Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX520 HS and the Nikon D40? 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 side-by-side display below illustrates the physical size and weight of the Canon SX520 and the Nikon D40. 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 Nikon D40 is notably larger (18 percent) than the Canon SX520. In this context, it is worth noting that neither the SX520 nor the D40 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 D40 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 D40 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the SX520 gets 210 shots out of its Canon NB-6LH battery, while the D40 can take 470 images on a single charge of its Nikon EN-EL9 power pack.

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

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 SX520 was launched at a lower price than the D40, 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.

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 SX520 features a 1/2.3-inch sensor and the Nikon D40 an APS-C sensor. The sensor area in the D40 is 1221 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX520 has a native 4:3 aspect ratio, while the one in the D40 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX520 offers a higher resolution of 15.9 megapixels, compared with 6 MP of the Nikon D40. 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 1.33μm versus 7.85μm for the D40). However, it should be noted that the SX520 is much more recent (by 7 years and 8 months) than the D40, 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 SX520 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX520 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX520 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Canon PowerShot SX520 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.

In terms of underlying technology, the SX520 is build around a BSI-CMOS sensor, while the D40 uses a CCD 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 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The SX520 indeed provides movie recording capabilities, while the D40 does not. The highest resolution format that the SX520 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40 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 SX520 and Nikon D40 in connection with corresponding information for a sample of similar cameras.

The SX520 writes its imaging data to SDXC cards, while the D40 uses SDHC 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 SX520 HS and Nikon D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D40 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX520 does not feature such an accessory-socket.

Both the SX520 and the D40 have been discontinued, but can regularly be found used on ebay. The D40 was replaced by the Nikon D40X, while the SX520 was followed by the Canon SX530. Further information on the features and operation of the SX520 and D40 can be found, respectively, in the Canon SX520 Manual (free pdf) or the online Nikon D40 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX520 better than the Nikon D40 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon PowerShot SX520 HS:

• More detail: Offers more megapixels (15.9 vs 6MP) with a 59% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• Ready to shoot: Comes with a built-in lens, while the D40 requires a separate lens.
• More compact: Is smaller (120x82mm vs 124x94mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D40).
• 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: Reflects 7 years and 8 months of technical progress since the D40 launch.

Advantages of the Nikon D40:

• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (2.5 vs 1.6 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 (470 versus 210) 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 November 2006).

If the count of individual advantages (bullet points above) is taken as a guide, the D40 comes out slightly ahead of the SX520 (12 : 11 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 SX520 and the Nikon D40 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the SX520 and the D40 in practical situations. 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.

Expert reviews

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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
