Canon R5 vs T8i
The Canon EOS R5 and the Canon EOS Rebel T8i (labelled Canon 850D in some countries) are two digital cameras that were revealed to the public, respectively, in July 2020 and February 2020. The Canon R5 is a mirrorless interchangeable lens camera, while the T8i is a DSLR. The cameras are based on a full frame (Canon R5) and an APS-C (T8i) sensor. The Canon R5 has a resolution of 44.8 megapixels, whereas the T8i provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R5 and the Canon EOS Rebel T8i? 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.
An illustration of the physical size and weight of the Canon R5 and the Canon T8i 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 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 R5 and the Canon T8i are of equal size. However, the T8i is markedly lighter (30 percent) than the Canon R5. It is worth mentioning in this context that the Canon R5 is splash and dust resistant, while the T8i 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 Canon R5 gets 320 shots out of its LP-E6NH battery, while the T8i can take 800 images on a single charge of its LP-E17 power pack. The power pack in the Canon R5 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.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The T8i was launched at a markedly lower price (by 81 percent) than the Canon R5, 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.
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 Canon R5 features a full frame sensor and the Canon T8i an APS-C sensor. The sensor area in the T8i is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of chip-set technology, the Canon R5 uses a more advanced image processing engine (DIGIC X) than the T8i (DIGIC 8), with benefits for noise reduction, color accuracy, and processing speed.
With 44.8MP, the Canon R5 offers a higher resolution than the T8i (24MP), but the Canon R5 nevertheless has larger individual pixels (pixel pitch of 4.39μm versus 3.72μm for the T8i) due to its larger sensor. Moreover, the Canon R5 is a somewhat more recent model (by 4 months) than the T8i, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon R5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R5 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 Canon T8i are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The Canon EOS R5 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 Canon EOS Rebel T8i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Canon R5 provides a higher video resolution than the T8i. It can shoot video footage at 8k/30p, while the T8i is limited to 4K/24p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Canon R5 has an electronic viewfinder (5760k dots), while the T8i 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 R5 offers a wider field of view (100%) than the one in the T8i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Canon R5 has a higher magnification (0.76x vs 0.51x), 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 and Canon T8i in connection with corresponding information for a sample of similar cameras.

One feature that is present on the Canon R5, but is missing on the T8i 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.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 R5 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 and the Canon T8i both have 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 Canon R5 writes its imaging data to CFexpress or SDXC cards, while the T8i uses SDXC cards. The Canon R5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T8i only has one slot. The Canon R5 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the T8i can use UHS-I cards (up to 104 MB/s).
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 and Canon EOS Rebel T8i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon R5 has a headphone jack, which is not present on the T8i This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Both the Canon R5 and the T8i are recent models that are part of the current product line-up. The T8i replaced the earlier Canon T7i, while the Canon R5 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

- Less heavy: Has a lower weight (by 223g or 30 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (800 versus 320) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (81 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2020).
If the count of individual advantages (bullet points above) is taken as a guide, the Canon R5 is the clear winner of the match-up (25 : 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 R5 and the Canon T8i 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 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 Canon R5 or the T8i 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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 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.
