Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX620 HS and the Ricoh GR? 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 SX620 and the Ricoh GR. 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 dimensions are rounded to the nearest millimeter.

The SX620 can be obtained in three different colors (black, silver, red), while the GR is only available in black.

Comparison SX620 or GR rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR is notably larger (29 percent) than the Canon SX620. Moreover, the GR is substantially heavier (35 percent) than the SX620. In this context, it is worth noting that neither the SX620 nor the GR are weather-sealed.

Concerning battery life, the SX620 gets 295 shots out of its NB-13L battery, while the GR can take 290 images on a single charge of its DB65 power pack. The power pack in the GR 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX620 was launched at a markedly lower price (by 65 percent) than the GR, which puts it into a different market segment. 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.

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. 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 SX620 features a 1/2.3-inch sensor and the Ricoh GR an APS-C sensor. The sensor area in the GR 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 SX620 has a native 4:3 aspect ratio, while the one in the GR offers a 3:2 aspect.

Canon SX620 and Ricoh GR sensor measures

Despite having a smaller sensor, the Canon SX620 offers a higher resolution of 20.2 megapixels, compared with 16.1 MP of the Ricoh GR. 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 4.79μm for the GR). However, it should be noted that the SX620 is much more recent (by 3 years) than the GR, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Canon SX620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX620 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 Ricoh GR are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

SX620 versus GR MP

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, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The SX620 and the GR 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. That said, the GR can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Canon SX620, the Ricoh GR, and comparable cameras.

The Ricoh GR 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.

The SX620 is equipped with a zoom lens, while the GR comes with a built-in prime. The SX620 has a 25-625mm f/3.2-6.6 optic and the GR offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The GR offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX620 and the GR write their files to SDXC cards. The GR supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX620 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 SX620 HS and Ricoh GR and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX620 offers wifi support, while the GR does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The SX620 is a recent model that features in the current product line-up of Canon. In contrast, the GR has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GR was succeeded by the Ricoh GR II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon SX620 or the Ricoh GR – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon PowerShot SX620 HS:

  • More detail: Offers more megapixels (20.2 vs 16.1MP) with a 10% higher linear resolution.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (97x57mm vs 117x61mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 63g or 26 percent) and hence easier to carry around.
  • 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.
  • More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
  • More modern: Reflects 3 years of technical progress since the GR launch.

ilogo

Arguments in favor of the Ricoh GR:

  • 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.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 922k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (4 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/2.8 vs f/3.2).
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More heavily discounted: Has been around for much longer (launched in April 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the GR is the clear winner of the contest (13 : 9 points). 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.

SX620 09:13 GR

How about other alternatives? Do the specifications of the Canon SX620 and the Ricoh GR place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX620 or the GR. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

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 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.
