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 larger (8 percent) than the Canon T2i. Moreover, the Canon R is markedly heavier (25 percent) than the T2i. It is noteworthy in this context that the Canon R is splash and dust-proof, while the T2i 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 T2i gets 440 shots out of its LP-E8 battery, while the Canon R can take 370 images on a single charge of its LP-E6N power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T2i was launched at a markedly lower price (by 70 percent) than the Canon R, 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: Canon T2i vs Canon R

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T2i 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 T2i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

Canon T2i and Canon R sensor measures

With 30.1MP, the Canon R offers a higher resolution than the T2i (17.9MP), but the Canon R nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 4.31μm for the T2i) due to its larger sensor. Moreover, the Canon R is a much more recent model (by 8 years and 6 months) than the T2i, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS Rebel T2i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. 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..

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Canon R provides a better video resolution than the T2i. It can shoot movie footage at 4K/30p, while the T2i is limited to 1080/30p.

 

Feature comparison: Canon T2i 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 T2i 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.

One difference between the cameras concerns the presence of an on-board flash. The T2i has one, while the Canon R does not. While the built-in flash of the T2i 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 T2i does not have a selfie-screen.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the Canon R features an 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).

Concerning the storage of imaging data, both the T2i and the Canon R write their files to SDXC cards.

Connectivity comparison: Canon T2i 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 Rebel T2i and Canon EOS R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

T2i 06:23 Canon R

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the T2i or the Canon R. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
