The classic wide-angle lens for medium-format photography
Many photographers consider the Distagon® T* 4/50 FLE CFi lens the ideal all-purpose wide angle lens in medium format. The modern optical design guarantees high performance, even close-up, thanks to "floating elements". Corner-to-corner illumination is very even with all aperture settings common in advertising, nature and landscape photography, and veiling glare is extremely well controlled. So the Distagon T* 4/50 FLE CFi lens is well suited for landscape shots with large blue sky areas.
Distortion is kept remarkably low, qualifying the Distagon T* 4/50 FLE CFi lens for both professional architecture and product photography – a unique strength of retrofocus wide angle lenses from Carl Zeiss. On top of all these benefits the Distagon T* 4/50 FLE CFi lens is remarkably compact.
