Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX10 III and the Canon EOS-1D? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX10 III and the Canon 1D. The two cameras are presented according to their relative size. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D is considerably larger (97 percent) than the Sony RX10 III. 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 above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III has a lens built in, whereas the 1D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 1D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the RX10 III gets 420 shots out of its Sony NP-FW50 battery, while the 1D can take 500 images on a single charge of its Canon NP-E3 power pack. As can be seen in the images above, the 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the RX10 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 III was launched at a lower price than the 1D, despite having a lens built in. 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.

Sensor comparison

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. 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 tend to be more expensive and 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 1D an APS-H sensor. The sensor area in the 1D is 372 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Sony RX10 III offers a higher resolution of 20 megapixels, compared with 4.1 MP of the Canon 1D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 11.56μm for the 1D). However, it should be noted that the RX10 III is much more recent (by 14 years and 6 months) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Sony RX10 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 cm for excellent quality prints.

The Sony Cyber-shot DSC-RX10 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The corresponding ISO settings for the Canon EOS-1D are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the RX10 III is build around a BSI-CMOS sensor, while the 1D uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The RX10 III indeed provides movie recording capabilities, while the 1D does not. The highest resolution format that the RX10 III can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX10 III has an electronic viewfinder (2359k dots), while the 1D 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the RX10 III has a higher magnification than the one of the 1D (0.70x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Sony RX10 III and Canon 1D along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The RX10 III has one, while the 1D does not. While the built-in flash of the RX10 III is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX10 III is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The RX10 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 1D uses Compact Flash cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Cyber-shot DSC-RX10 III and Canon EOS-1D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 III offers wifi support, while the 1D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Canon 1D (unlike the RX10 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the RX10 III and the 1D have been discontinued, but can regularly be found used on ebay. The 1D was replaced by the Canon 1D Mark II, while the RX10 III was followed by the Sony RX10 IV. Further information on the features and operation of the RX10 III and 1D can be found, respectively, in the Sony RX10 III Manual (free pdf) or the online Canon 1D Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony RX10 III and the Canon 1D? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Cyber-shot DSC-RX10 III:

• More detail: Offers more megapixels (20 vs 4.1MP) with a 119% higher linear resolution.
• Broader imaging potential: Can record not only still images but also 4K/30p movies.
• More framing info: Has an electronic viewfinder that displays shooting data.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 III is the clear winner of the match-up (19 : 7 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony RX10 III and the Canon 1D place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the RX10 III and the 1D in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
