Panasonic LX15 versus Sony RX100

The Panasonic Lumix DMC-LX15 (called Panasonic LX10 in some regions) and the Sony Cyber-shot DSC-RX100 are two digital cameras that were revealed to the public, respectively, in September 2016 and June 2012. Both the LX15 and the RX100 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: Panasonic LX15 vs Sony RX100

The physical size and weight of the Panasonic LX15 and the Sony RX100 are illustrated in the side-by-side display below. 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. 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 LX15 – represents 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 is notably smaller (7 percent) than the Panasonic LX15. Moreover, the RX100 is markedly lighter (23 percent) than the LX15. In this context, it is worth noting that neither the LX15 nor the RX100 are weather-sealed.

Concerning battery life, the LX15 gets 260 shots out of its DMW-BLH7 battery, while the RX100 can take 330 images on a single charge of its NP-BX1 power pack.

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 camera comparisons there.

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 RX100 was somewhat cheaper (by 7 percent) than the LX15 at launch, but both cameras fall into the same price category. 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: Panasonic LX15 vs Sony RX100

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. 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 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.

Sensor size

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 LX15 and the RX100 have the same pixel density, as well as the same pixel size. It should, however, be noted that the LX15 is much more recent (by 4 years and 3 months) than the RX100, and its sensor will have benefitted from technological advances during this time.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX15 provides a higher video resolution than the RX100. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison: Panasonic LX15 vs Sony RX100

Apart from body and sensor, cameras can and do differ across a variety of features. The LX15 and the RX100 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. The adjacent table lists some of the other core features of the Panasonic LX15 and Sony RX100 along with similar information for a selection of comparators.

Both the LX15 and the RX100 have zoom lenses build in. The LX15 has a 24-72mm f/1.4-2.8 optic and the RX100 offers a 28-100mm f/1.8-4.9 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end than the Sony, but less tele-photo reach at the long end. The LX15 offers the faster maximum aperture.

The LX15 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 was succeeded by the Sony RX100 II.

Review summary: Panasonic LX15 vs Sony RX100

So how do things add up? Is there a clear favorite between the Panasonic LX15 and the Sony RX100? The listing below highlights the relative strengths of the two models.


logo checkmark

Advantages of the Panasonic Lumix DMC-LX15:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • 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).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More modern: Reflects 4 years and 3 months of technical progress since the RX100 launch.

logo checkmark

Arguments in favor of the Sony Cyber-shot DSC-RX100:

  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Less heavy: Has a lower weight (by 70g or 23 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (330 versus 260) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in June 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the LX15 emerges as the winner of the contest (7 : 5 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 before making a camera decision.

LX15 07:05 RX100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the LX15 or the RX100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
