A bright, normal-length lens, the Leica DG Summilux 25mm f/1.4 II ASPH. from Panasonic is a 50mm equivalent prime for Micro Four Thirds mirrorless cameras. Characterized by its fast f/1.4 maximum aperture, this lens affords notable control over depth of field and is also well-suited to working in low-light conditions. Its optical design incorporates one UHR element and a pair of aspherical elements to reduce spherical aberrations and distortion, and a Nano Surface Coating has also been applied to suppress lens flare and ghosting for greater contrast in harsh lighting. A stepping autofocus motor, along with an internal focus design, contributes to quick and quiet focusing performance for both photo and video applications. Additionally, this lens sports a dust- and splash-resistant construction to benefit working in inclement conditions.

Normal-length prime is designed for Micro Four Thirds mirrorless cameras and provides a 50mm equivalent focal length.

Bright f/1.4 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.

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 AF motor, along with an internal focusing design, provides quick, smooth, and near-silent focusing performance to benefit both stills and video use.

Version II of this lens features a dust- and splash-resistant design to suit its use in trying weather conditions.

Rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with shallow depth of field techniques.
