What you need to know about the new Leica M10-R Leica has just released a major update to the M10-series, with a big leap in resolution over the original M10 models. The new M10-R features a variant of the 40MP sensor found in the more recent 'Monochrom' version, and includes a couple of the nice extras introduced in the older 'P' model.
Read on to learn more.
New 40MP CMOS sensor
Externally, the only difference between the M10 and M10-R is the addition of an 'R' to the engraving on the hotshoe.
Internally, it's a different story. The M10-R offers a big jump in pixel count, from 24MP to 40MP. For anyone who was expecting the next-generation M to feature the 47MP sensor from the SL2 and Q2, we're told that the reason Leica opted for a 'color' version of the M10 Monochrom's 40MP sensor is simply size. The 40MP sensor is thinner, and better optimized for use in the compact body of the stills-only M10-series cameras.
Like the original M10, there's no option to shoot video. There's also no low-pass filter on the sensor, to really make the most out of all those pixels. The downside to that is that moir
Same processor, better high ISO and dynamic range
The M10-R's processor is the same Leica Maestro II that we've seen in previous M10-series models, but Leica claims that thanks to the new sensor, dynamic range has been substantially improved in Raw mode. Despite the significant increase in the size of its files, the M10-R's continuous shooting rate is 4. 5 fps – barely slower than the original M10's 4. 8 fps.
Like the original M10/P, native ISO sensitivity spans 100-50,000 (everything above 6400 is accessed via the 'M' setting on the ISO dial shown here) and the maximum exposure time has been extended to 16 minutes (from 4 minutes on the M10/M10-P).
Raw files are recorded in the DNG format, in 14-bit, with lossless compression.
Rangefinder focus system
Leica aficionados can skip this section, but for the uninitiated, the Leica M10-R is a rangefinder-type camera. It has an optical viewfinder, offering a comfortable field-of-view of approximately 28mm.
A series of prisms and mirrors under the top-plate (linked to a cam which connects to the lens) project two overlapping images into a small patch in the middle of the finder which, when they line up, indicate accurate focus. This was considered high technology in the 1920s, and still works well 100 years later, once you've got the hang of it.
Focus accuracy
One of the first questions I asked Leica representatives when they showed us the M10-R was whether the focusing system had been revisited to increase its accuracy, given the demands of a new 40MP sensor.
The answer I received was 'no'. The system was overhauled and improved for the original M10, and has not been tweaked since. From my shooting on the M10-R so far, focus accuracy is about what I'd expect from shooting with the original M10. When working wide-open, it's sensible (if you can) to focus bracket a little bit, but with practice, it's not too hard to get focus where you want it, in most situations – despite the higher pixel count. For critical work, the optional Typ 020 viewfinder (shown above on an M10) allows for precise manual focus.
Framelines
The approximate field of view your lens is indicated in the viewfinder using projected frame lines. You can preview the field-of-view provided different lenses (from 28mm to 135mm) by moving the lever below the viewfinder window (shown in the previous section of this article).
When you mount a different lens, the frame lines will automatically adjust accordingly. To accurately frame shots using lenses wider than 28mm, you'll need to attach an optical finder to the M10-R's hotshoe. This image shows how much the 75mm Summilux intrudes into the view, but it's an exception: most M-mount lenses don't take up this much visual real estate.
3", 1. 04M-dot touchscreen
The M10-R borrows from the M10-P in a couple of key respects, one being its touch-sensitive rear LCD. The touch functionality is well-implemented, to the extent that it doesn't get out of the way of the shooting experience. It's useful mostly for flipping through images in playback mode mode, and pinch-to-zoom to check focus. And you can tap as hard as you like – the screen is protected by Gorilla glass.
Touch-screen
It's a bit disappointing that there's no option to customize the touch function. It would be nice, for example, to be able to rate images by touch or use the screen as a focus point positioning pad with your eye to the (optional) EVF.
On the plus side, navigating through captured images and zooming in/out is very fast, with virtually no 'lag' despite the large file sizes. Please note that the image above shows the M10-P, and was taken at a time when we could still get friends to hold cameras for us from less than 6 feet away.
'Silent' shutter
The M10-R's 'silent' shutter is actually nothing of the sort, but rather the nicely-damped, very discreet mechanical shutter from the M10-P. While not silent, it is less obtrusive than the shutter sound of the original M10. There is no truly silent, fully electronic shutter mode available, in either normal or 'EVF' (live view) shooting.
Same old battery and memory card bay
No surprise here – the M10-R's battery and memory card are still accessed via a latched door on the base of the camera. Leica will tell you this is to help keep the camera sealed against dust and moisture (which is it, by the way) but we suspect that tradition plays a big part.
Having to remove the base of the camera to swap out a battery or SD card isn't the worst thing in the world, but it does make using the M10-R on a tripod (or even just in a soft case) more awkward than it probably needs to be. We had hoped for USB charging on this model, via a more-accessible port somewhere on the body but alas, tradition won the day, yet again. There's no official word on battery life, but we'd expect the M10-R to offer basically the same stamina as the M10 Monochrom (350-400 shots per charge).
The M10-R supports SD cards up to the SDXC standard. In other words, there's no benefit from using UHS-II cards in this camera. You can do it (and they're mechanically perfectly compatible), you just don't gain anything.
Leica FOTOS app
The M10-R is fully compatible with the FOTOS app, allowing for remote capture, image review and file transfer to a smart device. A fully-featured 'Pro' version of FOTUS is also available for iPad, for an annual fee. The app is shown here running alongside the weird and wonderful M10-D (which as you can see, doesn't have an LCD of its own).
The Leica M10-R is available in 'black chrome' and 'silver chrome', for an MSRP of $8,295 (the same price as the M10 Monochrom).
