Lens Overview — Tokina AF 300mm f/2.8 SD

The Tokina AF 300mm f/2.8 AT-X Pro SD is a full-frame, prime telephoto lens built for DSLR systems, available in both Canon EF and Nikon F mounts. At 300mm with a maximum aperture of f/2.8, this lens sits in a class typically favored by photographers who need a long reach combined with strong light-gathering capability. Being a prime lens, it offers a fixed focal length with no zoom range to manage, which generally translates to a simpler, more robust optical design.

The lens supports both autofocus and manual focus operation, giving shooters flexibility depending on the shooting scenario. At 2,400g, this is a substantial piece of glass that reflects the engineering requirements of a fast, long telephoto prime at this focal length. The 112mm filter thread is notably large, consistent with the front element size needed to achieve f/2.8 at 300mm.

There is no image stabilization built into this lens, so shooters will need to account for camera body stabilization or stable support systems such as a monopod or tripod when working at these focal lengths. The lens covers a full-frame image circle, making it compatible with both full-frame and APS-C DSLR bodies across its supported mounts.

Description — Tokina AF 300mm f/2.8 SD

The Tokina AF 300mm f/2.8 AT-X Pro SD is a prime telephoto lens designed for full-frame and APS-C DSLR cameras. With a fixed 300mm focal length and a maximum aperture of f/2.8, it delivers a fast, dedicated telephoto option for photographers who regularly shoot at this focal length. The lens is offered in Canon EF and Nikon F mounts, covering the two most widely used DSLR systems.

Focus options include both autofocus and manual focus, giving users control over their preferred focusing method. Weighing 2,400g, this is a heavy lens that reflects the physical demands of its optical design, and the 112mm filter thread means front-mounted filters will need to be sourced in a large diameter. Image stabilization is not included, so support equipment or in-body stabilization should be considered for handheld use.
