Sony RX100 II versus Panasonic LX15

The Sony Cyber-shot DSC-RX100 II and the Panasonic Lumix DMC-LX15 (labelled Panasonic LX10 in some countries) are two digital cameras that were revealed to the public, respectively, in June 2013 and September 2016. Both the RX100 II and the LX15 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 Sony RX100 II and the Panasonic LX15 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 RX100 II – 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 Panasonic LX15 is somewhat larger (8 percent) than the Sony RX100 II. Moreover, the LX15 is markedly heavier (10 percent) than the RX100 II. In this context, it is worth noting that neither the RX100 II nor the LX15 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.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX15 was somewhat cheaper (by 7 percent) than the RX100 II 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

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.

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 RX100 II and the LX15 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 3 years and 2 months) than the RX100 II, 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 better video resolution than the RX100 II. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The RX100 II and the LX15 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 Sony RX100 II and Panasonic LX15 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the RX100 II and the LX15 have zoom lenses build in. The RX100 II has a 28-100mm f/1.8-4.9 optic and the LX15 offers a 24-72mm f/1.4-2.8 (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 II has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 II was succeeded by the Sony RX100 III.

Summary

So what is the bottom line? Which of the two cameras – the Sony RX100 II or the Panasonic LX15 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of the Sony Cyber-shot DSC-RX100 II:

  • 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.
  • Longer lasting: Can take more shots (350 versus 260) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in June 2013).

logo checkmark

Arguments in favor of the Panasonic Lumix DMC-LX15:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • 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.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Reflects 3 years and 2 months of technical progress since the RX100 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the LX15 emerges as the winner of the match-up (7 : 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX100 II or the LX15. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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.
