Canon T7 vs T8i

The Canon EOS Rebel T7 (called Canon 2000D in some regions) and the Canon EOS Rebel T8i (labelled Canon 850D in some countries) are two digital cameras that were announced, respectively, in February 2018 and February 2020. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.

As their names suggest, both the Canon EOS Rebel T7 and the Canon EOS Rebel T8i 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 T7 and Canon T8i. 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 Rebel T7 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.

Body comparison

An illustration of the physical size and weight of the Canon T7 and the Canon T8i is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

Size Canon T7 vs Canon T8i
Compare T7 versus T8i top
Comparison T7 or T8i rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T8i is somewhat larger (4 percent) than the Canon T7. Moreover, the T8i is markedly heavier (8 percent) than the T7. In this context, it is worth noting that neither the T7 nor the T8i 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 T7 gets 500 shots out of its LP-E10 battery, while the T8i can take 800 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. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 T7 was launched at a markedly lower price (by 40 percent) than the T8i, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the T8i uses a more advanced image processing engine (DIGIC 8) than the T7 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

Canon T7 and Canon T8i sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the T7 and the T8i have the same pixel density, as well as the same pixel size. It should, however, be noted that the T8i is a somewhat more recent model (by 1 year and 11 months) than the T7, and its sensor might have benefitted from technological advances during this time.

The T8i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T7 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 Rebel T8i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

T7 versus T8i MP

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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the T8i provides a better video resolution than the T7. It can shoot movie footage at 4K/24p, while the T7 is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The T7 and the T8i 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 T8i has a higher magnification than the one of the T7 (0.51x vs 0.50x), 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 T7 and Canon T8i in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T8i has a touchscreen, while the T7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The T8i 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 T7 does not have a selfie-screen.

The Canon T8i 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.

Concerning the storage of imaging data, both the T7 and the T8i write their files to SDXC cards. The T8i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T7 cannot take advantage of Ultra High Speed SD cards.

Review summary

So how do things add up? Is there a clear favorite between the Canon T7 and the Canon T8i? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS Rebel T7:

  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2018).


Advantages of the Canon EOS Rebel T8i:

  • Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 4+).
  • Better video: Provides higher definition movie capture (4K/24p vs 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.50x).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k 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 (7.5 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (800 versus 500) out of a single battery charge.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the T8i is the clear winner of the contest (15 : 3 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

T7 03:15 T8i

How about other alternatives? Do the specifications of the Canon T7 and the Canon T8i 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T7 or the T8i. 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 hands-on reviews by experts 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], 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.

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

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
