Ok, so I'm looking at a 70-300 zoom lens for my Olympus evolt. Pricing is not bad at $300- $500. But I stumbled on to this Pro-Optic 500mm f/6.3 Mirror Lens for Olympus 4:3 System, SLR Cameras. Is this a lens ...or does it work with another lens What is this thing?
The 500 not only has a fixed focal length; it has a fixed aperture. You'll have to adjust ISO or shutter speed to adjust exposure. Its DOF isn't very good and the out-of-focus areas will appear as doughnuts.
