90–230mm · f/4.5
Overview
The Vivitar 90-230 mm f/4.5 Auto Tele T4-TX mount lens, manufactured by Tokina, exists in multiple versions: an early T4 fixed mount, a first-generation TX with 12 elements in 9 groups, and a later compact close-focus TX with 13 elements in 9 groups (Boomer Depp). Optical strengths are not detailed in the excerpts, but the lens is noted for its close-focus capability in later versions. Build and handling vary by generation, with the earlier TX featuring a tripod mount. It suits users seeking a vintage telephoto zoom with adaptable T4/TX mounts, though specific optical performance is not addressed.
