Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX720 HS and the Nikon D3000? 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 SX720 and the Nikon D3000 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.

The SX720 can be obtained in two different colors (black, red), while the D3000 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 Nikon D3000 is considerably larger (74 percent) than the Canon SX720. In this context, it is worth noting that neither the SX720 nor the D3000 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX720 has a lens built in, whereas the D3000 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 D3000 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the SX720 gets 250 shots out of its Canon NB-13L battery, while the D3000 can take 500 images on a single charge of its Nikon EN-EL9a power pack.

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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 SX720 was launched at a lower price than the D3000, 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.

Sensor comparison

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX720 features a 1/2.3-inch sensor and the Nikon D3000 an APS-C sensor. The sensor area in the D3000 is 1232 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 SX720 has a native 4:3 aspect ratio, while the one in the D3000 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX720 offers a higher resolution of 20.2 megapixels, compared with 10 MP of the Nikon D3000. 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 6.11μm for the D3000). However, it should be noted that the SX720 is much more recent (by 6 years and 6 months) than the D3000, 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 SX720 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX720 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX720 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D3000 are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.

The Canon PowerShot SX720 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Nikon D3000 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the SX720 is build around a BSI-CMOS sensor, while the D3000 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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The SX720 indeed provides movie recording capabilities, while the D3000 does not. The highest resolution format that the SX720 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D3000 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX720 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX720 and Nikon D3000 in connection with corresponding information for a sample of similar cameras.

The SX720 writes its imaging data to SDXC cards, while the D3000 uses SDHC cards. The SX720 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3000 cannot take advantage of Ultra High Speed SD 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 SX720 HS and Nikon D3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX720 offers wifi support, while the D3000 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the SX720 and the D3000 have been discontinued, but can regularly be found used on ebay. The D3000 was replaced by the Nikon D3100, while the SX720 was followed by the Canon SX730. Further information on the features and operation of the SX720 and D3000 can be found, respectively, in the Canon SX720 Manual (free pdf) or the online Nikon D3000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX720 and the Nikon D3000? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon PowerShot SX720 HS:

• More detail: Offers more megapixels (20.2 vs 10MP) with a 39% 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 1080/60p movies.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Faster burst: Shoots at higher frequency (5.9 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with a built-in lens, while the D3000 requires a separate lens.
• More compact: Is smaller (110x64mm vs 126x97mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D3000).
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 6 years and 6 months of technical progress since the D3000 launch.

Reasons to prefer the Nikon D3000:

• 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 1/3200s) 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.
• More heavily discounted: Has been around for much longer (launched in July 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the SX720 emerges as the winner of the contest (14 : 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 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 SX720 and the Nikon D3000 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 SX720 and the D3000 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 where reviews by experts come in. 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
