This is the second macro lens for Olympus's Four Thirds digital system, and while it lacks the 1:1 magnifying power of the earlier 35mm f/3.5 macro Zuiko, at f/2.0, it's much faster. Given the 2X 35mm lens factor on all Olympus DSLRs, the 50mm macro has a 100mm equivalent field of view -- more traditional in macro.
HANDS ON: Unusually light and compact for an f/2 macro lens, it appears rugged, with a stippled, matte-black surface. Its broad focusing ring is encircled by a furrowed, rubbery material for excellent finger purchase. Subject distance scales (feet in orange, meters in white), behind a plastic window, are large and easily legible. The extremely well-damped manual-focusing action has a pleasing drag; AF action is rapid and sure, though by no means silent.
