Yes I have assigned a function button to focus peaking and it works fine with my m4/3 lenses but not with this specific lens. The image that I am trying to have it function is at a distance of approximately 30 ft and I am thinking that the dof is so narrow that that is what is causing the problem. I will try at a couple hundred yards to see what happens.

I see. I wasn't trying to be a wise guy. I just didn't see that mentioned in previous posts.

I have been following this thread because I have for a long time thought about getting one of the reflex lenses too. There are a few around reported to be very good. I hope if you find a solution to this dilemma you will keep us up with what you found. What a compact long distance reach on u4/3!

To take a photo of what I saw should have been so simple...
