LEICA HEKTOR T2.1 50mm L-Mount

Leitz Hektor T2.1 50 mm L-Mount: the essential standard focal length

The Leitz Hektor T2.1 50 mm L-Mount serves as the core of the HEKTOR series. Covering full-frame sensors, it provides a natural perspective well suited for dialogue scenes, character-driven storytelling, and versatile handheld shooting.

It combines crisp center resolution, gentle roll-off toward the edges, expressive flares, and a smooth, cinematic bokeh. The constant T2.1 aperture ensures consistent performance in both bright and low-light conditions.

A design rooted in Leica’s optical heritage

Inspired by Leica optical formulas from the 1930s, 1950s, and 1970s as well as classical Petzval-inspired characteristics, the 50 mm offers:

• natural, gentle contrast

• circular bokeh thanks to the 9-blade iris

• smooth fall-off

• subtle peripheral softness

• expressive but controlled flares

Modern coatings improve reliability, reducing glare and chromatic aberration.
