to tell where the highlights end and the focus peaking begins. Sony has three color settings, red, yellow, and white
and having more than one color choice is crucial for good focus peaking. Of course I would not use red while photographing a fire engine, or yellow
photographing a dandelion. Again, I wish there were more options like blue and green.
Not all lenses are the same. Some of my lenses seem more sensitive and more accurate using focus peaking than others. FP is not a total magic bullet. You
have to practice at it.The technology is fairly new and is bound to improve in coming years. Something I look forward to.
If Pentax could find a way to use FP in some kind of overlay to a prism setup (I think ) they would have something no one else has.
