Leica M10 vs M8

The Leica M10 (Typ 3656) and the Leica M8 are two enthusiast cameras that were announced, respectively, in January 2017 and September 2006. Both the M10 and the M8 are rangefinder-focusing mirrorless cameras that are based on a full frame (M10) and an APS-H (M8) sensor. The M10 has a resolution of 23.8 megapixels, whereas the M8 provides 10.4 MP.

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

Body comparison

The physical size and weight of the Leica M10 and the Leica M8 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

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

Size Leica M10 vs Leica M8
Compare M10 versus M8 top
Comparison M10 or M8 rear

In this particular case, the Leica M10 and the Leica M8 have exactly the same width and height, and, thus, have identically-sized bodies. However, the M8 is markedly lighter (10 percent) than the M10. It is worth mentioning in this context that the M10 is splash and dust resistant, while the M8 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor (as in the M10) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (M8). You can compare the optics available in the Leica M Lens Catalog.

Concerning battery life, the M10 gets 210 shots out of its Leica BP-SCL5 battery, while the M8 can take 550 images on a single charge of its Leica BLI-312 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M8 was launched at a somewhat lower price (by 17 percent) than the M10, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 features a full frame sensor and the Leica M8 an APS-H sensor. The sensor area in the M8 is 43 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica M10 and Leica M8 sensor measures

With 23.8MP, the M10 offers a higher resolution than the M8 (10.4MP), but the M10 has smaller individual pixels (pixel pitch of 6.00μm versus 6.84μm for the M8). However, the M10 is a much more recent model (by 10 years and 4 months) than the M8, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 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 M8 are 19.7 x 13.2 inches or 50 x 33.4 cm for good quality, 15.7 x 10.5 inches or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inches or 33.3 x 22.3 cm for excellent quality prints.

The Leica M10 (Typ 3656) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Leica M8 are ISO 160 to ISO 2500 (no boost).

In terms of underlying technology, the M10 is build around a CMOS sensor, while the M8 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

M10 versus M8 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the M10 provides substantially higher image quality than the M8, with an overall score that is 27 points higher. This advantage is based on 3.3 bits higher color depth, 1.9 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

It is notable that the M10 offers wifi support, while the M8 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the M10 and the M8 have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the M10 was followed by the Leica M11. Further information on the features and operation of the M10 and M8 can be found, respectively, in the Leica M10 Manual (free pdf) or the online Leica M8 Manual.

Review summary

So what is the bottom line? Is the Leica M10 better than the Leica M8 or vice versa? The listing below highlights the relative strengths of the two models.


Advantages of the Leica M10 (Typ 3656):

  • More detail: Offers more megapixels (23.8 vs 10.4MP) with a 51% higher linear resolution.
  • Better image quality: Scores substantially higher (27 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (3.3 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.9 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
  • Faster burst: Shoots at higher frequency (5 vs 2 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • 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 10 years and 4 months of technical progress since the M8 launch.


Arguments in favor of the Leica M8:

  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Longer lasting: Gets more shots (550 versus 210) out of a single battery charge.
  • More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the M10 is the clear winner of the match-up (13 : 4 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.

M10 13:04 M8

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 or the M8. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
