When I first acquired my refurbished Oly E-P5 camera body I was amazed at how instant the Auto-focus was on the Oly 60mm f2.8 macro lens (m43). Setting the focus dial on the lens to its' full range I was expecting a little bit of focus hunting (as was my experience with the E-M5 camera). Instead what I got was instant focus lock from 1:1 to infinity. I am still amazed at how these two seem to work so well together in not only the instant focus acquisition but on the super sharp images they produce together. Just got a Nikon ES-1 Slide Copy attachment and several plain screw into the filter threads extension tubes to extend the position of the slide far enough in front of the lens for it to focus at 1:1. Surprisingly I placed these extension tubes between the 60mm macro and the E-P5 and pointed my contraption to an outside window to get daylight illumination and BAM, I get instant Auto-focus locked on! If I move the device to an area with less light it does rack out to infinity then back to acquire focus. I'm just blown away by how well my E-P5 seems to love my 60mm macro! One very happy camper!
