A small, unobtrusive and sharp lens. A real bargain at the price. I know of no other system (at the time of this post) that offers such excellent lenses for their cameras. M43 is the way to go is you want a good selection of lenses at reasonable prices. No other manufacturer offers that. Of course I'm talking generally about the m43 system here we have to incluse Olympus and Panasonic, although the Panasonic lenses tend to be dearer and the Olympus cameras tend to be dearer than the Panasonic counterparts. Whichever way you decide to go, you just....can't...lose.
