A 50mm-like Micro Four Thirds Prime Lens

Panasonic Lumix G 25mm f/1.7 Lens

A fast normal Panasonic Lumix G 25mm f/1.7 ASPH. Lens designed for Micro Four Thirds mirrorless cameras, is a 50mm (35mm equivalent lens) featuring a bright f/1.7 maximum aperture for upgraded low-light shooting and control of depth of field. A single UHR (Ultra-High Refractive Index) element is paired with two aspherical elements to diminish chromatic aberrations and distortions for consistent sharpness and illumination edge-to-edge. The optical construction also helps to create a overall compact form factor, measuring a scant 2"-long and weighing in at 4.4 oz. An advantage to both still images and video acquisition, this lens also makes use of a stepping motor for buttery smooth, quiet AF performance which is compatible with the Lumix camera high-speed contrast-detection focusing systems.

Engineered for Micro Four Thirds mirrorless cameras, this lens features a 50mm (35mm equivalent) focal length to provide a normal perspective. Fast f/1.7 maximum aperture is an advantage for shooting in trying lighting situations and also offers extensive control over focus for selective focus applications.

A single UHR element helps to manage even illumination and sharpness for consistent performance all through the aperture range.

Two aspherical elements diminish chromatic and spherical aberrations for enhanced sharpness and clarity.

Stepping motor provides fast, smooth, and nearly-silent AF performance as an advantage for both still image and movie recording.

Rounded seven-blade diaphragm delivers a smooth out-of-focus aspect when shooting with shallow depth of field techniques.
