Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Tough TG-4 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: Olympus TG-4 vs Ricoh WG-6

The physical size and weight of the Olympus TG-4 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 perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The TG-4 can be obtained in two different colors (black, red), while the WG-6 is also available in two color-versions, but different ones (black, orange).

Comparison TG-4 or WG-6 rear

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 notably larger (5 percent) than the Olympus TG-4. However, the WG-6 is slightly lighter (0 percent) than the TG-4. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, both cameras are water-proof and can, thus, be used for underwater photography.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 TG-4 was somewhat cheaper (by 5 percent) than the WG-6 at launch, but both cameras fall into the same price category. 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: Olympus TG-4 vs Ricoh WG-6

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 tend to be associated with larger, more expensive camera bodies 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.

Olympus TG-4 and Ricoh WG-6 sensor measures

While the two cameras under review share the same sensor size, the WG-6 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the TG-4. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the WG-6 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the TG-4). However, it should be noted that the WG-6 is much more recent (by 3 years and 10 months) than the TG-4, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Olympus TG-4 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Olympus Tough TG-4 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Ricoh WG-6 are ISO 125 to ISO 6400 (no boost).

The Olympus TG-4 and the Ricoh WG-6 both have 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 TG-4 and the WG-6 have zoom lenses built in. The TG-4 has a 25-100mm f/2.0-4.9 optic and the WG-6 offers a 28-140mm f/3.5-5.5 (focal lengths in full frame equivalent terms). Hence, the Olympus provides a wider angle of view at the short end than the Ricoh, but less tele-photo reach at the long end. The TG-4 offers the faster maximum aperture.

Concerning the storage of imaging data, both the TG-4 and the WG-6 write their files to SDXC cards. The TG-4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the WG-6 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus TG-4 vs Ricoh WG-6

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 Tough TG-4 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 TG-4 offers wifi support, while the WG-6 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The WG-6 is a recent model that features in the current product line-up of Ricoh. In contrast, the TG-4 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the TG-4 was succeeded by the Olympus TG-5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Ricoh websites.


Review summary: Olympus TG-4 vs Ricoh WG-6

So how do things add up? Is there a clear favorite between the Olympus TG-4 and the Ricoh WG-6? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Olympus Tough TG-4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Faster burst: Shoots at higher frequency (5 vs 1 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/3.5).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Longer lasting: Can take more shots (380 versus 340) on a single battery charge.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More heavily discounted: Has been available for much longer (launched in April 2015).

ilogo

Advantages of the Ricoh WG-6:

  • More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • More modern: Reflects 3 years and 10 months of technical progress since the TG-4 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the TG-4 comes out slightly ahead of the WG-6 (9 : 8 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.

TG-4 09:08 WG-6

How about other alternatives? Do the specifications of the Olympus TG-4 and the Ricoh WG-6 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 TG-4 or the WG-6 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: Olympus TG-4 vs Ricoh WG-6

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
