Sony RX100 III versus Panasonic LX10

The Sony Cyber-shot DSC-RX100 III and the Panasonic Lumix DMC-LX10 (labelled Panasonic LX15 in some countries) are two digital cameras that were officially introduced, respectively, in May 2014 and September 2016. Both the RX100 III and the LX10 are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony RX100 III vs Panasonic LX10

The side-by-side display below illustrates the physical size and weight of the Sony RX100 III and the Panasonic LX10. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the RX100 III – represents the basis for the calculations across all the size and weight measures).

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX10 was launched at a somewhat lower price (by 13 percent) than the RX100 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: Sony RX100 III vs Panasonic LX10

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

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.

Sony RX100 III and Panasonic LX10 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the RX100 III and the LX10 have the same pixel density, as well as the same pixel size. It should, however, be noted that the LX10 is much more recent (by 2 years and 4 months) than the RX100 III, and its sensor will have benefitted from technological advances during this time.

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 LX10 provides a better video resolution than the RX100 III. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison: Sony RX100 III vs Panasonic LX10

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 III has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the LX10 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony RX100 III, the Panasonic LX10, and comparable cameras.

Both the RX100 III and the LX10 have zoom lenses build in. The RX100 III has a 24-70mm f/1.8-2.8 optic and the LX10 offers a 24-72mm f/1.4-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony and Panasonic provide the same view at the wide-angle end, but the Panasonic has more tele-photo reach at the long end. The LX10 offers the faster maximum aperture.

The LX10 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 III has been discontinued (but it 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.

RX100 III 04:07 LX10

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 III and the LX10 in practical situations. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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.
