Panasonic H-H025E-K

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.
