Leica M10 vs. Leica M10-R: What's the Difference?

The Leica M10 and M10-R look almost identical. Same M-body build, same manual-focus rangefinder experience, and the same Leica M lens mount. The primary difference is in the sensor. The original M10 uses a 24-megapixel full-frame CMOS sensor, while the M10-R increases resolution with a 40-megapixel full-frame CMOS sensor, but there’s more to consider than just 24 vs. 40 megapixels.

The Leica M10

Introduced in 2017, the M10 was a significant redesign of Leica’s digital M. Its body is noticeably slimmer than the previous M Typ 240, bringing the dimensions closer to those of Leica’s classic film M cameras. The M10 pairs its 24mp sensor with Leica’s Maestro II processor and offers an ISO range of 100–50,000. It also introduced a dedicated ISO dial on the top plate, joining the shutter-speed and aperture controls to make the basic exposure settings accessible without having to access the menu.

It’s a very capable sensor by modern standards. Twenty-four megapixels is plenty for most photography, and the relatively manageable file size make the M10 a practical camera for shooting, editing, and storing a lot of images. Because this is an M (for "Messsucher" the German word for rangefinder or literally "measuring finder"), there’s no autofocus and no electronic viewfinder built into the body. Focusing is done through Leica’s traditional coupled optical rangefinder. The M10 does add Live View on its rear LCD, however, and it can accept an optional Visoflex electronic viewfinder.

Then Came the M10-R

Leica introduced the M10-R in 2020, retaining essentially the same M10 body and shooting experience but replacing the 24mp sensor with a new 40mp CMOS sensor. That extra resolution is the headline feature, and it makes a meaningful difference. The M10-R records substantially more fine detail, gives you more room to crop, and provides considerably more resolution for large prints. Leica accomplished the increase in resolution while maintaining the look and user experience of the M10. If you’re already comfortable with an M10, picking up an M10-R does not feel noticeably different. 

Leica also improved the sensor’s dynamic range compared with the original M10, giving the M10-R more latitude for preserving detail in bright highlights and deep shadows. While the increased resolution gets a lot of attention, for us it's the increase in dynamic range that really sets the M10-R apart from its predecessor. 

Which One Should You Buy?

Both cameras give you essentially the same fundamental Leica M experience: an optical rangefinder, manual focusing, direct physical exposure controls, compact M lenses, and very few distractions between you and making a photograph. Neither camera is trying to compete with a modern mirrorless body on autofocus speed, burst rates, video features, or computational photography. That’s not really the point. You’re still focusing through a rangefinder patch. You’re still selecting the aperture on the lens. And you’re still working with a camera design whose basic operating principles stretch back decades.

If you're shooting landscape, architecture, fine-art work, making large prints, or cropping heavily, the 40mp sensor M10-R will be a better fit. It provides significantly more detail and cropping flexibility while preserving almost everything people like about the original M10. If you're looking for an everyday carry to capture scenes in harsh or low light conditions, the improved dynamic range of the M10-R should also be a consideration. 

The regular M10, however, can be the better value. You’re getting essentially the same body, rangefinder, controls, and overall shooting experience with a 24mp sensor that’s still more than capable for most photographers. Without question, the M10 is still an exceptional camera- and for some, especially those who prefered a smaller file size, it might be the better choice.

In other words, this isn’t really a choice between an outdated camera and a newer one. It’s a choice between 24mp and 40mp versions of one of Leica’s best digital M designs. If you need the extra resolution, the M10-R delivers it. If you don’t, the original M10 won't leave you disappointed.
