Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 and the Sony Cyber-shot DSC-RX1? 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 D-LUX 5 and the Sony RX1. 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 measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1 is somewhat larger (3 percent) than the Leica D-LUX 5. Moreover, the RX1 is substantially heavier (78 percent) than the D-LUX 5. In this context, it is worth noting that neither the D-LUX 5 nor the RX1 are weather-sealed.

Concerning battery life, the D-LUX 5 gets 400 shots out of its Leica BP-DC10 battery, while the RX1 can take 270 images on a single charge of its Sony NP-BX1 power pack. The power pack in the RX1 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. 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 D-LUX 5 was launched at a markedly lower price (by 75 percent) than the RX1, which puts it into a different market segment. 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 imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 5 features a 1/1.7-inch sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 1752 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 1.0. The sensor in the D-LUX 5 has a native 4:3 aspect ratio, while the one in the RX1 offers a 3:2 aspect. The D-LUX 5 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 RX1 offers a higher resolution than the D-LUX 5 (10MP), but the RX1 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 2.14μm for the D-LUX 5) due to its larger sensor. Moreover, the RX1 is a somewhat more recent model (by 1 year and 11 months) than the D-LUX 5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony RX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1 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 5 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 Leica D-LUX 5 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the D-LUX 5 is build around a CCD sensor, while the RX1 uses a CMOS 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX1 provides a better video resolution than the D-LUX 5. It can shoot movie footage at 1080/60p, while the Leica is limited to 720/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D-LUX 5 and the RX1 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 EVF1 for the D-LUX 5 and the FDA-EV1MK for the RX1 – are available as accessories. The table below summarizes some of the other core capabilities of the Leica D-LUX 5 and Sony RX1 in connection with corresponding information for a sample of similar cameras.

The D-LUX 5 is equipped with a zoom lens, while the RX1 comes with a built-in prime. The D-LUX 5 has a 24-90mm f/2.0-3.3 optic and the RX1 offers a 35mm f/2.0 (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 Sony. Both cameras offer the same maximum aperture.

The D-LUX 5 writes its imaging data to SDXC cards, while the RX1 uses SDXC or Memory Stick PRO Duo 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 5 and Sony Cyber-shot DSC-RX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The D-LUX 5 does not feature such a mic input.

Both the D-LUX 5 and the RX1 have been discontinued, but can regularly be found used on ebay. The D-LUX 5 was replaced by the Leica D-LUX 6, while the RX1 was followed by the Sony RX1R. Further information on the features and operation of the D-LUX 5 and RX1 can be found, respectively, in the Leica D-LUX 5 Manual (free pdf) or the online Sony RX1 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Leica D-LUX 5 or the Sony RX1 – 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 D-LUX 5:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Less heavy: Is lighter (by 211g or 44 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (400 versus 270) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2010).

Arguments in favor of the Sony Cyber-shot DSC-RX1:

• More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
• 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 video: Provides higher definition movie capture (1080/60p vs 720/60p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
• Faster burst: Shoots at higher frequency (5 vs 2.5 flaps/sec) to capture the decisive moment.
• Easier travel charging: Can be conveniently charged via its USB port.
• More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the RX1 emerges as the winner of the match-up (11 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 5 and the Sony RX1 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D-LUX 5 or the RX1. 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 expert reviews 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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
