Description

With over fifteen years of evolution in the perfection of its design, Opteka’s 500mm f/8 preset lens continues to be an indispensable tool for any photographer's arsenal. Opteka stands tall as an American leader of cutting-edge professional camera equipment. Based in the USA, our knowledgeable staff is always ready to take your questions. In a market flooded with generic imitations, trust a brand that has paved the way for quality and innovation for decades. The Opteka 500mm f/8 manual focus preset 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. A Opteka 2x doubler (not included) converts this 500mm lens into 1000mm. When combined with the included T-mount to fit your Samsung NX camera system, this super telephoto works on both "full frame" as well as "APS-C" style mirrorless 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.
