Panasonic TZ90 vs Ricoh WG-6
The Panasonic Lumix DC-TZ90 (called Panasonic ZS70 in some regions) and the Ricoh WG-6 are two digital cameras that were revealed to the public, respectively, in April 2017 and February 2019. Both the TZ90 and the WG-6 are fixed lens compact cameras that are equipped with a 1/2.3-inch sensor. Both cameras offer a resolution of 20.2 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-TZ90 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.
The side-by-side display below illustrates the physical size and weight of the Panasonic TZ90 and the Ricoh WG-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 TZ90 can be obtained in two different colors (black, silver), while the WG-6 is also available in two color-versions, but different ones (black, orange).
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 somewhat larger (4 percent) than the Panasonic TZ90. However, the WG-6 is markedly lighter (24 percent) than the TZ90. It is noteworthy in this context that the WG-6 is splash and dust-proof, while the TZ90 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.
Concerning battery life, the TZ90 gets 380 shots out of its DMW-BLG10 battery, while the WG-6 can take 340 images on a single charge of its DB-110 power pack. The battery packs of both cameras can be charged via USB, 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.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
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 WG-6 was launched at a somewhat lower price (by 11 percent) than the TZ90, which makes it more attractive for photographers on a tight budget. 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.
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.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixels. This similarity in sensor specs implies that both the TZ90 and the WG-6 have the same pixel density, as well as the same pixel size. It should, however, be noted that the WG-6 is a somewhat more recent model (by 1 year and 10 months) than the TZ90, and its sensor might have benefitted from technological advances during this time. 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 Panasonic Lumix DC-TZ90 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Ricoh WG-6 are ISO 125 to ISO 6400 (no boost).
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 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, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the TZ90 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the WG-6 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic TZ90 and Ricoh WG-6 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TZ90 has a touchscreen, while the WG-6 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The TZ90 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the WG-6 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the TZ90 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
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.
Both the TZ90 and the WG-6 have zoom lenses built in. The TZ90 has a 24-720mm f/3.3-6.4 optic and the WG-6 offers a 28-140mm f/3.5-5.5 (focal lengths in full frame equivalent terms). Hence, the Panasonic 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 TZ90 offers the faster maximum aperture.
Concerning the storage of imaging data, both the TZ90 and the WG-6 write their files to SDXC cards. The TZ90 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.
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 Panasonic Lumix DC-TZ90 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 TZ90 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.
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 TZ90 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the TZ90 was succeeded by the Panasonic TZ95. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Ricoh websites.
So what is the bottom line? Is the Panasonic TZ90 better than the Ricoh WG-6 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DC-TZ90:

If the number of relative strengths (bullet points above) is taken as a guide, the TZ90 is the clear winner of the match-up (14 : 9 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 Panasonic TZ90 and the Ricoh WG-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 TZ90 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.
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.
