Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX610 HS and the Olympus Tough TG-6? 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 SX610 and the Olympus TG-6. 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.

The SX610 can be obtained in three different colors (black, red, white), while the TG-6 is available in two color-versions (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus TG-6 is notably larger (16 percent) than the Canon SX610. Moreover, the TG-6 is markedly heavier (32 percent) than the SX610. It is noteworthy in this context that the TG-6 is splash and dust-proof, while the SX610 does not feature any corresponding weather-sealing. More than that, the TG-6 is water-proof up to 15m and can, thus, be used for underwater photography.

Concerning battery life, the SX610 gets 270 shots out of its Canon NB-6LH battery, while the TG-6 can take 340 images on a single charge of its Olympus LI-92B power pack. The power pack in the TG-6 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 45 percent) than the TG-6, 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the SX610 offers a higher resolution of 20.2 megapixels, compared with 12 MP of the TG-6. This megapixels advantage translates into a 30 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX610 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.53μm for the TG-6). Moreover, it should be noted that the TG-6 is much more recent (by 4 years and 4 months) than the SX610, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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 Olympus TG-6 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 SX610 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Olympus Tough TG-6 are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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.

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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the TG-6 provides a better video resolution than the SX610. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The SX610 and the TG-6 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Canon SX610 and Olympus TG-6 along with similar information for a selection of comparators.

The Olympus TG-6 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both the SX610 and the TG-6 have zoom lenses built in. The SX610 has a 25-450mm f/3.8-6.9 optic and the TG-6 offers a 25-100mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the Canon and Olympus provide the same view at the wide-angle end, but the Olympus has less tele-photo reach at the long end. The TG-6 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX610 and the TG-6 write their files to SDXC cards. The TG-6 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX610 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 SX610 HS and Olympus Tough TG-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Travel and landscape photographers will find it useful that the TG-6 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the SX610 and the TG-6 have been discontinued, but can regularly be found used on ebay. The SX610 was replaced by the Canon SX620, while the TG-6 was followed by the OM System TG-7. Further information on the features and operation of the SX610 and TG-6 can be found, respectively, in the Canon SX610 Manual (free pdf) or the online Olympus TG-6 Manual.

Review summary

So what is the bottom line? Is the Canon SX610 better than the Olympus TG-6 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX610 HS:

• More detail: Offers more megapixels (20.2 vs 12MP) with a 30% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (105x61mm vs 113x66mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 62g or 25 percent) and hence easier to carry around.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in January 2015).

Arguments in favor of the Olympus Tough TG-6:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Faster burst: Shoots at higher frequency (20 vs 2.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/3.8).
• Longer lasting: Gets more shots (340 versus 270) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 15m).
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 4 months of technical progress since the SX610 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TG-6 is the clear winner of the contest (13 : 8 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 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 SX610 and the Olympus TG-6 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom 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 SX610 and the TG-6 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 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
