Leica C-LUX vs Sony RX100 III
The Leica C-LUX and the Sony Cyber-shot DSC-RX100 III are two digital cameras that were revealed to the public, respectively, in June 2018 and May 2014. Both the C-LUX and the RX100 III are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixels.
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 C-LUX and the Sony Cyber-shot DSC-RX100 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.
The physical size and weight of the Leica C-LUX and the Sony RX100 III 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 width, height and depth dimensions are rounded to the nearest millimeter.
The C-LUX can be obtained in two different colors (gold, blue), while the RX100 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 Sony RX100 III is notably smaller (22 percent) than the Leica C-LUX. Moreover, the RX100 III is markedly lighter (15 percent) than the C-LUX. In this context, it is worth noting that neither the C-LUX nor the RX100 III are weather-sealed.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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 RX100 III was launched at a somewhat lower price (by 24 percent) than the C-LUX, 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.
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 associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the C-LUX and the RX100 III have the same pixel density, as well as the same pixel size. It should, however, be noted that the C-LUX is much more recent (by 4 years and 1 month) than the RX100 III, and its sensor will have benefitted from technological advances during this time.
The Leica C-LUX has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the C-LUX provides a higher video resolution than the RX100 III. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the C-LUX offers a substantially higher resolution than the one in the RX100 III (2330k vs 1440k dots). The adjacent table lists some of the other core features of the Leica C-LUX and Sony RX100 III along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The C-LUX has a touchscreen, while the RX100 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The RX100 III has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the C-LUX does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the C-LUX is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Leica C-LUX 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.
Both the C-LUX and the RX100 III have zoom lenses built in. The C-LUX has a 24-360mm f/3.3-6.4 optic and the RX100 III offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Leica and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 III offers the faster maximum aperture.
The C-LUX writes its imaging data to SDXC cards, while the RX100 III uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 C-LUX and Sony Cyber-shot DSC-RX100 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The C-LUX is a recent model that features in the current product line-up of Leica. In contrast, the RX100 III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 III was succeeded by the Sony RX100 IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Sony websites.
So what conclusions can be drawn? Is the Leica C-LUX better than the Sony RX100 III or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Leica C-LUX:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2330k vs 1440k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.22x).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Can take more shots (370 versus 320) on a single battery charge.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 4 years and 1 month of technical progress since the RX100 III launch.
Arguments in favor of the Sony Cyber-shot DSC-RX100 III:
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.3).
- More compact: Is smaller (102x58mm vs 113x67mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 50g or 15 percent) and is thus easier to take along.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was released into a lower priced segment (24 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in May 2014).
If the count of relative strengths (bullet points above) is taken as a measure, the C-LUX emerges as the winner of the contest (10 : 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 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.
How about other alternatives? Do the specifications of the Leica C-LUX and the Sony RX100 III place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the C-LUX or the RX100 III 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
