I just got the new Sigma 30mm f2.8 lens today and did some quick tests with my E-P2 body. First here are some photos of the lens. Here is what the lens looks like, a unusually small front element and a large rear lens element. Found a nice standard 46mm metal lens hood on ebay for it for around $5 (unlike the Sigma 19mm it does not come with a lens hood) and added a 58mm pinch lens cap. On my E-P2 body Size compared to the Olympus 45mm f1.8 A very lightweight and affordable kit, from left to right: Panasonic 14mm f2.5, Olympus 45mm f1.8, Sigma 30mm f2.8 and manual focus Olympus OM 100mm f2.8 MC Here are some tests outdoors at different distances. E-P2, ISO 200, processed with Adobe Camera RAW with default sharpening, 100% crops. I'm quite impressed, very usable wide open at f2.8, hitting its sweet spot at f5.6 with excellent edge performance. Test 1 Test 2 Test 3 Bokeh test, shot wide open at f2.8. Pretty decent, no distracting elements or funny patterns, but not a bokeh monster either. Finally I photographed a part of my reef tank, handheld at f4.0. I focused on the tenticles of the Elegance Coral (the large green one) and they were tack sharp at 100%. Autofocus I've been asked to comment on the autofocus. Its virtually silent. Even with no other noise in the room when I focus with the lens I really can't hear it doing so. The construction of the lens is internal focusing so its motor does not have to move an entire focusing helecoid, only one or two lens elements within the body - hence the silence. A bonus of this construction is that there are also less cavities for dust to make their way into the lens. In terms of focus speed from its closest to infinity it seems to be pretty decent, but then the E-P2 being an older body may not be the best one to judge focusing speed. The focus collar is nice an wide and its a focus-by-wire design like the Olympus 45mm. The collar does not seem to be as smooth as on my Olympus 45mm, but it does seem to be getting smoother with use. I have no issues with manually focusing using focus-by-wire. Here is an image (shot wide open at f2.8) showing the lens focused at its closest focusing distance, you can judge the resulting magnification. On a aside I notice spectral highlights in the bokeh are rendered as nice and round - see the round blob above my hand. Aperture blades on the lens are nice and rounded when the lens stops down rather than hex shaped. Conclusions Excellent performance and a great price of only $199. The Panasonic 20mm f1.7 is a excellent lens but in terms of angle of view I find it too close to the 14mm for my tastes. If you shoot a lot in the 20mm to 30mm focal range, than get the Panasonic/Leica 25mm f1.4 for mission critical and low-light work instead. Alternatively if it's not your most used focal length and you need a good inexpensive small lens for the times that you do need something in this range in your camera bag, then I think the Sigma 30mm f2.8 makes an excellent buy.
