Key features:

• F1.7 aperture throughout the focal range
• Versatile zoom lens
• Silent operation for video
• Fast and precise focus
• Sharp images with minimal distortion or aberration
• Dust and weather resistant*

The lens features a constant F1.7 high-speed aperture at all focal lengths which produces beautiful bokeh.

Comprising 16 elements in 11 groups, the lens system features an aspherical lens and three ED (Extra-low Dispersion) lenses to minimise chromatic aberration. Spherical aberration and distortion are also corrected by the aspherical lenses for stunningly high resolution. The use of aspherical lenses and the optimum design of the lens system results in a compact size and light weight despite its outstanding optical performance.

The Panasonic Lumix G Leica DS Vario-Summilux 25-50mm F1.7 ASPH lens excels in video recording performance with a mechanism that suppresses focus breathing at the entire zoom range. 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 minimise image shifts during zooming while the focus ring is equipped with a manual focus clutch and ensures intuitive and precise focusing. The lens boasts a minimum focusing distance of 0.28m (at wide end, 0.31m at tele end) and the maximum magnification ratio of 0.42x (35mm camera equivalent) for superior macro photography. The lens can also be switched between linear and non-linear focus settings.

The rugged dust/splash-resistant* design to withstand use under harsh conditions even at minus ten degrees Celsius for high durability.
