A French site, Lepidi-photo, has published a new review on the Olympus 17mm f/1.8 lens. This is only a part 1 of 2(?) series which will be puhlished soon. The reviewer compares the Olympus 17mm against Olympus 12mm f2.0 which is a great lens. The manual focus ring moves just like the Olympus 12mm f2.0 lens, and it is just as pleasant to use it. The Olympus 17mm f1.8 is also more compact. Check this (and future parts of the review) out.
