I know there has been some discussion about Sony's focus peaking implementation on the Nex cameras. It's neat I will admit, but not for me. I would rather manual focus the old way for critical focus. That's when I want to manual focus... The thought occurred to me however, that focus peaking can be a killer feature for something else: chimping! How many times have you reviewed a picture on the camera's lcd, noted it as fine only to realize it was out of focus when you finally reviewed it on your computer? Annoying as heck for me, that's for sure. What if camera manufacturers implemented a "this region is in focus" mode for playback, similar to how they blink clipped highlights and shadows? This for me, would be great. With a quick review you can tell if the faces of your subjects are blinking or not. Or instead something in the background is blinking.
