Panasonic FZ1000 versus Sony RX10 IV

The Panasonic Lumix DMC-FZ1000 and the Sony Cyber-shot DSC-RX10 IV are two digital cameras that were announced, respectively, in June 2014 and September 2017. Both the FZ1000 and the RX10 IV are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic FZ1000 and the Sony RX10 IV. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 – the FZ1000 – represents the basis or 100 percent 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 Sony RX10 IV is somewhat smaller (8 percent) than the Panasonic FZ1000. However, the RX10 IV is markedly heavier (32 percent) than the FZ1000. It is noteworthy in this context that the RX10 IV is splash and dust-proof, while the FZ1000 does not feature any corresponding weather-sealing.

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 FZ1000 was launched at a markedly lower price (by 47 percent) than the RX10 IV, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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.

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 FZ1000 and the RX10 IV have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 IV is much more recent (by 3 years and 3 months) than the FZ1000, and its sensor will have benefitted from technological advances during this time.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The FZ1000 and the RX10 IV 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 following table reports on some other key feature differences and similarities of the Panasonic FZ1000, the Sony RX10 IV, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the FZ1000 and the RX10 IV have zoom lenses build in. The FZ1000 has a 25-400mm f/2.8-4.0 optic and the RX10 IV offers a 24-600mm f/2.4-4.0 (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 IV offers the faster maximum aperture.

The RX10 IV is a current model that online retailers, such as amazon, will have in stock. In contrast, the FZ1000 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the FZ1000 was succeeded by the Panasonic FZ2500.

Summary

So what conclusions can be drawn? Is the Panasonic FZ1000 better than the Sony RX10 IV or vice versa? The listing below highlights the relative strengths of the two models.


logo checkmark

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: Is lighter (by 264g or 24 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in June 2014).

logo checkmark

Reasons to prefer the Sony Cyber-shot DSC-RX10 IV:

  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 921k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (24 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).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (400 versus 360) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Reflects 3 years and 3 months of technical progress since the FZ1000 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 IV is the clear winner of the contest (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.

FZ1000 05:10 RX10 IV

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the FZ1000 or the RX10 IV. 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
