Opteka 500mm (with 2x- 1000mm) f/8 Manual Telephoto Lens for Canon RF-Mount EOS R6, R5, R3, Ra, RP and R Mirrorless Cameras

The Opteka 500mm / 1000mm 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. The included 2x doubler converts this 500mm lens into 1000mm.

When combined with the included T-mount to fit your Canon RF camera system (included), 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.
