Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Digital Rebel and the Nikon D850? 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 Rebel and the Nikon D850 is provided in the side-by-side display below. 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 Nikon D850 is notably larger (29 percent) than the Canon Rebel. Moreover, the D850 is substantially heavier (55 percent) than the Rebel. It is noteworthy in this context that the D850 is splash and dust-proof, while the Rebel 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (Rebel) and the Nikon Lens Catalog (D850).

Concerning battery life, the Rebel gets 400 shots out of its Canon BP-511 battery, while the D850 can take 1840 images on a single charge of its Nikon EN-EL15a power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The Rebel was launched at a markedly lower price (by 73 percent) than the D850, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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.

Of the two cameras under consideration, the Canon Rebel features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 150 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.

With 45.4MP, the D850 offers a higher resolution than the Rebel (6.3MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 7.38μm for the Rebel). Yet, the D850 is a much more recent model (by 13 years and 11 months) than the Rebel, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Canon Rebel are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.

The Canon EOS Digital Rebel has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.

In terms of underlying technology, the Rebel is build around a CMOS sensor, while the D850 uses a BSI-CMOS 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"). Of the two cameras under consideration, the D850 offers substantially better image quality than the Rebel (overall score 45 points higher). The advantage is based on 5.4 bits higher color depth, 4 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 D850 indeed provides for movie recording, while the Rebel does not. The highest resolution format that the D850 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The Rebel and the D850 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the D850 offers a wider field of view (100%) than the one in the Rebel (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D850 has a higher magnification (0.75x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon Rebel, the Nikon D850, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The Rebel has one, while the D850 does not. While the built-in flash of the Rebel is not very powerful, it can at times be useful as a fill-in light.

The Nikon D850 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 Rebel writes its imaging data to Compact Flash cards, while the D850 uses SDXC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Rebel only has one slot.

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 Digital Rebel and Nikon D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D850 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Rebel does not provide wifi capability.

Studio photographers will appreciate that the Nikon D850 (unlike the Rebel) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the Rebel has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the Rebel was succeeded by the Canon XT. Further information on the features and operation of the Rebel and D850 can be found, respectively, in the Canon Rebel Manual (free pdf) or the online Nikon D850 Manual.

Review summary

So what is the bottom line? Is the Canon Rebel better than the Nikon D850 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS Digital Rebel:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

• More modern: Reflects 13 years and 11 months of technical progress since the Rebel launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D850 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Rebel and the Nikon D850 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 Rebel or the D850. 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 expert reviews 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
