Carl Zeiss Sonnar 90mm f2.8

The Carl Zeiss Sonnar T* 90mm f/2.8 is a classic short telephoto prime originally built for the Contax G rangefinder system. Based on the historic Sonnar optical formula, it's prized for its compact size, smooth rendering, and the kind of contrast and color signature Zeiss glass from this era is known for, with Zeiss's T* multi-coating helping control flare and ghosting.

At f/2.8, it's a natural choice for portraits and general telephoto work where a discreet, lightweight lens matters more than autofocus speed or modern electronics. Since it was designed for the G-mount rangefinder system, it typically requires an adapter to be used on other camera bodies.
