Opteka 500mm/1000mm f/8 Manual Telephoto Lens for Olympus OM-D E-M1, E-M5, E-M10, PEN-F, E-PL8, E-PL7, E-P5, E-PL5, E-PM2, E-P1, P2, PL1, PL1s and PL2 Micro Four Thirds Digital Cameras

The Opteka 500mm / 1000mm f/8 manual focus preset lens is a lightweight, compact lens, designed to make it the perfect long-range lens for sports, wildlife, and other telephoto photography applications. The Opteka 500mm / 1000mm lens is a classic refractor-style T-mount lens, with an aperture diaphragm in the middle of the lens body to stop down the aperture when necessary. However, it is assumed that much of the shooting with such a lens will be at its maximum f/8.0 aperture, with a tripod, monopod, or other such support. The included 2x doubler converts this 500mm lens into a 1000mm. When combined with the included T-mount to fit your camera system, this super telephoto works on both "full frame" cameras as well as the "APS-C" style digital cameras. You can use the lens in "M" manual exposure mode or "A" aperture-priority mode only. This lens' sophisticated achromatic refractor design yields images with pleasing peak contrast and well-controlled flare. It can be used at maximum aperture on a very bright day for some images of moving subjects.
