The Leica Noctilux-M 75mm F1.25 ASPH is a fast, high-quality and decidedly heavyweight short telephoto prime lens, designed for use with Leica's digital M-series rangefinders. A companion to the company's existing 50mm Noctilux-M 50mm 0.95, the new 75mm is better suited to classic portraiture. Its nine-element, six-group construction is comprised exclusively of high anomalous partial dispersion and low chromatic dispersion glass, and contains two aspherical elements.

The incredibly shallow depth of field at F1.25 (not to mention its sheer size) make it tough to shoot with a conventional optical rangefinder

As you might expect, as well as being very pricey the 75mm F1.25 is also quite a handful, with a 67mm filter thread and weighing in at a total weight of 1055g (2.3 lb). While natively an M-mount lens, the incredibly shallow depth of field at F1.25 (not to mention its sheer size) make the 75mm Noct very tough to shoot with a conventional optical rangefinder. As such, we've mostly been shooting it on an M10 coupled with Leica's Visoflex electronic viewfinder, and on an SL via an adapter.

We've been grappling with the 75mm F1.25 for a little while, and we're working on a short shooting experience article. In the meantime, take a look at our sample images and let us know what you think.
