The construction of the lens is basic as to be expected from an affordable, consumer-grade lens. The lens body is made entirely of plastic down to the lens mount which is also why the lens is extremely light-weight at just 190g.

It's designed to complement the entry-level M.Zuiko 14-42mm zoom that ships with Olympus PEN bodies like the E-PL5($199.00 at Amazon). It gives you the telephoto reach that the standard kit zoom can't manage, covering an 80-300mm field of view in terms of traditional 35mm photography. It doesn't have an ambitious aperture, and it's not as sharp from edge to edge as more expensive lenses, but it performs well in good light, bringing distant objects into clear view.

I find this lens great to get those shots where a little more zoom goes a long way.

Durable; Easily Interchangeable; Lightweight

If you spend money on digital SLR camera, you should purchase lens to go with it. It is major investment for the camera body, but the lens make the huge difference for the pictures. This lens is compact and durable. I like the lens a lot, the only complaint is the lens act slowly under low light.
