Contax 90mm f/2.8 Zeiss Sonnar T* Lens for G-Series, Titanium Review

The Contax 90mm f/2.8 Zeiss Sonnar T* is a compact portrait lens designed for the Contax G-series rangefinder cameras, a system that ceased production in the mid-2000s. Built with Carl Zeiss optics and the legendary Sonnar formula, it offers classic rendering and solid build quality in a lightweight titanium body. The 90mm focal length translates to a short telephoto ideal for portraits, and the T* coating helps control flare and maintain contrast.

Because the Contax G system is discontinued, this lens is exclusively available on the used market. At 117 dollars, it represents an affordable entry into high-quality Zeiss glass for those who already own a G1 or G2 body or who plan to adapt it to modern mirrorless cameras via third-party adapters. Adapting to mirrorless requires manual focus, as the G-mount autofocus is electronic and not mechanically coupled. The 46mm filter size is convenient and inexpensive.
