Leica M10

Introduced in January 17, 2017³³⁴
4mm thinner than M (Typ 240)³⁰⁹
deeper lens mount than M (Typ 240), which accounts for about half of the overall thickness difference³⁰⁹.
the thumb grip slightly deeper than M (Typ 240)³⁰⁹
50 grams lighter than M (Typ 240)³⁰⁹
Weight 647 grams³⁰⁹
The rangefinder on the M10 has been completely redesigned and is now 30% larger than that on M240³⁰⁹
It has a magnification of 0.73, compared to the 0.68 found in earlier digital M models. This larger rangefinder allows for much easier visibility of the 28mm framelines compared to M240, while the higher magnification simplifies focusing³⁰⁹.
Leica has not disclosed the manufacturer of the M10's sensor³⁰⁹
it is a new sensor made specifically for the M10. The M10 boasts a maximum ISO of 50,000, which is three stops more than the maximum ISO of 6,400 found in M240. The improved dynamic range and minimized banding, along with excellent color reproduction, make the higher ISO values quite usable³⁰⁹.
The M10 is equipped with a Maestro II processor, designed to produce less heat and consume less battery power³⁰⁹.
Due to the thinner body of the M10, a completely new shutter design was necessary. It has a sound that is very similar to that of M240: no louder, but slightly higher in pitch³⁰⁹.
The LCD on the M10 is 3 inches, similar to that of M240, but it features greater resolution (1036 vs. 920) and a different aspect ratio. The screen is clear and bright, making it excellent for both live view and image reviews³⁰⁹.
The top plate of the M10 now includes an ISO dial and has removed the video button and the multi-function On/Off switch. The rear plate has a slightly redesigned thumb wheel and direction rocker switch. However, the most significant changes can be found in the buttons on the left side of the LCD³⁰⁹.
With the introduction of the M10 in 2017, Leica returned to its previous approach to camera naming conventions. Although it maintained a resolution of around 24 megapixels, the image sensor of the M10 offered significantly higher sensitivity, boasting a theoretical maximum ISO value of 50,000. This sensor advancement provided a noticeable improvement in image quality compared to its predecessors, which may not be immediately apparent from the technical specifications³⁵⁷.
Moreover, Leica M photographers welcomed the M10's new housing featuring a redesigned top plate, reminiscent of the legendary M3. The M10 was also the first digital M model to incorporate a dedicated ISO dial, replacing the traditional rewind button found on older analog M models. This innovation, conceived by the product management team led by Jesko von Oeynhausen, allowed users to control all key parameters—focus, aperture, shutter speed, and ISO settings—directly on the camera without having to navigate through menus. As is often the case with Leica's M series, these seemingly minor yet practical details have significantly contributed to the M10's lasting popularity³⁵⁷.
The Leica M10 was a completely new development and the first M model to revert to the old naming scheme. While it featured the same 24-megapixel CMOS image sensor typical of its predecessors, its enhanced sensitivity enabled a marked improvement in picture quality. Additionally, the M10 included a sensitivity dial, reducing the need to search through camera menus³⁵⁷.
The digital capabilities of the M10 were further enhanced by the integration of a WLAN module, allowing the camera to connect to the Leica FOTOS app on smartphones. This feature enabled users to upload images and control the camera remotely. An additional GPS receiver was integrated into the redesigned electronic Visoflex viewfinder, whose connection pins were discreetly relocated to the accessory shoe³⁵⁷.
The Leica M10 also included Live View but did not offer a video mode, maintaining a clear focus on photography while providing optional image composition on the display. Its housing was extensively redesigned to accommodate the newly arranged control elements while moving closer to the classic, less bulky form factor of the analog rangefinder models³⁵⁷.
