Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 and the Canon PowerShot SX610 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.

Body comparison

The physical size and weight of the Canon G15 and the Canon SX610 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

The SX610 can be obtained in three different colors (black, red, white), while the G15 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 Canon SX610 is notably smaller (21 percent) than the Canon G15. Moreover, the SX610 is substantially lighter (46 percent) than the G15. In this context, it is worth noting that neither the G15 nor the SX610 are weather-sealed.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the SX610 can take 270 images on a single charge of its Canon NB-6LH power pack.

The price is, of course, an important factor in any camera decision. 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 SX610 was launched at a markedly lower price (by 50 percent) than the G15, which puts it into a different market segment. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 G15 features a 1/1.7-inch sensor and the Canon SX610 a 1/2.3-inch sensor. The sensor area in the SX610 is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of chip-set technology, the G15 uses a more advanced image processing engine (DIGIC 5) than the SX610 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the SX610 offers a higher resolution of 20.2 megapixels, compared with 12 MP of the G15. 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 1.89μm for the G15). However, it should be noted that the SX610 is much more recent (by 2 years and 3 months) than the G15, 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 SX610 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX610 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX610 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 Canon G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX610 HS are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the G15 is build around a CMOS sensor, while the SX610 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX610 provides a faster frame rate than the G15. It can shoot movie footage at 1080/30p, while the G15 is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G15 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX610 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G15, the Canon SX610, and comparable cameras.

Both the G15 and the SX610 have zoom lenses built in. The G15 has a 28-140mm f/1.8-2.8 optic and the SX610 offers a 25-450mm f/3.8-6.9 (focal lengths in full frame equivalent terms). Hence, the SX610 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G15. The G15 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G15 and the SX610 write their files to SDXC 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 G15 and Canon PowerShot SX610 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G15 has a hotshoe, while the SX610 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G15 and the SX610 have been discontinued, but can regularly be found used on ebay. The G15 was replaced by the Canon G16, while the SX610 was followed by the Canon SX620. Further information on the features and operation of the G15 and SX610 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Canon SX610 Manual.

Review summary

So what is the bottom line? Is the Canon G15 better than the Canon SX610 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot G15:

• 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.
• Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 4+).
• 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.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.8).
• Longer lasting: Can take more shots (350 versus 270) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in September 2012).

Reasons to prefer the Canon PowerShot SX610 HS:

• More detail: Has more megapixels (20.2 vs 12MP), which boosts linear resolution by 30%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
• Faster burst: Shoots at higher frequency (2.5 vs 2.1 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (105x61mm vs 107x76mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 161g or 46 percent) and is thus easier to take along.
• 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.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More modern: Reflects 2 years and 3 months of technical progress since the G15 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (12 points each). 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 G15 and the Canon SX610 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 G15 or the SX610 perform in practice. 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 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
