The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon R3 was launched in the US market at a price of $5,999. 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 with a 35mm slide
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
The Canon R3 features a full frame sensor and has a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the Canon R3 among the large-sensor cameras that aim for top notch image quality.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of alternatives.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The R3 indeed provides movie recording capabilities. The highest resolution format that the R3 can use is 6K/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the R3 has an electronic viewfinder with a resolution of 5760k dots. The viewfinder offers a field of view of 100% and a magnification of 0.76x. The adjacent tables list some of the other core features of the Canon R3 along with similar information for a selection of comparators.

The LCD screen on the Canon EOS R3 is flexibly attached to the body. In particular, the LCD is hinged on the side and can be flipped out for odd-angle shots in both portrait and landscape orientation. Also, this fully articulated, swivel type of LCD attachment is often appreciated by videographers for its flexibility. Moreover, v-loggers like the design because the screen can be turned to be front-facing.
One useful feature of the R3 is a presence of a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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 Canon EOS R3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R3 has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the R3 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 adjacent table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
Canon R3 FAQ
Below are some additional questions and answers concerning some particular features of the R3.
What technology is the imaging sensor in the R3 based on?
The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Canon equipped the R3 with the DIGIC X image processor.
What is the ISO sensitivity range of the R3?
The camera has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the R3 is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the Canon EOS R3?
Canon mentions a shutter rating of 300 000 actuations for the R3. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the R3 over, say, three years, one would have to take about 300 pictures each and every day.
Is completely silent shooting possible with the Canon R3?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Canon EOS R3 has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Canon R3?
The R3 offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Canon R3 feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The R3's flash sync speed is 1/250 sec.
Does the Canon R3 support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards (data transfer speed of up to 312 MB/s).
Which battery does the R3 use?
