A fast, normal prime designed for Micro Four Thirds mirrorless cameras, the Lumix G 25mm f/1.7 ASPH. Lens from Panasonic is a 50mm equivalent lens featuring a bright f/1.7 maximum aperture for enhanced low-light shooting and depth of field control. One UHR (Ultra-High Refractive Index) element pairs with two aspherical elements to reduce chromatic aberrations and distortions for consistent edge-to-edge sharpness and illumination. The optical construction also helps to realize a compact overall form factor, measuring just 2"-long and weighing 4.4 oz. Benefitting both stills and video capture, this lens also incorporates a stepping motor for smooth, quiet autofocus performance that is compatible with Lumix cameras' high-speed contrast-detection focusing systems.
Designed for Micro Four Thirds mirrorless cameras, this lens provides a 50mm equivalent focal length to represent a normal perspective.
Fast f/1.7 maximum aperture benefits working in difficult lighting conditions and also enables extensive control over focus placement for selective focus applications.
One UHR element helps to achieve even illumination and sharpness for consistent performance throughout the aperture range.
A pair of aspherical elements reduces chromatic and spherical aberrations for increased sharpness and clarity.
Stepping motor delivers fast, smooth, and near-silent autofocus performance to benefit both still photograph and movie recording applications.
Rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with shallow depth of field techniques.
