Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX100 III and the Panasonic Lumix DMC-FZ2000? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX100 III and the Panasonic FZ2000. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ2000 is considerably larger (138 percent) than the Sony RX100 III. Moreover, the FZ2000 is substantially heavier (216 percent) than the RX100 III. In this context, it is worth noting that neither the RX100 III nor the FZ2000 are weather-sealed.

Concerning battery life, the RX100 III gets 320 shots out of its Sony NP-BX1 battery, while the FZ2000 can take 350 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the RX100 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The RX100 III was launched at a markedly lower price (by 33 percent) than the FZ2000, 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.

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. 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 more expensive and 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.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the RX100 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 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.

The Sony Cyber-shot DSC-RX100 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Panasonic Lumix DMC-FZ2000 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the FZ2000 provides a better video resolution than the RX100 III. It can shoot movie 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. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the FZ2000 offers a substantially higher resolution than the one in the RX100 III (2360k vs 1440k dots). The adjacent table lists some of the other core features of the Sony RX100 III and Panasonic FZ2000 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The FZ2000 has a touchscreen, while the RX100 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the FZ2000 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic FZ2000 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both the RX100 III and the FZ2000 have zoom lenses built in. The RX100 III has a 24-70mm f/1.8-2.8 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 more tele-photo reach at the long end. The RX100 III offers the faster maximum aperture.

The RX100 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the FZ2000 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Cyber-shot DSC-RX100 III and Panasonic Lumix DMC-FZ2000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the FZ2000 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The RX100 III does not feature such a mic input.

The FZ2000 is a recent model that features in the current product line-up of Panasonic. In contrast, the RX100 III has been discontinued (but 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. Further information on the features and operation of the RX100 III and FZ2000 can be found, respectively, in the Sony RX100 III Manual (free pdf) or the online Panasonic FZ2000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony RX100 III and the Panasonic FZ2000? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

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

• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• More compact: Is smaller (102x58mm vs 138x102mm) and thus needs less room in the bag.

• More flexible LCD: Has a 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 (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Reflects 2 years and 4 months of technical progress since the RX100 III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the FZ2000 is the clear winner of the contest (14 : 8 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony RX100 III and the Panasonic FZ2000 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the RX100 III and the FZ2000 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.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
