Sony RX10 IV versus Sony RX100 IV

The Sony Cyber-shot DSC-RX10 IV and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were revealed to the public, respectively, in September 2017 and June 2015. Both the RX10 IV and the RX100 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 IV vs Sony RX100 IV

The physical size and weight of the Sony RX10 IV and the Sony RX100 IV 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. 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 RX10 IV – represents 100 percent across all the size and weight measures).

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 RX100 IV was launched at a markedly lower price (by 41 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: Sony RX10 IV vs Sony RX100 IV

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. 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.

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.

Sony RX10 IV and Sony RX100 IV sensor measures

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 IV and the RX100 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 2 years and 3 months) than the RX100 IV, and its sensor will have benefitted from technological advances during this time.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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: Sony RX10 IV vs Sony RX100 IV

Apart from body and sensor, cameras can and do differ across a variety of features. The RX10 IV and the RX100 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.

Both the RX10 IV and the RX100 IV have zoom lenses build in. The RX10 IV has a 24-600mm f/2.4-4.0 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the RX10 IV and RX100 IV provide the same view at the wide-angle end, but the RX100 IV has less tele-photo reach at the long end. The RX100 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 RX100 IV has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 IV.

Review summary: Sony RX10 IV vs Sony RX100 IV

So what conclusions can be drawn? Is there a clear favorite between the Sony RX10 IV and the Sony RX100 IV? The listing below highlights the relative strengths of the two models.


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

  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1228k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (24 vs 16 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Can take more shots (400 versus 280) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Reflects 2 years and 3 months of technical progress since the RX100 IV launch.


Arguments in favor of the Sony Cyber-shot DSC-RX100 IV:

  • More compact: Is smaller (102x58mm vs 133x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 797g or 73 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (41 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in June 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV emerges as the winner of the contest (8 : 5 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 IV 08:05 RX100 IV

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 IV or the RX100 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
