The reviews for the Olympus 60mm f/2.8 Macro are beginning to trickle out. And the lens looks awesome. They're comparing it to the 50mm f/2.0 for Four Thirds, which is a great lens. The new 60mm is said to be even sharper. And it makes a pretty good portrait lens too. (Unless you like blurry ears, then maybe you should get something with narrower depth of field, hehe.) As a portrait lens, they're even comparing it to the Olympus 75mm f/1.5, another stellar lens.
I guess the only downside of this lens is that at maximum aperture of f/2.8 it isn't as fast as other micro four thirds lenses. It's decent, not spectacular. It's not that big of a deal for macro photography, where narrow depth of field is VERY narrow and where you'll probably be looking for a way to light up your subject anyway with a flash, macro ring light or something. But you do get spoiled with fast primes on micro four thirds.
What that means to me are only those who are interested in macro photography need apply. Because if you want a portrait lens, the Olympus 75mm is better. But only because the 75mm is bloody amazing and poke-your-eye sharp. This lens is now number one on my lust list. And it's $499 which is reasonable.
For a great review, check out Robin Wong's site. The review is in two parts, macro and portrait performance. A good read!
