Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX510 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

An illustration of the physical size and weight of the Canon SX510 and the Canon T7 is provided 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 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 T7 is considerably larger (79 percent) than the Canon SX510. In this context, it is worth noting that neither the SX510 nor the T7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX510 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 SX510 gets 250 shots out of its Canon NB-6LH 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX510 was launched at a lower price than the T7, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX510 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 SX510 has a native 4:3 aspect ratio, while the one in the T7 offers a 3:2 aspect.

Technology-wise, the T7 uses a more advanced image processing engine (DIGIC 4+) than the SX510 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

With 24MP, the T7 offers a higher resolution than the SX510 (15.9MP), but the T7 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.33μm for the SX510) due to its larger sensor. Moreover, the T7 is a much more recent model (by 4 years and 6 months) than the SX510, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX510 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 SX510 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 Canon PowerShot SX510 HS has a native sensitivity range from ISO 80 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the T7 provides a faster frame rate than the SX510. It can shoot movie footage at 1080/30p, while the SX510 is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the T7 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX510 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX510 and Canon T7 along with similar information for a selection of comparators.

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 SX510 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 T7 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX510 does not feature such an accessory-socket.

The T7 is a recent model that features in the current product line-up of Canon. In contrast, the SX510 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX510 was succeeded by the Canon SX520. Further information on the features and operation of the SX510 and T7 can be found, respectively, in the Canon SX510 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 SX510 and the Canon T7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot SX510 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster burst: Shoots at higher frequency (3.8 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 (104x70mm vs 129x101mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the T7).
• 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 heavily discounted: Has been available for much longer (launched in August 2013).

Arguments in favor of the Canon EOS Rebel T7:

• More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better jpgs: Has a more modern image processing engine (DIGIC 4+ vs DIGIC 4).
• Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 461k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/1600s) to freeze action.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 250) 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 modern: Reflects 4 years and 6 months of technical progress since the SX510 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the T7 is the clear winner of the contest (16 : 8 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 SX510 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 says little about, for example, the shooting experience and imaging performance of the SX510 and the T7 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.

Expert reviews

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 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.
