Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-620 and the Ricoh WG-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 physical size and weight of the Olympus E-620 and the Ricoh WG-6 are illustrated 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 WG-6 can be obtained in two different colors (black, orange), while the E-620 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 Ricoh WG-6 is considerably smaller (36 percent) than the Olympus E-620. It is noteworthy in this context that the WG-6 is splash and dust-proof, while the E-620 does not feature any corresponding weather-sealing. More than that, the WG-6 is water-proof up to 20m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the WG-6 has a lens built in, whereas the E-620 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 E-620 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the WG-6 can take 340 images on a single charge of its Ricoh DB-110 power pack. The power pack in the WG-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.

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. The WG-6 was launched at a lower price than the E-620, despite having a lens built in. 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 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. 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 Olympus E-620 features a Four Thirds sensor and the Ricoh WG-6 a 1/2.3-inch sensor. The sensor area in the WG-6 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the WG-6 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the E-620. 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 4.29μm for the E-620). However, it should be noted that the WG-6 is much more recent (by 9 years and 11 months) than the E-620, 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 WG-6 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh WG-6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the WG-6 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 E-620 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Ricoh WG-6 are ISO 125 to ISO 6400 (no boost).

In terms of underlying technology, the E-620 is build around a CMOS sensor, while the WG-6 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.

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. The WG-6 indeed provides for movie recording, while the E-620 does not. The highest resolution format that the WG-6 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-620 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the WG-6 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-620 and Ricoh WG-6 in connection with corresponding information for a sample of similar cameras.

The Ricoh WG-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.

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the WG-6 uses SDXC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the WG-6 only has one slot.

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 Olympus E-620 and Ricoh WG-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-620 has a hotshoe, while the WG-6 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

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

The WG-6 is a recent model that features in the current product line-up of Ricoh. In contrast, the E-620 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-620 was succeeded by the Olympus E-600. Further information on the features and operation of the E-620 and WG-6 can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Ricoh WG-6 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-620 or the Ricoh WG-6 – 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 Olympus E-620:

• 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.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (4 vs 1 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (500 versus 340) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in February 2009).

Advantages of the Ricoh WG-6:

• More detail: Has more megapixels (20.2 vs 12.2MP), which boosts linear resolution by 29%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the E-620 requires a separate lens.
• More compact: Is smaller (118x66mm vs 130x94mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the E-620).
• 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 20m).
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 9 years and 11 months of technical progress since the E-620 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the WG-6 comes out slightly ahead of the E-620 (16 : 15 points). 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 Olympus E-620 and the Ricoh WG-6 place the cameras among the top in their class? Find out in the latest Best DSLR 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 E-620 and the WG-6 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
