    Overview

    The Carl Zeiss Sonnar T* 90mm f/2.8 is a compact, lightweight telephoto prime (240g) originally for Contax G cameras, praised for excellent sharpness, contrast, and color rendition. It produces creamy bokeh and is flare-resistant. Weaknesses include no built-in focus ring; adapting to mirrorless requires either a mechanical adapter (which can be poor quality) or an electronic adapter like Techart for AF, but AF is slow and unreliable in low light. Build quality is solid. It suits photographers seeking a small, affordable ($130–200) manual-focus telephoto with superb optics, especially for portraits.
