Selling a 500mm lens for SLR cameras. I used it with the Olympus e510 but it can also be used with e520 and e420. All images are just over a month old and have been used to take less than a dozen pictures.
Included are: Opteka High Definition 500mm Telephoto Lens, T-Mount Adapter, ND-2X Filter, ND-4X Filter, Skylight Filter, Pouch, Front and Rear Lens Caps.
Following is the information from the company website:
The Opteka mirror lens is incredibly compact and lightweight. Using an advanced reflex design, this is a mirror lens that is ideally suited for wildlife and sports photography. It has a fixed aperture of f8. It comes complete with a soft pouch and three (3) rear mounted, 30.5mm filters, (ND-2X, ND-4X & Skylight).
Opteka mirror lenses incorporates advanced computer designed optics and the latest in multi-coating techniques. The process of multi-coating assures virtually flare free photographs even under adverse lighting conditions resulting in crisp high contrast pictures with full color fidelity.
Advances in high-index / low-dispersion optical glasses, new barrel materials, and exotic anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing, are combined to produce lenses of unprecedented quality. Diamond-cut from crystal-clear, water-white optical glass, Opteka lenses are ground and polished to a precise precision.
