Sony RX10 III versus Panasonic FZ2000

The Sony Cyber-shot DSC-RX10 III and the Panasonic Lumix DMC-FZ2000 (labelled Panasonic FZ2500 in some countries) are two digital cameras that were revealed to the public, respectively, in March 2016 and September 2016. Both the RX10 III and the FZ2000 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.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The FZ2000 was launched at a somewhat lower price (by 20 percent) than the RX10 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 RX10 III vs Panasonic FZ2000

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

Sony RX10 III and Panasonic FZ2000 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 RX10 III and the FZ2000 have the same pixel density, as well as the same pixel size. It should, however, be noted that the FZ2000 is a somewhat more recent model (by 5 months) than the RX10 III, and its sensor might have benefitted from technological advances during this time.

One feature that is present on the RX10 III, but is missing on the FZ2000 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the FZ2000 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the RX10 III and the FZ2000 have zoom lenses build in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the FZ2000 offers a 24-480mm f/2.8-4.5 (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 less tele-photo reach at the long end. The RX10 III offers the faster maximum aperture.

The RX10 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the FZ2000 uses SDXC cards.

The FZ2000 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX10 III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX10 III was succeeded by the Sony RX10 IV.

Review summary: Sony RX10 III vs Panasonic FZ2000

So what conclusions can be drawn? Is the Sony RX10 III better than the Panasonic FZ2000 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

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

  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (14 vs 12 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.4 vs f/2.8).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (133x94mm vs 138x102mm) and thus needs less room in the bag.
  • Longer lasting: Can take more shots (420 versus 350) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in March 2016).

ilogo

Reasons to prefer the Panasonic Lumix DMC-FZ2000:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Less heavy: Has a lower weight (by 136g or 13 percent) and is thus easier to take along.
  • More affordable: Was released into a lower priced segment (20 percent cheaper at launch).
  • More modern: Was introduced somewhat (5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 III emerges as the winner of the contest (10 : 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.

RX10 III 10:07 FZ2000

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the RX10 III or the FZ2000 handle or perform in practice. 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 where reviews by experts come in. 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
