The Samyang 650-1300mm f8-11 is a super-telephoto manual focus zoom lens for Full Frame or APS-C size sensor cameras, with a universal T-Mount. At 1300mm it gives a massive 26x magnification compared to a standard 50mm lens, great for long range shots or where a very compressed perspective is required. It includes a rotatable tripod collar, as use with a sturdy tripod is essential. The T-mount must be purchased separately and simply screws on the rear of the lens, so if you change camera it’s easy to convert the lens for a modest price.
