Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 40D and the Canon EOS R? 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: Canon 40D vs Canon R
An illustration of the physical size and weight of the Canon 40D and the Canon R is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size 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 R is notably smaller (14 percent) than the Canon 40D. Moreover, the Canon R is markedly lighter (20 percent) than the 40D. It is noteworthy in this context that the Canon R is splash and dust-proof, while the 40D does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the Canon R can take 370 images on a single charge of its LP-E6N power pack. The power pack in the Canon R can be charged via the USB port, which can be very convenient when travelling.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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 40D was launched at a markedly lower price (by 43 percent) than the Canon R, which puts it into a different market segment. 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.
Sensor comparison: Canon 40D vs Canon R
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Canon R a full frame sensor. The sensor area in the Canon R is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the Canon R uses a more advanced image processing engine (DIGIC 8) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
With 30.1MP, the Canon R offers a higher resolution than the 40D (10.1MP), but the Canon R has smaller individual pixels (pixel pitch of 5.36μm versus 5.73μm for the 40D). Yet, the Canon R is a much more recent model (by 11 years) than the 40D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inch or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inch or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inch or 56.9 x 37.9 cm. The corresponding values for the Canon 40D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS R are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.
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"). Of the two cameras under consideration, the Canon R offers substantially better image quality than the 40D (overall score 25 points higher). The advantage is based on 2.4 bits higher color depth, 2.2 EV in additional dynamic range, and 2 stops in additional low light sensitivity. 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 are not only capable of taking still images, but also of capturing video footage. The Canon R indeed provides for movie recording, while the 40D does not. The highest resolution format that the Canon R can use is 4K/30p.
Feature comparison: Canon 40D vs Canon R
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Canon R has an electronic viewfinder (3690k dots), while the 40D 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 viewfinder in the Canon R offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Canon R has a higher magnification (0.76x vs 0.59x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 40D and Canon R in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the Canon R does not. While the built-in flash of the 40D is not very powerful, it can at times be useful as a fill-in light.The Canon R has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 40D does not have a selfie-screen.
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 Canon R 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 40D writes its imaging data to Compact Flash cards, while the Canon R uses SDXC cards.
Connectivity comparison: Canon 40D vs Canon R
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 40D and Canon EOS R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 40D does not offer wifi capability.
Studio photographers will appreciate that the Canon 40D (unlike the Canon R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The Canon R is a recent model that features in the current product line-up of Canon. In contrast, the 40D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the count of relative strengths (bullet points above) is taken as a measure, the Canon R is the clear winner of the contest (26 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 Canon 40D and the Canon R place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the Canon R. 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: Canon 40D vs Canon R
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
