The Zeiss EF Otus 28mm f/1.4 Apo Prime Lens offers sharp image quality, powerful lighting contrast capabilities, and incredibly smooth internal focus mechanism. Considered the Master Primes of photo lenses, this lens has been modded for cine use. It features an apochromatic optical design to significantly reduce chromatic aberration and a floating elements system for consistent performance across the focusing range. And the Zeiss T* anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity. This lens delivers exceptional edge-to-edge sharpness!
