This looks pretty nifty--thanks for sharing it!

But when you say "DSLR", do you mean that it won't be of much use to us PEN owners?

From what I gathered, it can show you [back] or [front] focus. And Contrast Detect doesn't have that problem because it focuses off the sensor, not a secondary sensor in the camera well under the mirror that receives an image from a sub-mirror behind the main mirror

DSLRs use Phase Detect for focusing.

Some DSLRs have a way to adjust this via a menu open. My Pentax K20d did for up to 20 lenses, Others also have this option.
