Sometimes I need longer reach than what the RF coupled 200mm Komura can give me. This is with a Nikkor-H 300/4.5 on the Olympus EP2. From my deck. We have a big back yard. I should add: I use the Olympus EVF-2, which is identical to that available for the M type 240. I have to use the 10x magnification function for focus, still can miss a little.
