Lens Overview — Opteka 650-1300mm T Mount

The Opteka 650-1300mm Telephoto Zoom Lens is a super telephoto zoom designed for DSLR cameras, covering a focal length range from 650mm to 1300mm. It uses a T-Mount interface, which makes it adaptable to a wide variety of camera bodies through the use of appropriate T-mount adapters. The lens is built for full frame coverage, so it can be used across both full frame and crop sensor DSLR systems.

With a maximum aperture of f/8, this lens is aimed at daytime or well-lit shooting conditions where extreme reach is the priority. Focusing is entirely manual, with no autofocus capability. There is no image stabilization, so shooting at these focal lengths will require a sturdy tripod or monopods to manage camera shake effectively.

The lens accepts 95mm front filters and weighs 2000g, which is a substantial but expected heft for a lens covering this focal range. Overall, the Opteka 650-1300mm is a budget-accessible option for photographers who want extreme telephoto reach in a manual, T-mount format for wildlife, astronomy, or distant subject photography.
