A fast, normal prime designed for Micro Four Thirds mirrorless cameras, the Lumix G 25mm f/1.7 ASPH., 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.

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 and a pair of aspherical elements help to achieve even illumination and sharpness for consistent performance throughout the aperture range.

The optical construction also helps to realize a compact overall form factor, measuring just 2″-long and weighing 4.4 oz.

A Nano Surface Coating has been applied to individual elements to noticeably reduce lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.

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.
