I've taken delivery of this what I think could be a useful accessory. Sadly, even though the blurb claims that it will fit all cameras with the 4/3 micro mount, the diameter of the rear-most component is too large and interfers with what looks like - but isn't - the reflex prism housing of the M-1 body. It will of course fit with an extension tube as an intermediary, but that surely was not the idea. Another issue I have with its design, is the orientation of the tilt: It's not in the horizontal axis, but at an angle, some 40 degrees off. A photo from one supplier illustrating the effect of the tilt seems to confirm this - unless he changed the framing intentionally. Very odd.
