Canon 77D vs SX520
The Canon EOS 77D and the Canon PowerShot SX520 HS are two digital cameras that were officially introduced, respectively, in February 2017 and July 2014. The 77D is a DSLR, while the SX520 is a fixed lens compact. The cameras are based on an APS-C (77D) and a 1/2.3-inch (SX520) sensor. The 77D has a resolution of 24 megapixels, whereas the SX520 provides 15.9 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 EOS 77D and the Canon PowerShot SX520 HS? 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.
An illustration of the physical size and weight of the Canon 77D and the Canon SX520 is provided 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 size dimensions 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 SX520 is notably smaller (25 percent) than the Canon 77D. In this context, it is worth noting that neither the 77D nor the SX520 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX520 has a lens built in, whereas the 77D 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 77D and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX520 was launched at a lower price than the 77D, 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 77D features an APS-C sensor and the Canon SX520 a 1/2.3-inch sensor. The sensor area in the SX520 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the 77D has a native 3:2 aspect ratio, while the one in the SX520 offers a 4:3 aspect.
In terms of chip-set technology, the 77D uses a more advanced image processing engine (DIGIC 7) than the SX520 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the 77D offers a higher resolution than the SX520 (15.9MP), but the 77D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.33μm for the SX520) due to its larger sensor. Moreover, the 77D is a much more recent model (by 2 years and 6 months) than the SX520, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the SX520 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon 77D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 77D 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 SX520 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 77D 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 Canon PowerShot SX520 HS are ISO 100 to ISO 3200 (no boost).
In terms of underlying technology, the 77D is build around a CMOS sensor, while the SX520 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.
|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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 77D provides a higher frame rate than the SX520. It can shoot video footage at 1080/60p, while the SX520 is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 77D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX520 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 77D and Canon SX520 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 77D, but is missing on the SX520 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The 77D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX520 does not have a selfie-screen.
The Canon 77D 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 77D and the SX520 write their files to SDXC cards. The 77D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX520 cannot take advantage of Ultra High Speed SD 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 EOS 77D and Canon PowerShot SX520 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D has a hotshoe, while the SX520 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 77D and the SX520 have been discontinued, but can regularly be found used on ebay. The SX520 was replaced by the Canon SX530, while the 77D does not have a direct successor. Further information on the features and operation of the 77D and SX520 can be found, respectively, in the Canon 77D Manual (free pdf) or the online Canon SX520 Manual.
So what is the bottom line? Which of the two cameras – the Canon 77D or the Canon SX520 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- Ready to shoot: Comes with an integrated lens, while the 77D requires a separate lens.
- More compact: Is smaller (120x82mm vs 131x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 77D).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in July 2014).
If the count of individual advantages (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (27 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 77D and the Canon SX520 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 77D or the SX520 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
