Olympus ZUIKO DIGITAL ED 50mm 1:2.0 Macro Lens Review

Good Points
Superb image sharpness and clarity right to the edges, and absense of geometric and chromatic aberrations. Being an f2 lens, it lets in lots of light. It's well sealed against dust and moisture.

Bad Points
I agree with another reviewer that if the camera fails to autofocus, it takes a relatively long time to go through a complete focus cycle. Also the autofocus motor is quite noisy and the lens is heavier than it looks. But those are very trivial issues.

General Comments
I bought it in the expectation of mainly using it for photographing flowers, insects and other relatively small subjects up close. However I've found that this is the lens which is on my E-520 camera most of the time. The incredibly sharp colour-accurate photos it takes make it worth taking a few dozen steps back from larger subjects, rather than putting on the 14-42mm zoom lens I got with the camera. I certainly recommend it.

[Note that this is a Four Thirds format digital lens, not a 35mm film lens as stated at the top of the review page near the picture of it.]
