Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 6 and the Ricoh GR III? 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

An illustration of the physical size and weight of the Leica D-LUX 6 and the Ricoh GR III is provided 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 size dimensions are rounded to the nearest millimeter.

The D-LUX 6 can be obtained in three different colors (black, silver, white), while the GR III is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR III is notably smaller (10 percent) than the Leica D-LUX 6. Moreover, the GR III is markedly lighter (14 percent) than the D-LUX 6. In this context, it is worth noting that neither the D-LUX 6 nor the GR III are weather-sealed.

Concerning battery life, the D-LUX 6 gets 330 shots out of its Leica BP-DC10 battery, while the GR III can take 200 images on a single charge of its Ricoh DB-110 power pack. The power pack in the GR III can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 D-LUX 6 was launched at a somewhat lower price (by 22 percent) than the GR III, which makes it more attractive for photographers on a tight budget. 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 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica D-LUX 6 features a 1/1.7-inch sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 774 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.5. The sensor in the D-LUX 6 has a native 4:3 aspect ratio, while the one in the GR III offers a 3:2 aspect. The D-LUX 6 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

With 24MP, the GR III offers a higher resolution than the D-LUX 6 (10MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.05μm for the D-LUX 6) due to its larger sensor. Moreover, the GR III is a much more recent model (by 6 years and 5 months) than the D-LUX 6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GR III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Leica D-LUX 6 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica D-LUX 6 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D-LUX 6 and the GR III are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the Visoflex (Typ 020) for the D-LUX 6 and the GV-1 for the GR III – are available as accessories. The adjacent table lists some of the other core features of the Leica D-LUX 6 and Ricoh GR III along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D-LUX 6 has one, while the GR III does not. While the built-in flash of the D-LUX 6 is not very powerful, it can at times be useful as a fill-in light.

The Leica D-LUX 6 and the Ricoh GR III both have 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 D-LUX 6 is equipped with a zoom lens, while the GR III comes with a built-in prime. The D-LUX 6 has a 24-90mm f/1.4-2.3 optic and the GR III offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Leica provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The D-LUX 6 offers the faster maximum aperture.

Concerning the storage of imaging data, both the D-LUX 6 and the GR III write their files to SDXC cards. The GR III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D-LUX 6 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 D-LUX 6 and Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D-LUX 6 does not provide wifi capability.

The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the D-LUX 6 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D-LUX 6 was succeeded by the Leica D-LUX Typ 109. Further information on the features and operation of the D-LUX 6 and GR III can be found, respectively, in the Leica D-LUX 6 Manual (free pdf) or the online Ricoh GR III Manual.

Review summary

So what is the bottom line? Is the Leica D-LUX 6 better than the Ricoh GR III or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Leica D-LUX 6:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Faster burst: Shoots at higher frequency (11 vs 4 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.4 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (330 versus 200) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced into a lower priced segment (22 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in September 2012).

Advantages of the Ricoh GR III:

• More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Is equipped with a larger and more technologically advanced 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.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More compact: Is smaller (109x62mm vs 111x68mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 41g or 14 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 6 years and 5 months of technical progress since the D-LUX 6 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GR III is the clear winner of the contest (17 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Leica D-LUX 6 and the Ricoh GR III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

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 D-LUX 6 or the GR III perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. 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.

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

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
