Sony RX10 III versus Panasonic FZ330
The Sony Cyber-shot DSC-RX10 III and the Panasonic Lumix DMC-FZ330 (labelled Panasonic FZ300 in some countries) are two digital cameras that were officially introduced, respectively, in March 2016 and July 2015. Both the RX10 III and the FZ330 are fixed lens compact cameras that are based on an one-inch (RX10 III) and sensor. The Sony has a resolution of 20 megapixel, whereas the Panasonic provides 12 MP.
An illustration of the physical size and weight of the Sony RX10 III and the Panasonic FZ330 is provided in the side-by-side display below. 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 use the toggle button 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 side – the RX10 III – represents the basis for the calculations 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 FZ330 is somewhat smaller (3 percent) than the Sony RX10 III. Moreover, the FZ330 is markedly lighter (34 percent) than the RX10 III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The FZ330 was launched at a markedly lower price (by 60 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony RX10 III features an one-inch sensor and the Panasonic FZ330 sensor. The sensor area in the FZ330 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the RX10 III has a native 3:2 aspect ratio, while the one in the FZ330 offers a 4:3 aspect.
With 20MP, the RX10 III offers a higher resolution than the FZ330 (12MP), but the RX10 III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the FZ330) due to its larger sensor. Moreover, the RX10 III is a somewhat more recent model (by 8 months) than the FZ330, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the FZ330 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the RX10 III provides substantially higher image quality than the FZ330, with an overall score that is 32 points higher. This advantage is based on 3.8 bits higher color depth, 1.6 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the RX10 III offers a substantially higher resolution than the one in the FZ330 (2359k vs 1440k dots). The table below summarizes some of the other core capabilities of the Sony RX10 III and Panasonic FZ330 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the RX10 III and the FZ330 have zoom lenses build in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the FZ330 offers a 25-600mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Panasonic and the same tele-photo reach at the long end. The RX10 III offers the faster maximum aperture.
The FZ330 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.
So what is the bottom line? Is the Sony RX10 III better than the Panasonic FZ330 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Sony Cyber-shot DSC-RX10 III:

- More heavily discounted: Has been on the market for longer (launched in March 2016).
If the number of relative strengths (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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the RX10 III or the FZ330 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
