Description — Tokina 100-300mm f/4 SD
The Tokina 100-300mm f/4 AT-X SD is a full-frame telephoto zoom lens built for DSLR systems, offered in Canon EF and Nikon F mounts. Its focal length range spans 100mm to 300mm, with a consistent f/4 maximum aperture held throughout the entire zoom — a feature that keeps exposure settings predictable as you adjust your composition. The lens weighs 1,500g, reflecting the robust build expected of a telephoto zoom in this range.
A 77mm filter thread provides compatibility with a wide range of photographic filters. Both autofocus and manual focus are supported, giving users the flexibility to work across a variety of shooting scenarios. It is worth noting that no image stabilization is included, so steady technique or physical support becomes more important, especially toward the longer end of the focal range.
As a full-frame design, it delivers complete coverage for full-frame DSLR bodies while remaining functional on crop-sensor bodies within the same mount family.
