Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel T8i and the Sony Alpha A6700? 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 T8i and the Sony A6700. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 Sony A6700 is considerably smaller (38 percent) than the Canon T8i. Moreover, the A6700 is slightly lighter (4 percent) than the T8i. It is noteworthy in this context that the A6700 is splash and dust-proof, 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T8i) and the Sony E-Mount Lens Catalog (A6700). Mirrorless cameras, such as the A6700, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the T8i gets 800 shots out of its Canon LP-E17 battery, while the A6700 can take 570 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A6700 can be charged via the USB port, which can be very convenient when travelling.

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 T8i was launched at a markedly lower price (by 46 percent) than the A6700, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 are more costly to manufacture and tend to 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 A6700 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T8i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 25.6MP, the A6700 offers a higher resolution than the T8i (24MP), but the A6700 nevertheless has marginally larger individual pixels (pixel pitch of 3.79μm versus 3.72μm for the T8i) due to its larger sensor. Moreover, the A6700 is a much more recent model (by 3 years and 4 months) than the T8i, 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 EOS Rebel T8i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Sony Alpha A6700 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the T8i is build around a CMOS sensor, while the A6700 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 A6700 provides a faster frame rate than the T8i. It can shoot movie footage at 4K/120p, while the Canon is limited to 4K/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A6700 has an electronic viewfinder (2360k 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 A6700 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 A6700 has a higher magnification (0.71x 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 T8i, the Sony A6700, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The T8i has one, while the A6700 does not. While the built-in flash of the T8i is not very powerful, it can at times be useful as a fill-in light.

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 A6700 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 T8i and the Sony A6700 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 T8i writes its imaging data to SDXC cards, while the A6700 uses SDXC or Memory Stick PRO Duo cards. The A6700 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).

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 Rebel T8i and Sony Alpha A6700 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6700 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The T8i lacks such a headphone port.

The A6700 is a recent model that features in the current product line-up of Sony. In contrast, the T8i has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the T8i from Canon. Further information on the features and operation of the T8i and A6700 can be found, respectively, in the Canon T8i Manual (free pdf) or the online Sony A6700 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon T8i and the Sony A6700? Which camera is better? The listing below highlights the relative strengths of the two models.

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Can take more shots (800 versus 570) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2020).

Reasons to prefer the Sony Alpha A6700:

• Better video: Provides higher movie framerates (4K/120p versus 4K/24p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.51x).
• Faster burst: Shoots at higher frequency (11 vs 7.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (122x69mm vs 131x103mm) and will fit more readily into a bag.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Reflects 3 years and 4 months of technical progress since the T8i launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A6700 is the clear winner of the contest (16 : 5 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 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 T8i and the Sony A6700 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 T8i or the A6700. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
