Unveiled: Panasonic LUMIX G Leica 15mm f/1.7 Lens

Share

Panasonic has announced a new prime lens for their Micro Four Thirds format cameras—and this is anything but just another new lens. The LUMIX G Leica DG Summilux 15mm f/1.7 ASPH lens brings with it the best of the Panasonic/Leica collaborative efforts.

For starters, the lens provides the 35mm format equivalent of a 30mm focal length lens, which is a nice option for wide-angle work without getting into heavily exaggerated perspectives. It nestles between the 14mm f/2.5 and the 20mm f/1.7 Lumix G prime lenses but offers a faster maximum aperture than the 14mm, as well as the renowned Leica optical and design qualities. Its compact, not pancake, form factor is complemented by a substantive all-metal design featuring an aperture control ring and an AF/MF switch on the barrel. Its filter thread measures 46mm in diameter.

A wide f/1.7 maximum aperture is effective in low-light situations and provides shallow depth-of-field control. Its minimum focus distance is 7.87". The lens features an inner focus system and its newly developed stepping motor enables fast, smooth, and silent autofocus for use in both photo and video recording. Three aspherical lens elements reduce aberrations and distortion, and Panasonic’s Nano Surface Lens Coating minimizes reflections, resulting in sharper images with less ghosting and flare. 

This lens is well suited for the recent Lumix G mirrorless cameras, not only due to its compact size and durability, but it is optimized for use with the high-speed continuous shooting rate of the G cameras as well as their contrast-detect Light Speed Autofocus systems.
