Leica Camera has updated its M System, introducing the Leica M10 – price tag £5600 – with a release date set for 19 January 2017.

The Leica M10 rangefinder is the slimmest digital M System camera the company has released, with a new ergonomic body design reminiscent of its analogue forebears.

The Leica M10’s top plate measures just 33.75mm – 4mm less than its closest relative, the Leica M (Typ 240).

Leica says it has also improved the photographer’s view of the subject being captured by enlarging the M10’s field of view by 30%. Leica says it has also increased the magnification factor to 0.73.

And good news for photographers who wear glasses, Leica says the viewfinder is much more comfortable to use because it has increased the optimum distance of the eye from the viewfinder eyepiece by 50%.

On the back of the Leica M10 is a single joystick control and three buttons for Play, Live View and Menu. Particular settings can be selected according to personal preferences and photographic needs via a freely-configurable Favourites Menu.

Inside the new Leica camera is a 24-megapixel, full-frame CMOS sensor developed specifically for the M10. Leica says this new sensor promises “impressive dynamic range, excellent contrast rendition, exceptional sharpness and fine detail resolution.”

This is thanks for a pixel and micro-lens architecture that, according to Leica, “enables a particularly large aperture, ensuring rays of light hitting the sensor even from the most oblique angles are precisely captured by its photodiodes.”

Leica says a new glass cover plate over the sensor acts as an infrared cut-off filter, protecting images from refraction of incoming light.

We’ve put these claims to the test in our Leica M10 review.

Meanwhile, the Leica M10 – like many new cameras these days – has no anti-aliasing filter to allow the new Leica camera to capture finer details.

What’s more, the Leica M10’s new sensor allows for a native sensitivity range from ISO 100 up to ISO 50,000, with better noise control at the higher end, Leica says.

Other new features include Leica’s Maestro II image processor, which gives the camera 2GB buffer memory and the capability to shoot up to 5fps at full resolution in burst mode.

Leica says the Maestro II processor allows a new loupe function for checking image sharpness to be used both on the camera’s LCD screen and in conjunction with the Visoflex electronic viewfinder with 2.4-megapixel resolution.

The Leica M10 viewfinder also boasts a swivel function and an integrated GPS module for the geotagging of image files.

The Leica M10 is also the first Leica M System camera to feature built-in Wi-Fi capability. The M10’s WLAN connectivity allows photographers to Apple mobile devices.

The Leica M-App also allows the direct transfer of RAW data in DNG format to mobile devices for further processing with suitable apps from iOS Version 10.2. The Leica M10 can also be remotely controlled by WLAN from a smartphone or tablet.

For metering on the sensor: spot, centre-weighted, multi-field metering

Metering range
At room temperature and normal humidity at ISO 100, at aperture 1.0 EV-1 to EV20 at aperture 32. Flashing of the left triangular LED in the viewfinder indicates values below the metering range

Sensitivity range
ISO 100 to ISO 50,000, adjustable in 1/3 ISO increments from ISO 200, choice of automatic control or manual setting

Exposure modes
Choice of automatic shutter speed control with manual aperture preselection – aperture priority A, or manual shutter speed and aperture setting

Flash unit attachment
Via accessory shoe with central and control contacts

Synchronisation
Optionally triggered at the 1st or 2nd shutter curtain

Flash sync time
1/180 s ; slower shutter speeds can be used, if working below sync speed: Automatic changeover to TTL linear flash mode with HSS-compatible Leica system flash units

Flash exposure metering
Using centre-weighted TTL pre-flash metering with Leica flash units (SF40, SF64, SF26), or flash units compatible with the system with SCA3502 M5 adapter

Parallax compensation
The horizontal and vertical difference between the viewfinder and the lens is automatically compensated according to the relevant distance setting, i.e. the viewfinder bright-line automatically aligns with the subject detail recorded by the lens
