Panasonic LUMIX G 25mm F1.7 ASPH Micro-Four-Thirds mount lens review: Attractive option

Announced at the IFA 2015 in Berlin, this new Micro-Four-Thirds Panasonic LUMIX G 25mm F1.7 ASPH lens is a welcome addition to Panasonic’s existing range. Read on to find out how well this new model performs.

Specifications and Features

The Panasonic LUMIX G 25mm F1.7 ASPH is a fast, compact, and lightweight prime lens. It has a bright f/1.7 maximum aperture that allows for shooting low-light scenes and offers additional depth-of-field control over slower kit zooms.

Lens construction consists ofeight elements in seven groups, including two aspherical lenses to reduce chromatic and spherical aberrations for increased sharpness and clarity. The company says the optical formula also includes one ultra-high refraction (UHR) element that helps produce even illumination and sharpness for consistent performance throughout the aperture range. It achieves an attractive and smooth out-of-focus effect when working with shallow depth of field due to the rounded seven-blade diaphragm. If you shoot videos, you’ll find that the stepping motor delivers fast, smooth, and near-silent autofocus operation.

The new Panasonic LUMIX G 25 mm F1.7 ASPH focuses to 9.84’ (25cm) and measures 2.39” x 2.05” (60.8 x 52 mm). It weighs 4.41 oz (125g) and is available now for $300.00 (USD).
