Rollei Distagon EL 50 mm f/4 obiettivo HFT con scatola originale in condizioni perfette, pari al nuovo. Designed by Carl Zeiss and manufactured under license by Rollei in Germany, the Distagon 50mm f/4 HFT represents a technical benchmark in retrofocus wide-angle optics for the 6x6 Rolleiflex 6000 SLR system. Equipped with Rollei’s proprietary High Fidelity Transfer (HFT) anti-reflective multi-coating, this lens delivers high optical contrast, color rendering, and flare suppression under challenging lighting conditions. Operating as a standard wide-angle focal length (equivalent to approximately 28mm on 35mm film), it remains an essential wide-angle tool for architectural, landscape, and fine-art medium-format photographers.
