Canon Rebel vs T7i

The Canon EOS Digital Rebel (called Canon 300D in some regions) and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were officially introduced, respectively, in August 2003 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Rebel has a resolution of 6.3 megapixels, whereas the T7i provides 24 MP.

As their names suggest, both the Canon EOS Digital Rebel and the Canon EOS Rebel T7i belong to Canon's Rebel line of DSLR cameras. This range of APS-C cameras, which started out with the Canon EOS Digital Rebel in 2003, has been a big commercial success and the backbone of Canon's dominance in the digital camera market. The popularity of the Rebel cameras is the result of them inheriting much of the sensor and shooting technology from earlier released professional DSLRs, while being sold at a much more budget-friendly price point. The strong brand reputation of Canon and the comprehensive EOS system of compatible lenses and accessories further contributes to the appeal of the Rebel cams, including the Canon Rebel and Canon T7i. 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 Digital Rebel and the Canon EOS Rebel T7i? 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

The side-by-side display below illustrates the physical size and weight of the Canon Rebel and the Canon T7i. 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 width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon Rebel vs Canon T7i
Compare Rebel versus T7i top
Comparison Rebel or T7i rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T7i is notably smaller (7 percent) than the Canon Rebel. Moreover, the T7i is markedly lighter (18 percent) than the Rebel. In this context, it is worth noting that neither the Rebel nor the T7i are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the Rebel gets 400 shots out of its BP-511 battery, while the T7i can take 600 images on a single charge of its LP-E17 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 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 T7i was launched at a somewhat lower price (by 17 percent) than the Rebel, which makes it more attractive for photographers on a tight budget. 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the T7i is 3 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon Rebel and Canon T7i sensor measures

Despite having a slightly smaller sensor, the T7i offers a higher resolution of 24 megapixels, compared with 6.3 MP of the Rebel. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 7.38μm for the Rebel). However, it should be noted that the T7i is much more recent (by 13 years and 6 months) than the Rebel, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Digital Rebel has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS Rebel T7i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The Rebel and the T7i 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the Rebel has a higher magnification than the one of the T7i (0.55x vs 0.51x), 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 Canon T7i, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T7i has a touchscreen, while the Rebel has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The T7i 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 Rebel does not have a selfie-screen.

The Rebel writes its imaging data to Compact Flash cards, while the T7i uses SDXC cards.

Review summary

So how do things add up? Which of the two cameras – the Canon Rebel or the Canon T7i – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS Digital Rebel:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.51x).
  • More heavily discounted: Has been available for much longer (launched in August 2003).


Arguments in favor of the Canon EOS Rebel T7i:

  • More detail: Has more megapixels (24 vs 6.3MP), which boosts linear resolution by 95%.
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (6 vs 2.5 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 117g or 18 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (600 versus 400) out of a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
  • More modern: Reflects 13 years and 6 months of technical progress since the Rebel launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T7i is the clear winner of the contest (17 : 2 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.

Rebel 02:17 T7i

How about other alternatives? Do the specifications of the Canon Rebel and the Canon T7i 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 says little about, for example, the shooting experience and imaging performance of the Rebel and the T7i in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
