The R-System.
Precision without compromise.

History

More than 45 Leica lenses carry the invisible mark of one man's design philosophy — including 15 R-mount designs still treasured today. A biography of Walter Mandler, a complete list of his R-mount lenses, and what it means that his name now appears on new Chinese-made optics.

Technique

From Kodak Portra to Fujifilm Acros II and the new Harman Phoenix 200 — a practical guide to what's worth loading into your R-mount camera, with input from photographers who shoot Leica R cameras specifically.

Cinematography

From Shane Hurlbut ASC's Need for Speed to Cannes competition entries, Leica R-mount lenses have found a remarkable second life in professional cinema. What is the "Leica glow," and why are DPs choosing discontinued still lenses over purpose-built cinema glass?

Lens Guide

Leica lenses are among the most praised — and most scrutinised — optics in photography. What do independent testers, optical engineers, and working photographers actually find? And how does R-mount glass compare to the more famous M-mount lenses?

Culture

Film wholesale orders are up 127% since 2020, 312 new labs opened in 2025, and the people driving the boom have never shot film before. Here is why the R-mount system is one of the best-positioned legacy systems in that landscape.

Lens Review

Every serious camera system has one lens that defines it. In the R-mount system, that lens is the Summicron-R 50mm f/2. A thorough guide to its two versions, optical character, and why it remains the place to start.

Technique

Light seals, viewfinder cleaning, battery maintenance, correct storage — what you can do yourself, what to leave to a technician, and how to keep a camera that will outlast you.

Technique

From loading to rewinding — metering, film choice, the Sunny 16 rule, and developing a working method that suits the R6.2's deliberate, mechanical character.

Adapting

Adapters, camera settings, manual focus technique, IBIS, and which R-mount lenses perform best on Sony's full-frame mirrorless cameras — everything you need to get started.

Buying Guide

Every R-mount body rated — known faults, what to inspect before you buy, current pricing, and a first-purchase recommendation for different types of photographer.

Technique

What the cam count on an R-mount lens actually means, which bodies need which cams, how to use any lens on any body, and why cam count is irrelevant when adapting to mirrorless.

Lens Review

A guide to the Summilux-R 80mm, APO-Summicron-R 90mm, standard Summicron-R 90mm, and Elmarit-R 90mm — what distinguishes each, and which to buy first.

History

The story of the DIGITAL-MODUL-R — the optional 10-megapixel back that made the R8 and R9 the only 35mm SLRs in history to accept a user-installable digital back. What it was, how it worked, and why it matters.

Collecting

Beyond the standard black and chrome bodies, Leica produced a small but fascinating run of special editions across the R-mount line — from the olive-green R3 Safari to gold-plated commemorative R6.2 sets.

Buying Guide

In an era obsessed with digital connectivity, the Leica R6.2 offers something increasingly rare: complete independence from electronics. Here's why photographers are paying a premium for it.

Lens Review

Introduced in 1987, this apochromatic macro lens was ahead of its time. Tested on both film and adapted to modern mirrorless, its resolution figures still challenge contemporary optics.

History

Leica's SLR journey began hesitantly in 1964 and ended definitively in 2009. We trace the complete family tree: every body, every significant change, and what each generation got right.

Adapting

With flange distances in their favour, R-mount lenses adapt beautifully to Sony E, Leica SL, Nikon Z, and L-mount systems. We compare the best adapters and what to expect on each system.

Technique

Early R lenses carry only one metering cam, making them incompatible with open-aperture metering on later bodies. We explain the difference and the workflow for getting correct exposures.

Comparison

The M-mount is Leica's most celebrated system — but how does it compare to the R-mount in practice? We examine the key differences in facts and in use, and make the case for the R as a serious and affordable alternative.
