Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R5 Mark II and the Nikon D40? 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
An illustration of the physical size and weight of the Canon R5 Mark II and the Nikon D40 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Nikon D40 is notably smaller (14 percent) than the Canon R5 Mark II. Moreover, the D40 is markedly lighter (30 percent) than the R5 Mark II. It is worth mentioning in this context that the R5 Mark II is splash and dust resistant, while the D40 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.
The power pack in the R5 Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40 was launched at a markedly lower price (by 88 percent) than the R5 Mark II, 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.
Sensor comparison
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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon R5 Mark II features a full frame sensor and the Nikon D40 an APS-C sensor. The sensor area in the D40 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 44.8MP, the R5 Mark II offers a higher resolution than the D40 (6MP), but the R5 Mark II has smaller individual pixels (pixel pitch of 4.39μm versus 7.85μm for the D40). However, the R5 Mark II is a much more recent model (by 17 years and 8 months) than the D40, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon R5 Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R5 Mark II for good quality output (200 dots per inch) amounts to 41 x 27.3 inches or 104 x 69.4 cm, for very good quality (250 dpi) 32.8 x 21.9 inches or 83.2 x 55.5 cm, and for excellent quality (300 dpi) 27.3 x 18.2 inches or 69.4 x 46.3 cm. The corresponding values for the Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The R5 Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS R5 Mark II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-102400. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.
In terms of underlying technology, the R5 Mark II is build around a CMOS sensor, while the D40 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.

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").

Many modern cameras cannot only take still pictures, but also record videos. The R5 Mark II indeed provides movie recording capabilities, while the D40 does not. The highest resolution format that the R5 Mark II can use is 8k/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the R5 Mark II has an electronic viewfinder (5760k dots), while the D40 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 R5 Mark II offers a wider field of view (100%) than the one in the D40 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the R5 Mark II has a higher magnification (0.76x vs 0.53x), 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 R5 Mark II and Nikon D40 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the R5 Mark II, but is missing on the D40 is 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.
The R5 Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D40 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 R5 Mark II 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 Canon R5 Mark II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The R5 Mark II writes its imaging data to CFexpress (type B) or SDXC cards, while the D40 uses SDHC cards. The R5 Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40 only has one slot. The R5 Mark II supports UHS-II cards (on both slots), while the D40 cannot take advantage of Ultra High Speed SD 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 Canon EOS R5 Mark II and Nikon D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R5 Mark II offers wifi support, while the D40 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 R5 Mark II (unlike the D40) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The R5 Mark II is a recent model that features in the current product line-up of Canon. In contrast, the D40 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D40 was succeeded by the Nikon D40X. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

If the count of individual advantages (bullet points above) is taken as a guide, the R5 Mark II is the clear winner of the match-up (31 : 7 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 before making a decision 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 Canon R5 Mark II and the Nikon D40 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the R5 Mark II or the D40 perform in practice. 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.
Expert reviews
This is why expert reviews are important. The adjacent summary-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]). 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 review scores listed above should be treated 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
