Originally posted by StanT Not sure what this is, does it increase the LCD display image sharpness on the camera?
Using the menu, go to Camera 1, then "Contrast Detection AF", and in that sub-menu "Focus Peaking" which can be turned on or off (ON for the feature).
What this does is places a high white along edges that are sharply focused (derived from a high-pass type function). It makes the LCD display appear somewhat sharper, but more importantly, it accentuates a well focused object by outlining it with a thin white highlight. This function only works for liveview and also applies to liveview magnified images so if an image is magnified to X16 and focus peaking is applied, it should make for fairly accurate focusing. Furthermore, it's a function of the sensor itself, so it doesn't depend on any autofocus estimation or have any AFerrors. The downside, of course, is that it won't work for the optical viewfinder and you have to use it with the LCD screen.
If I'm doing critical focusing, I use liveview, magnification, and FP (with manual focus). Sometimes, due to the depth of field of some lenses, and the character of some objects, you have to guesstimate since the FP will show those enhanced edges over some focus range of the lens. I usually rock the focus and find the two points where the peaking disappears, and then focus half-way between those points.

Originally posted by disasterfilm I think he's referring to focus peaking. It's a colored "edge mask" that makes high contrast parts of the image shimmer in Live View to indicate areas that are in focus. You can select the color of the effect from a small palette.
Hmmmm, I guess I never found that small palette. How is it accessed?
