This is a compact lens with a traditional focal length for street photography, making it attractive for the E-M10 or PEN-F. I think it looks good. The downside to his focus is that he's slow, noisy, and hunts too much. Motor lag is noticeable in manual focus modes - the only Olympus MFT lens I've used where this is true. Since I wouldn't recommend it for street photography, that leaves only landscape and the like where its only advantage is price.
