Canon SX70 vs T7i
The Canon PowerShot SX70 HS and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were officially introduced, respectively, in September 2018 and February 2017. The SX70 is a fixed lens compact, while the T7i is a DSLR. The cameras are based on a 1/2.3-inch (SX70) and an APS-C (T7i) sensor. The SX70 has a resolution of 20.2 megapixels, whereas the T7i provides 24 MP.
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 PowerShot SX70 HS 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.
The physical size and weight of the Canon SX70 and the Canon T7i are illustrated 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.
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 larger (13 percent) than the Canon SX70. In this context, it is worth noting that neither the SX70 nor the T7i 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 T7i 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 T7i and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the SX70 gets 325 shots out of its LP-E12 battery, while the T7i can take 600 images on a single charge of its LP-E17 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. The SX70 was launched at a lower price than the T7i, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant 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. 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 SX70 features a 1/2.3-inch sensor and the Canon T7i an APS-C sensor. The sensor area in the T7i 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 T7i offers a 3:2 aspect.
In terms of chip-set technology, the SX70 uses a more advanced image processing engine (DIGIC 8) than the T7i (DIGIC 7), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the T7i offers a higher resolution than the SX70 (20.2MP), but the T7i 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 1 year and 7 months) than the T7i, 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 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 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 T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 T7i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
In terms of underlying technology, the SX70 is build around a BSI-CMOS sensor, while the T7i 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.
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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

|Note: DXO values in italics represent estimates based on sensor size and age.|
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 T7i. It can shoot video footage at 4K/30p, while the T7i is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX70 has an electronic viewfinder (2360k dots), while the T7i 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 following table reports on some other key feature differences and similarities of the Canon SX70, 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 SX70 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
Concerning the storage of imaging data, both the SX70 and the T7i write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 T7i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX70 does not feature such an accessory-socket.
The SX70 is a recent model that features in the current product line-up of Canon. In contrast, the T7i has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the T7i was succeeded by the Canon T8i. Further information on the features and operation of the SX70 and T7i can be found, respectively, in the Canon SX70 Manual (free pdf) or the online Canon T7i Manual.
So what is the bottom line? Is the Canon SX70 better than the Canon T7i or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor 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 7).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More framing info: Has an electronic viewfinder that displays shooting data.
- Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with a built-in lens, while the T7i requires a separate lens.
- More compact: Is smaller (127x91mm vs 131x100mm) and thus needs less room in the bag.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Is somewhat more recent (announced 1 year and 7 months after the T7i).
Reasons to prefer the Canon EOS Rebel T7i:
- 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.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- 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 (600 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 2017).
If the count of individual advantages (bullet points above) is taken as a guide, the T7i is the clear winner of the contest (16 : 10 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 T7i 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX70 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.
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], 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 above review scores should be interpreted 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
