Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX720 HS and the Sony Alpha A3000? 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 Sony A3000 is provided in the side-by-side display below. 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.

The SX720 can be obtained in two different colors (black, red), while the A3000 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 Sony A3000 is considerably larger (65 percent) than the Canon SX720. In this context, it is worth noting that neither the SX720 nor the A3000 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 A3000 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 A3000 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the SX720 gets 250 shots out of its Canon NB-13L battery, while the A3000 can take 470 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 SX720 features a 1/2.3-inch sensor and the Sony A3000 an APS-C sensor. The sensor area in the A3000 is 1175 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 A3000 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX720 offers a higher resolution of 20.2 megapixels, compared with 19.8 MP of the Sony A3000. 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 4.25μm for the A3000). However, it should be noted that the SX720 is much more recent (by 2 years and 5 months) than the A3000, 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 Canon PowerShot SX720 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Sony Alpha A3000 are ISO 100 to ISO 16000 (no boost).

In terms of underlying technology, the SX720 is build around a BSI-CMOS sensor, while the A3000 uses a 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the SX720 provides a higher frame rate than the A3000. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A3000 has an electronic viewfinder (202k dots), which can be very helpful 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 Sony A3000 in connection with corresponding information for a sample of similar cameras.

It is notable that the SX720 offers wifi support, while the A3000 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the SX720 and the A3000 have been discontinued, but can regularly be found used on ebay. The SX720 was replaced by the Canon SX730, while the A3000 does not have a direct successor. Further information on the features and operation of the SX720 and A3000 can be found, respectively, in the Canon SX720 Manual (free pdf) or the online Sony A3000 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon SX720 or the Sony A3000 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot SX720 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Faster burst: Shoots at higher frequency (5.9 vs 2.5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the A3000 requires a separate lens.
• More compact: Is smaller (110x64mm vs 128x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the A3000).
• 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 modern: Reflects 2 years and 5 months of technical progress since the A3000 launch.

Advantages of the Sony Alpha A3000:

• 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 electronic viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (470 versus 250) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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 August 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (12 points each). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Sony A3000 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX720 and the A3000 in practical situations. 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted 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, please note that some of the review sites have changed their methodology and reporting over time.
