Panasonic H-X2550 Leica DG 25-50mm f/1.7 lens is made for Micro-four third cameras. The development of this lens was announced back in May along with Lumix DC-GH6 and DC-GH5 II camera announcements. H-X2550 offers a 25-50mm zoom with a constant F1.7 aperture through at the zoom range. In full-frame terms, it has an equivalent focal length of 50mm-100mm.
This lens has a Dust, Splash, and Freeze-resistant design, so you don’t have to worry when using it outdoors in challenging conditions. The closest focusing distance it supports is 0.28m on the wide end and 0.31m at the tele-end. It offers a maximum magnification of 0.42x at the tele-end.
Panasonic is using a step-less aperture setup and along with the micro-step drive aperture system, it ensures optimal and consistent lighting when zooming or panning. It boasts exceptional barycentric stability to minimize image shifts during zooming.

From the manufacturer
LEICA DG VARIO-SUMMILUX 20-50mm / F1.7 ASPH. H-X2550 lens is built for mirrorless Micro Four Thirds (MFT) mount cameras, enabling F1.7 aperture brightness throughout the entire 50-100mm (35mm camera equivalent) zoom range. Its exceptionally high optical performance is suitable for both professional photographers and videographers. Comprising 17 elements in 12 groups, the lens system features three aspherical lenses and four ED (Extra-low Dispersion) lenses that effectively suppress the axial chromatic aberration and chromatic aberration of magnification. 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 lightweight. Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision autofocusing. 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.
