Have the 35s F3.5 Macro now 2 weeks and use it to my E-450 and E-520th Am just again thrilled by Olympus, the lens is quite small, very light and has a metal bayonet with a great price / performance ratio. There succeed beautiful macro shooting up to approximately 1-2 cm distance with a great image quality and sharpness. In low light and maximum aperture has a very shallow depth of field and you have already set the focus very precisely. But this (the shallow depth of field) makes so the attraction of macro photography. One can formally choose the pollen carrier or the stamp in bloom, it is desired to have sharp. The rest is blurred then evenly Farbenrausch, emerge from the then the tips of the petals again. The minimum focusing distance for normal photos (no macros) is 14 cm. In particular with the E-450 results in a very lightweight and handy combination with fixed focal length that you want to put it down garnichtmehr. Again a big recommendation from me. Addendum dated May 2012: Property me in early 2011 the Zuiko 2.0 / 50 Macro brought to and have to say that the 35s macro for me is equivalent in terms of image quality. Both are sharp even at maximum aperture, slightly dimmed absolutely great. Certainly the optical parameters (light intensity, focal length) are different. Advantage of 35er: 1: 1 magnification, much smaller and lighter than the 50s, with 35 mm also good for a normal lens Hiking / Biking usable, faster autofocus. Benefits at 50: sealed (against dust and humidity), higher light intensity and thus lower depth, distance to the subject is greater (especially in insects well.). For the price, the 3.5 / 35 mm is in any case absolutely outrageous and without competition. AZ
