Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX10 III and the Panasonic Lumix DC-ZS200? 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 physical size and weight of the Sony RX10 III and the Panasonic ZS200 are illustrated in the side-by-side display below. 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.

The ZS200 can be obtained in two different colors (black, silver), while the RX10 III is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic ZS200 is considerably smaller (42 percent) than the Sony RX10 III. Moreover, the ZS200 is substantially lighter (68 percent) than the RX10 III. It is worth mentioning in this context that the RX10 III is splash and dust resistant, while the ZS200 does not feature any corresponding weather-sealing.

Concerning battery life, the RX10 III gets 420 shots out of its Sony NP-FW50 battery, while the ZS200 can take 370 images on a single charge of its Panasonic DMW-BLG10 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 ZS200 was launched at a markedly lower price (by 47 percent) than the RX10 III, which puts it into a different market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 RX10 III and the ZS200 have the same pixel density, as well as the same pixel size. It should, however, be noted that the ZS200 is a somewhat more recent model (by 1 year and 10 months) than the RX10 III, and its sensor might have benefitted from technological advances during this time.

The Sony Cyber-shot DSC-RX10 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The corresponding ISO settings for the Panasonic Lumix DC-ZS200 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the RX10 III is build around a BSI-CMOS sensor, while the ZS200 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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

One feature that is present on the RX10 III, but is missing on the ZS200 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 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, both cameras under consideration feature an 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 ZS200 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 RX10 III and the ZS200 have zoom lenses built in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the ZS200 offers a 24-360mm f/3.3-6.4 (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 ZS200 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-RX10 III and Panasonic Lumix DC-ZS200 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 III has a hotshoe, while the ZS200 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The ZS200 is a recent model that features in the current product line-up of Panasonic. In contrast, the RX10 III has been discontinued (but 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. Further information on the features and operation of the RX10 III and ZS200 can be found, respectively, in the Sony RX10 III Manual (free pdf) or the online Panasonic ZS200 Manual.

Review summary

So what is the bottom line? Is the Sony RX10 III better than the Panasonic ZS200 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Cyber-shot DSC-RX10 III:

• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.4 vs f/3.3).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Can take more shots (420 versus 370) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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).

Arguments in favor of the Panasonic Lumix DC-ZS200:

• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (111x65mm vs 133x94mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 711g or 68 percent) and is thus easier to take along.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 III is the clear winner of the match-up (13 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 RX10 III and the Panasonic ZS200 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the RX10 III and the ZS200 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
