The Opteka 500mm / 1000mm f/8 Manual Focus 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. IR remote will only work if your camera supports an IR remote function. The Circuit City CCIR Remote Control is a wireless infrared shutter release capable of instantly triggering the shutter of select digital cameras, without disturbing the camera, up to a enhanced distance of up to 48' (varies by camera brand) in front of the camera. - Achromatic refractor 500mm f/8 lens in T-mount - Multicoated optics - Knurled focus ring to the front of the lens - Fixed tripod collar - Meant for use with monopods, chest supports, or tripods Includes Opteka 500mm Super Telephoto HD Preset Lens w/ 2x Doubler Opteka Lens Caps Opteka T-mount Opteka 67mm UV Filter Opteka 67mm UV Hood Opteka Lens Cap Keeper Circuit City Wireless IR Infrared Remote Circuit City Cleaning Kit - Lens Pen, Air Blower, Dust Brush, Empty Spray Bottle, 3x5" Lens Tissues (50), Standard Microfiber (2), Large Microfiber.
