Panasonic LX15 versus Sony RX10 IV

The Panasonic Lumix DMC-LX15 (called Panasonic LX10 in some regions) and the Sony Cyber-shot DSC-RX10 IV are two digital cameras that were officially introduced, respectively, in September 2016 and September 2017. Both the LX15 and the RX10 IV 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 RX10 IV

The physical size and weight of the Panasonic LX15 and the Sony RX10 IV 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 size dimensions 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 – the LX15 – represents 100 percent across all the size and weight measures).

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX15 was launched at a markedly lower price (by 59 percent) than the RX10 IV, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 RX10 IV

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. 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 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.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic LX15 and Sony RX10 IV 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 LX15 and the RX10 IV have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 IV is a somewhat more recent model (by 11 months) than the LX15, and its sensor might have benefitted from technological advances during this time.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).

 

Feature comparison: Panasonic LX15 vs Sony RX10 IV

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX10 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the LX15 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic LX15 and Sony RX10 IV along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the LX15 features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the LX15 and the RX10 IV have zoom lenses build in. The LX15 has a 24-72mm f/1.4-2.8 optic and the RX10 IV offers a 24-600mm f/2.4-4.0 (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 more tele-photo reach at the long end. The LX15 offers the faster maximum aperture.

Both the LX15 and the RX10 IV are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The LX15 replaced the earlier Panasonic LX7, while the RX10 IV followed on from the Sony RX10 III.

Review summary: Panasonic LX15 vs Sony RX10 IV

So what is the bottom line? Is the Panasonic LX15 better than the Sony RX10 IV or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Panasonic Lumix DMC-LX15:

  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.4 vs f/2.4).
  • More compact: Is smaller (106x60mm vs 133x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 785g or 72 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

ilogo

Arguments in favor of the Sony Cyber-shot DSC-RX10 IV:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (24 vs 10 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (400 versus 260) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Was introduced somewhat (11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 IV comes out slightly ahead of the LX15 (8 : 7 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 07:08 RX10 IV

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 RX10 IV. 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
