Olympus 50-200 mm f/2.8-3.5 zoom for 4/3 cameras. This is part of their High Grade Series of lenses. Equivalent focal length (35mm) is 100-400. The glass is pristine. Because it is for 4/3 cameras, you will need a DMW-MA1 adapter (not included) to use it on a micro 4/3 camera (which is what I did). This lens costs $1199.00 at B&H. Comes with lens caps and a removable tripod mount.
$350 includes shipping within CONUS.
