Panasonic LX10 versus Sony RX100 III

The Panasonic Lumix DMC-LX10 (called Panasonic LX15 in some regions) and the Sony Cyber-shot DSC-RX100 III are two digital cameras that were officially introduced, respectively, in September 2016 and May 2014. Both the LX10 and the RX100 III are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

An illustration of the physical size and weight of the Panasonic LX10 and the Sony RX100 III is provided in the side-by-side display below. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the LX10 – represents the basis or 100 percent across all the size and weight measures).

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 somewhat smaller (7 percent) than the Panasonic LX10. Moreover, the RX100 III is slightly lighter (6 percent) than the LX10. In this context, it is worth noting that neither the LX10 nor the RX100 III are weather-sealed.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed 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

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.

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 megapixel. This similarity in sensor specs implies that both the LX10 and the RX100 III 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.

For most 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX10 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.

Feature comparison

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 Panasonic LX10, the Sony RX100 III, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

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

Summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic LX10 and the Panasonic LX10? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-LX10:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.4 vs f/1.8).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Reflects 2 years and 4 months of technical progress since the RX100 III launch.

Reasons to prefer the Sony Cyber-shot DSC-RX100 III:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Longer lasting: Gets more shots (320 versus 260) out of a single battery charge.
  • 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 LX10 is the clear winner of the match-up (8 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

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 LX10 and the RX100 III in practical situations. 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
