Sony RX10 III versus Panasonic FZ1000

The Sony Cyber-shot DSC-RX10 III and the Panasonic Lumix DMC-FZ1000 are two digital cameras that were officially introduced, respectively, in March 2016 and June 2014. Both the RX10 III and the FZ1000 are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The physical size and weight of the Sony RX10 III and the Panasonic FZ1000 are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX10 III – represents 100 percent across all the size and weight measures).

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The FZ1000 was launched at a markedly lower price (by 40 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.

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. 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 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.

Sensor size

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 FZ1000 have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 III is a somewhat more recent model (by 1 year and 9 months) than the FZ1000, and its sensor might have benefitted from technological advances during this time.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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"). Of the two cameras under review, the RX10 III has a notably higher overall DXO score than the FZ1000 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.9 EV in additional dynamic range, 0.1 stops of reduced 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 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

Beyond body and sensor, cameras can and do differ across a range of features. The RX10 III and the FZ1000 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2359k dots. The adjacent table lists some of the other core features of the Sony RX10 III and Panasonic FZ1000 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.

Both the RX10 III and the FZ1000 have zoom lenses build in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the FZ1000 offers a 25-400mm f/2.8-4.0 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Panasonic. The RX10 III offers the faster maximum aperture.

Both the RX10 III and the FZ1000 have been discontinued, but can regularly be found used on ebay. The FZ1000 was replaced by the Panasonic FZ2500, while the RX10 III was followed by the Sony RX10 IV.

Summary

So how do things add up? Which of the two cameras – the Sony RX10 III or the Panasonic FZ1000 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Panasonic Lumix DMC-FZ1000:

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has a higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Less heavy: Has a lower weight (by 220g or 21 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 III is the clear winner of the match-up (10 : 5 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.

RX10 III 10:05 FZ1000

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX10 III and the FZ1000 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
