Opteka 500mm f/8 Preset Telephoto Lens for T Mount

Designed for photographing distant subjects, the 500mm f/8 Preset Telephoto Lens from Opteka is a super telephoto prime featuring a threaded T mount for adapting to a wide variety of camera types. Its optical design is fully multi-coated to suppress lens flare, ghosting, and surface reflections for increased contrast and color neutrality when working in strong lighting conditions. Manual exposure control is possible via the direct aperture dial, and manual focus operation permits working with subjects as close as 33' away. A soft lens pouch is included with the lens to protect it during storage or travel.
