Sony RX10 III versus Canon 800D

The Sony Cyber-shot DSC-RX10 III and the Canon EOS 800D (labelled Canon T7i in some countries) are two digital cameras that were officially introduced, respectively, in March 2016 and February 2017. The RX10 III is a fixed lens compact, while the 800D is a DSLR. The cameras are based on an one-inch (RX10 III) and an APS-C (800D) sensor. The Sony has a resolution of 20 megapixel, whereas the Canon provides 24 MP. 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 III vs Canon 800D

The side-by-side display below illustrates the physical size and weight of the Sony RX10 III and the Canon 800D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 side – the RX10 III – represents the basis for the calculations 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 Canon 800D is somewhat larger (5 percent) than the Sony RX10 III. It is worth mentioning in this context that the RX10 III is splash and dust resistant, while the 800D does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III has a lens build in, whereas the 800D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 800D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the RX10 III gets 420 shots out of its NP-FW50 battery, while the 800D can take 600 images on a single charge of its LP-E17 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 III vs Canon 800D

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX10 III features an one-inch sensor and the Canon 800D an APS-C sensor. The sensor area in the 800D is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony RX10 III and Canon 800D sensor measures

With 24MP, the 800D offers a higher resolution than the RX10 III (20MP), but the 800D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX10 III) due to its larger sensor. Moreover, the 800D is a somewhat more recent model (by 10 months) than the RX10 III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX10 III provides a higher video resolution than the 800D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Sony RX10 III vs Canon 800D

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX10 III has an electronic viewfinder (2359k dots), while the 800D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Sony RX10 III, the Canon 800D, and comparable cameras.

  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (10 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (10 points each). 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 III 10:10 800D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX10 III and the 800D in practical situations. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
