Had the lens approximately 0.5 years use, super sharpness and contrast. It is sometimes a bit slow when focusing, which did not bother me during macro shooting, I always sharp point manually. The second application were portraits, which I like to do in natural light. Here the lens has reached its limits due to the only average brightness. For the price however, it is an unbeatable access to the Macro photography. I have submitted the lens and bought the 50mm / 2.0 Olympus. This is of course superior in luminous efficiency, for portraits but are clearly the better focal length 35mm.
