Sony RX10 III versus Sony RX100 IV
The Sony Cyber-shot DSC-RX10 III and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were revealed to the public, respectively, in March 2016 and June 2015. Both the RX10 III 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.
An illustration of the physical size and weight of the Sony RX10 III and the Sony RX100 IV is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 III – 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 RX100 IV is considerably smaller (53 percent) than the Sony RX10 III. Moreover, the RX100 IV is substantially lighter (72 percent) than the RX10 III. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. It is worth mentioning in this context that the RX10 III is splash and dust resistant, while the RX100 IV 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 RX100 IV was launched at a markedly lower price (by 33 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. 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. 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 tent 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.
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 RX100 IV 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 9 months) than the RX100 IV, 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 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).
Apart from body and sensor, cameras can and do differ across a variety of features. The RX10 III 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). The table below summarizes some of the other core capabilities of the Sony RX10 III and Sony RX100 IV in connection with corresponding information for a sample of similar cameras. 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 RX100 IV have zoom lenses build in. The RX10 III 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 III 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.
Both the RX10 III and the RX100 IV have been discontinued, but can regularly be found used on ebay. The RX100 IV was replaced by the Sony RX100 V, while the RX10 III was followed by the Sony RX10 IV.
So how do things add up? Is there a clear favorite between the Sony RX10 III and the Sony RX10 III? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Sony Cyber-shot DSC-RX10 III:
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Longer lasting: Can take more shots (420 versus 280) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More modern: Is somewhat more recent (announced 9 months after the RX100 IV).
Arguments in favor of the Sony Cyber-shot DSC-RX100 IV:
- Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.4).
- More compact: Is smaller (102x58mm vs 133x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 753g or 72 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- 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 RX100 IV emerges as the winner of the match-up (6 : 4 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 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 RX10 III or the RX100 IV. 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 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 above review scores should be interpreted with care, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
