ZEISS Distagon T* 21mm f/2.8 ZF.2 Lens for Nikon F
Ultra-Wide Precision Prime – Distagon Optical Design, Floating Elements, Carl Zeiss T* Coating & Electronic CPU Interface

The ZEISS Distagon T* 21mm f/2.8 ZF.2 is an ultra-wide manual focus prime lens engineered for full-frame FX-format and DX-format Nikon F-mount cameras. Renowned for its optical correction and dramatic perspective, this lens delivers exceptional corner-to-corner sharpness, high contrast, and minimal distortion, making it a premier optic for landscape, architecture, interior, and astrophotography.

Optically, the lens employs a Distagon retrofocus configuration featuring a floating elements system and anomalous partial dispersion glass elements. This design suppresses field curvature, chromatic aberrations, and optical distortion across the entire focusing range. Every lens surface is treated with iconic Carl Zeiss T* anti-reflective coatings to maximize light transmission, eliminate internal flare and ghosting, and deliver outstanding color fidelity even in challenging backlit environments.

Housed in an all-metal lens barrel with refined focus mechanics, the lens features physical depth-of-field and distance scales alongside a manual aperture control ring with 1/2 EV click-stops. As a ZF.2-series lens, it includes an integrated electronic CPU interface that enables full camera-controlled aperture setting, EXIF metadata transfer, auto-exposure metering, and in-camera focus confirmation LED indicators on compatible Nikon DSLRs.
