Sony RX10 versus Sony RX10 IV

The Sony Cyber-shot DSC-RX10 and the Sony Cyber-shot DSC-RX10 IV are two enthusiast cameras that were officially introduced, respectively, in October 2013 and September 2017. Both the RX10 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. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony RX10 vs Sony RX10 IV

An illustration of the physical size and weight of the Sony RX10 and the Sony RX10 IV is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 – represents 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 notably larger (10 percent) than the Sony RX10. Moreover, the RX10 IV is substantially heavier (35 percent) than the RX10. 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 camera comparisons there.

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 RX10 was launched at a somewhat lower price (by 24 percent) than the RX10 IV, which makes it more attractive for photographers on a tight budget. 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: Sony RX10 vs Sony RX10 IV

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to 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 RX10 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 10 months) than the RX10, 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX10 IV provides a better video resolution than the RX10. It can shoot movie footage at 4K/30p, while the RX10 is limited to 1080/60p.

Feature comparison: Sony RX10 vs Sony RX10 IV

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 RX10 IV offers a substantially higher resolution than the one in the RX10 (2359k vs 1440k dots). The table below summarizes some of the other core capabilities of the Sony RX10 and Sony RX10 IV in connection with corresponding information for a sample of similar cameras.

Both the RX10 and the RX10 IV have zoom lenses build in. The RX10 has a 24-200mm f/2.8-2.8 optic and the RX10 IV offers a 24-600mm f/2.4-4.0 (focal lengths in full frame equivalent terms). Hence, the RX10 and RX10 IV provide the same view at the wide-angle end, but the RX10 IV has more tele-photo reach at the long end. 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 RX10 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX10 was succeeded by the Sony RX10 II.

Review summary: Sony RX10 vs Sony RX10 IV

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


Advantages of the Sony Cyber-shot DSC-RX10:

  • Faster shutter: Has higher mechanical shutter speed (3200/sec vs 2000/sec) to freeze action.
  • Less heavy: Is lighter (by 282g or 26 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in October 2013).

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

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1229k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (24 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/2.8).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More modern: Reflects 3 years and 10 months of technical progress since the RX10 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 IV is the clear winner of the contest (8 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

RX10 04:08 RX10 IV

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the RX10 or the RX10 IV handle or perform in practice. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
