Leica M10-P vs X1

The Leica M10-P and the Leica X1 are two digital cameras that were revealed to the public, respectively, in August 2018 and September 2009. The M10-P is a rangefinder-focusing mirrorless camera, while the X1 is a fixed lens compact. The cameras are based on a full frame (M10-P) and an APS-C (X1) sensor. The M10-P has a resolution of 23.8 megapixels, whereas the X1 provides 12.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M10-P and the Leica X1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Leica M10-P and the Leica X1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica X1 is considerably smaller (33 percent) than the Leica M10-P. It is worth mentioning in this context that the M10-P is splash and dust resistant, while the X1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X1 has a lens built in, whereas the M10-P is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the M10-P and their specifications in the Leica M Lens Catalog.

Concerning battery life, the M10-P gets 210 shots out of its Leica BP-SCL5 battery, while the X1 can take 260 images on a single charge of its Leica BP-DC8 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X1 was launched at a lower price than the M10-P, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M10-P features a full frame sensor and the Leica X1 an APS-C sensor. The sensor area in the X1 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 23.8MP, the M10-P offers a higher resolution than the X1 (12.2MP), but the M10-P nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 5.51μm for the X1) due to its larger sensor. Moreover, the M10-P is a much more recent model (by 8 years and 11 months) than the X1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the M10-P has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M10-P implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-P for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 cm. The corresponding values for the Leica X1 are 21.4 x 14.3 inches or 54.3 x 36.3 cm for good quality, 17.1 x 11.4 inches or 43.4 x 29 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.2 cm for excellent quality prints.

The Leica M10-P has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Leica X1 are ISO 100 to ISO 3200 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the M10-P has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Leica M10-P, the Leica X1, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10-P has a touchscreen, while the X1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Leica M10-P has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The M10-P writes its imaging data to SDXC cards, while the X1 uses SDHC cards. The M10-P supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X1 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Leica M10-P and Leica X1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10-P offers wifi support, while the X1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the M10-P and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the M10-P does not have a direct successor. Further information on the features and operation of the M10-P and X1 can be found, respectively, in the Leica M10-P Manual (free pdf) or the online Leica X1 Manual.

Review summary

So how do things add up? Which of the two cameras – the Leica M10-P or the Leica X1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica M10-P:

• More detail: Offers more megapixels (23.8 vs 12.2MP) with a 39% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 8 years and 11 months of technical progress since the X1 launch.

Reasons to prefer the Leica X1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Ready to shoot: Has an integrated lens, whereas the M10-P necessitates an extra lens.
• More compact: Is smaller (124x60mm vs 139x80mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the M10-P).
• Longer lasting: Gets more shots (260 versus 210) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the M10-P is the clear winner of the match-up (18 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M10-P or the X1. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
