All around F1.7 quality
This lens is great for everything from snapshots indoors in low light to portraits with a distinctive bokeh effect in the background. Enjoy the quality of F1.7 throughout the 50-100mm zoom range (35mm camera equivalent) along with ease-of-use delivered by a compact, lightweight design. Seamless iris control allows users to shoot video with exceptionally smooth changes in exposure when zooming or panning, and when used with a compatible camera, the rotation angle of the focus ring can be adjusted manually.
Superb close-up performance
This lens features superb close-up performance and is designed to expand the range of creativity, featuring a closest focusing distance of 0.31m (at the telephoto end)* and 0.42x maximum magnification (35mm camera equivalent at the telephoto end).
*Closest focusing distance of 0.28m (at the wide end), 0.31m (at the telephoto end).
Dust, splash and freeze-resistant design
LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. is designed to keep shooting in the toughest conditions thanks to its dust- and splash-resistant construction and even in temperatures as low as -10 °C.
*Dust and Splash Resistant does not guarantee that damage will not occur if this lens is subjected to direct contact with dust and water.
Ideal for video recording
The lens offers fast, accurate autofocus and smooth aperture changes, critical for the modern content creator, allowing you to record beautiful 4K video and stills without disturbing your subject. Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision auto focusing. In addition to the silent operation achieved by the inner focus drive system, the stepless aperture ring and micro-step drive system in the aperture control section help the camera to smoothly catch up to brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. A focus ring is equipped for intuitive, precise focusing and linear/ non-linear setting can also be switched with this ring.
