PANASONIC 10-25MM F1.7 H-X1025E

Panasonic Leica DG Vario-Summilux 10-25mm f / 1.7 ASPH. Lens

A unique lens with a clearly bright design, the Leica DG Vario-Summilux 10-25mm f / 1.7 ASPH. Panasonices a zoom equivalent to 20-50 mm for cameras without Micro Four Thirds mirror. The impressive constant maximum aperture f / 1.7 allows improved control of depth of field and low-light shooting capabilities throughout the zoom range. Balancing the impressive performance of f / 1.7, the optical design incorporates a series of elements of low dispersion, aspherical and high refractive index, which help greatly reduce chromatic and spherical aberrations to improve clarity and sharpness. Complementing the optics, this lens is also characterized by its durable and weatherproof physical design, along with a fast autofocus system, versatile focus clutch design and a continuous, non-click opening ring to suit the applications of video.
Wide-to-normal zoom is designed for Micro Four Thirds mirrorless cameras and offers an equivalent focal length range of 20-50mm.
Impressively bright f / 1.7 constant maximum aperture excels in low light conditions throughout the zoom range and also offers improved depth of field control.
Three aspherical elements, four extra-low dispersion elements and an ultra-high refractive index element combine to suppress color stripes, chromatic aberrations and spherical aberrations for high clarity, sharpness and color accuracy.
The fast 240fps autofocus unit, along with an internal focus system, offers smooth, precise and quiet focus performance to benefit both still and video applications. In addition, a focus clutch mechanism offers particularly fast AF / MF switching.
The physical opening ring has a continuous click-free design for a smooth and quiet opening change for the benefit of video applications.
Splash, dust and freeze-proof design works in adverse weather conditions.
The rounded nine-leaf diaphragm contributes to a smooth and pleasant bokeh quality.
