Great Japanese-made zoom lens in excellent condition with clean glass and no fungus. This lens sells around the Internet for $300-350. It's designed for a 1" format, so there's no vignetting/distortion at the edges of a mu-4/3 camera. You can use it with or without the C-mount flange, but I'm not sure what kinds of adapters are required in each case (flange is included, but m43 adapter isn't). It was a bit of an impulse buy for me because it's such a great deal, but I actually already have an old lens that covers this range, and the old lens wins the battle because of sentimental value (my dad bought it in 1984, and I essentially grew up with that lens on his Minolta X-700). There's a spec sheet here: http://www.rmaelectronics.com/specsheets/L7Z2835-L5Z6004_Specs.pdf $75 + shipping.
