I use it as a substitute for the complicated lens with my Olympus OM-D 10M II camera. In general, I could not be happier with the results, as the photographs are exquisite. An excellent choice for use as a basic lens. I would suggest it! Pros: Outstanding optical performance at a very reasonable price. Excellent crispness over the entirety of the frame. Compact and quite light in weight. Excellent for general use in the great outdoors. When it comes to focusing, this lens is quite quick. When the lens is shook, a noise is heard that sounds as if something is hanging within (this is a design feature), which can be a bit annoying. Other disadvantages include. Case is easily marked and prone to scratches. The lens does not lend itself particularly well to video use.
