The Panasonic Lumix S1R is a full-frame mirrorless camera with 47 Megapixels, built-in stabilisation and 4k 60p video. it's one of two bodies launched by Panasonic as part of its new L-mount alliance with Leica and Sigma; the two new Lumix S bodies are differentiated by resolution with the S1...

Panasonic's officially launched its new full-frame mirrorless camera, the Lumix S1R. We got to spend some time with a pre-production sample of the S1R at its official launch in Barcelona.

Superb EVF - best on the market; Very effective image stabilisation; 187MP High Resolution mode is unique; Highly responsive in use

Somewhat large for a mirrorless camera; Power control in awkward position; Stiff menu pad control; V-Log set to be optional paid-for update

Panasonics' Lumix S1R is amazing, but few photographers will need its killer feature.

Excellent image quality; Robust design and build quality; Best available electronic viewfinder; Good subject detection autofocus; 187MP high resolution mode

Gargantuan; Intermittent autofocus errors; Not as valuable as standard S1

The Lumix S1 and S1R are Panasonic's latest digital cameras , and they're a bit of a departure from the cameras the company has made in the past. These new Lumix models are Panasonic's first full-frame mirrorless cameras - meaning, in layman's terms, that the cameras have larger image sensors...

An extremely capable full-frame mirrorless camera – if you're a pro who likes larger bodies, dual card slots and features like 6K Photo, then the S1R is a strong alternative to high-res rivals from Nikon and Sony. Its lens collection is far from fully developed, though, and anyone looking for a small and light mirrorless camera should look elsewhere.

High resolution sensor produces great results; Superb electronic viewfinder; Handy unique features like 6K photo; Tr-axial tilting touchscreen;

Larger and heavier than rivals; Not great for action; Limited battery life; Lens options quite limited (for now);

: The Panasonic Lumix S1R is at least as good as its competitors – but there's plenty of competition

Superb image quality; Pro level controls and build; SD and XQD memory card slots

One of the larger mirrorless cameras on the market; Weak battery life; More expensive than similar cameras

The S1R is particularly suitable for portrait and landscape photographers as well as pro photographers who shoot weddings, fashion and commercial products, particularly where high-resolution images are needed for making poster-sized enlargements.

And the cost is a concern. The $3,700 asking price is more than the Nikon ($3,400) or Sony ($3,200) alternatives. A paucity of affordable lenses compounds matters, though that's sure to be addressed as Sigma has announced plans to release some lower-cost lenses in L-mount.

Excellent 47MP full-frame sensor; 5-axis sensor stabilization; Big, sharp EVF; Good control system; Backlit control buttons; Protected from dust and splashes; Top information LCD; 4K video at up to 60fps

More expensive than competitors; Obnoxiously heavy; Contrast focus limits tracking speed and burst rate; Limited lens selection

Panasonic's first full-frame cameras are here. The company, long tied closely to the Micro Four Thirds format, has partnered with Sigma and Leica to build cameras around Leica's L-mount, starting with the Lumix DC-S1R ($3,699.99, body only), a 47MP high-resolution model, and its 24MP twin sibling, the S1 ($2,499.99). The S1R delivers superb image quality and excellent, stabilized 4K video, but you pay a premium for the camera, and it's significantly heavier than competing models. As such, we still recommend the Sony a7R III as our Editors' Choice for photographers looking for a high-resolution mirrorless camera. Mirrorless, But Not Lightweight The lines between SLRs and mirrorless cameras have blurred over the years as mirrorless models have become more and more capable. Today, high-end mirrorless cameras better SLRs in autofocus performance and coverage, and typically offer a better experience when capturing video. From a physical standpoint, it's clear that Panasonic took it...
