Bought this lens a few days ago and yesterday I got to make some shots to get acquainted with it and also to evaluate its optical qualities. I was positively surprised by its sharpness, compared to this lens my PC-Nikkor 35/2.8 of yesteryear was a piece of cr*p. Distortion is not too obvious, but visible in critical circumstances, especially when shifted. Boring test shots in full-size here. It's the single-coated version, which makes itself known by being fairly sensitive to flare and a touch less contrasty than I'm used to from other Olympus OM Zuiko lenses. In actual picture taking it's just great to be able to eliminate too much of a foreground by simply shifting up a few mm. I find that more important than being able to catch a tall building, which is the standard example of the use of a shift lens. Only in the first shot the lens is shifted to its maximum 12mm (I think).
