Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M10-R and the Nikon Coolpix B600? 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 side-by-side display below illustrates the physical size and weight of the Leica M10-R and the Nikon B600. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The M10-R can be obtained in two different colors (black, silver), while the B600 is also available in two color-versions, but different ones (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon B600 is notably smaller (10 percent) than the Leica M10-R. It is worth mentioning in this context that the M10-R is splash and dust resistant, while the B600 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the B600 has a lens built in, whereas the M10-R 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-R and their specifications in the Leica M Lens Catalog.

Concerning battery life, the M10-R gets 210 shots out of its Leica BP-SCL5 battery, while the B600 can take 280 images on a single charge of its Nikon EN-EL12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The B600 was launched at a lower price than the M10-R, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M10-R features a full frame sensor and the Nikon B600 a 1/2.3-inch sensor. The sensor area in the B600 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the M10-R has a native 3:2 aspect ratio, while the one in the B600 offers a 4:3 aspect.

With 40.9MP, the M10-R offers a higher resolution than the B600 (15.9MP), but the M10-R nevertheless has larger individual pixels (pixel pitch of 4.57μm versus 1.33μm for the B600) due to its larger sensor. Moreover, the M10-R is a somewhat more recent model (by 1 year and 5 months) than the B600, and its sensor might 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 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-R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-R for good quality output (200 dots per inch) amounts to 39.3 x 26 inches or 99.9 x 66 cm, for very good quality (250 dpi) 31.5 x 20.8 inches or 79.9 x 52.8 cm, and for excellent quality (300 dpi) 26.2 x 17.3 inches or 66.6 x 44 cm. The corresponding values for the Nikon B600 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Leica M10-R has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Nikon Coolpix B600 are ISO 125 to ISO 6400 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The B600 indeed provides for movie recording, while the M10-R does not. The highest resolution format that the B600 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the M10-R has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the B600 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Leica M10-R and Nikon B600 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10-R has a touchscreen, while the B600 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Leica M10-R 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.

Concerning the storage of imaging data, both the M10-R and the B600 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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-R and Nikon Coolpix B600 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10-R has a hotshoe, while the B600 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the M10-R and the B600 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Leica and Nikon. Further information on the features and operation of the M10-R and B600 can be found, respectively, in the Leica M10-R Manual (free pdf) or the online Nikon B600 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica M10-R or the Nikon B600 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Leica M10-R:

• More detail: Offers more megapixels (40.9 vs 15.9MP) with a 64% higher linear resolution.
• 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.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• 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.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 1 year and 5 months after the B600).

Reasons to prefer the Nikon Coolpix B600:

• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Faster burst: Shoots at higher frequency (7.4 vs 4.5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has an integrated lens, whereas the M10-R necessitates an extra lens.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the M10-R).
• Longer lasting: Gets more shots (280 versus 210) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in January 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the M10-R is the clear winner of the match-up (14 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 incomplete and does no justice, for example, to the way the M10-R or the B600 perform in practice. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
