When I got the Olympus PEN E-P2 it came with the M. Zuiko Digital 17mm f2.8 lens. I already use the Zuiko Digital 25mm f2.8 lens on my E-510 so the only difference here for me is that its on a Micro 4/3rds camera and instead of having a focal length of 25mm, I have a focal length of 17mm. Other than that it is a very nice lens that I would recommend to anyone using a micro 4/3rds camera.
