Canon SX620 vs T3i
The Canon PowerShot SX620 HS and the Canon EOS Rebel T3i (labelled Canon 600D in some countries) are two digital cameras that were officially introduced, respectively, in May 2016 and February 2011. The SX620 is a fixed lens compact, while the T3i is a DSLR. The cameras are based on a 1/2.3-inch (SX620) and an APS-C (T3i) sensor. The SX620 has a resolution of 20.2 megapixels, whereas the T3i provides 17.9 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 SX620 HS and the Canon EOS Rebel T3i? 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 SX620 and the Canon T3i are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The SX620 can be obtained in three different colors (black, silver, red), while the T3i is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T3i is considerably larger (141 percent) than the Canon SX620. In this context, it is worth noting that neither the SX620 nor the T3i are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 has a lens built in, whereas the T3i 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 T3i and their specifications in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

Any camera decision will naturally be influenced heavily by the price. 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 SX620 was launched at a lower price than the T3i, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.
Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Canon T3i an APS-C sensor. The sensor area in the T3i 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 SX620 has a native 4:3 aspect ratio, while the one in the T3i offers a 3:2 aspect.
In terms of chip-set technology, the SX620 uses a more advanced image processing engine (DIGIC 4+) than the T3i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the Canon SX620 offers a higher resolution of 20.2 megapixels, compared with 17.9 MP of the Canon T3i. 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 1.18μm versus 4.31μm for the T3i). However, it should be noted that the SX620 is much more recent (by 5 years and 3 months) than the T3i, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX620 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel T3i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Canon G9 X Mark II||1-inch||20.0||5472||3648||1080/60p||21.9||12.5||522||65|

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T3i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX620 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX620, the Canon T3i, and comparable cameras.

Concerning the storage of imaging data, both the SX620 and the T3i write their files to SDXC cards.
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 SX620 HS and Canon EOS Rebel T3i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX620 offers wifi support, while the T3i does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The SX620 is a recent model that features in the current product line-up of Canon. In contrast, the T3i has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the T3i was succeeded by the Canon T4i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Is the Canon SX620 better than the Canon T3i or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot SX620 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 4+ vs DIGIC 4).
- Ready to shoot: Comes with a built-in lens, while the T3i requires a separate lens.
- More compact: Is smaller (97x57mm vs 133x100mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the T3i).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- 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.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 5 years and 3 months of technical progress since the T3i launch.
Advantages of the Canon EOS Rebel T3i:
- 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 sound: Can connect to an external microphone for higher quality sound recording.

- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (3.7 vs 2.5 flaps/sec) to capture the decisive moment.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (440 versus 295) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in February 2011).
If the number of relative strengths (bullet points above) is taken as a guide, the T3i is the clear winner of the contest (16 : 10 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 SX620 and the Canon T3i 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 incomplete and does no justice, for example, to the way the SX620 or the T3i perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
