Thom's Mini Review: A surprisingly good lens, and probably a better choice than the Panasonic 8mm if you can deal with the lack of autofocus and don't mind setting exposure settings old-school style (aperture ring on the lens). Reasonably sharp into the corners, with little chromatic aberration to worry about. Likewise, handles flare better than the Panasonic. A bargain for the manual crowd.
