Olympus America V315030SU000 40-150 mm M.Zuiko Digital Telephoto Zoom Lens F4-5.6, Silver

Pros: This lens takes amazingly good pictures for being almost the cheapest thing available for MFT. It's very sharp, low vignetting, AF, and a usefully long focal length. Cons: Has some aberration fringing in high contrast situations, feels so cheap it might be made of recycled soda bottles. Other thoughts: Attached photos were all shot with an Olympus E-PL2 with IS on and hand held. Lens was at maximum aperture. While it has a couple dings against it, this lens is probably the best value you can get for your money on MFT. It takes images that are nice and sharp (though not quite as tack-sharp as some of Olympus' primes) across the image, corner to corner. It is also very light weight/compact for a 300mm equivalent zoom. It perfectly complements the kit lens (14-42) to extend your range significantly, or add it to your kit for when your fast primes don't have the reach you want. Whatever, it's a good little lens and you won't regret buying it (purchased on sale for $125).
