Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX70 HS and the Canon EOS Rebel T7? 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 physical size and weight of the Canon SX70 and the Canon T7 are illustrated in the side-by-side display below. 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 Canon T7 is notably larger (13 percent) than the Canon SX70. In this context, it is worth noting that neither the SX70 nor the T7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX70 has a lens built in, whereas the T7 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the T7 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the SX70 gets 325 shots out of its Canon LP-E12 battery, while the T7 can take 500 images on a single charge of its Canon LP-E10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon SX70 features a 1/2.3-inch sensor and the Canon T7 an APS-C sensor. The sensor area in the T7 is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX70 has a native 4:3 aspect ratio, while the one in the T7 offers a 3:2 aspect.

In terms of chip-set technology, the SX70 uses a more advanced image processing engine (DIGIC 8) than the T7 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

With 24MP, the T7 offers a higher resolution than the SX70 (20.2MP), but the T7 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.18μm for the SX70) due to its larger sensor. However, the SX70 is a somewhat more recent model (by 6 months) than the T7, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon T7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7 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 SX70 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The Canon PowerShot SX70 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel T7 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the SX70 is build around a BSI-CMOS sensor, while the T7 uses a 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 SX70 provides a higher video resolution than the T7. It can shoot video footage at 4K/30p, while the T7 is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SX70 has an electronic viewfinder (2360k dots), while the T7 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 adjacent table lists some of the other core features of the Canon SX70 and Canon T7 along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the SX70 and the T7 write their files to SDXC cards. The SX70 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.

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 PowerShot SX70 HS and Canon EOS Rebel T7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX70 has a microphone port, which is missing on the T7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the SX70 and the T7 are recent models that are part of the current product line-up. The T7 replaced the earlier Canon T6, while the SX70 followed on from the Canon SX60 . Further information on the features and operation of the SX70 and T7 can be found, respectively, in the Canon SX70 Manual (free pdf) or the online Canon T7 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX70 and the Canon T7? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX70 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 4+).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with a built-in lens, while the T7 requires a separate lens.
• More compact: Is smaller (127x91mm vs 129x101mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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: Is somewhat more recent (announced 6 months after the T7).

Arguments in favor of the Canon EOS Rebel T7:

• More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 325) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been on the market for longer (launched in February 2018).

If the number of relative strengths (bullet points above) is taken as a guide, the SX70 comes out slightly ahead of the T7 (14 : 13 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 SX70 and the Canon T7 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings 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 SX70 or the T7. 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.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
