Olympus TG-6 vs Panasonic GX800

The Olympus Tough TG-6 and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were officially introduced, respectively, in May 2019 and January 2017. The TG-6 is a fixed lens compact, while the GX800 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (TG-6) and a Four Thirds (GX800) sensor. The Olympus has a resolution of 12 megapixels, whereas the Panasonic provides 15.8 MP.

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 Olympus Tough TG-6 and the Panasonic Lumix DMC-GX800? 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

An illustration of the physical size and weight of the Olympus TG-6 and the Panasonic GX800 is provided 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 TG-6 can be obtained in two different colors (black, red), while the GX800 is available in three color-versions (black, silver, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX800 is notably smaller (7 percent) than the Olympus TG-6. It is worth mentioning in this context that the TG-6 is splash and dust resistant, while the GX800 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.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TG-6 has a lens built in, whereas the GX800 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 GX800 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the TG-6 gets 340 shots out of its Olympus LI-92B battery, while the GX800 can take 210 images on a single charge of its Panasonic DMW-BLH7 power pack. The power pack in the TG-6 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. 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 TG-6 was launched at a lower price than the GX800, despite having a lens built in. 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.

Of the two cameras under consideration, the Olympus TG-6 features a 1/2.3-inch sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 15.8MP, the GX800 offers a higher resolution than the TG-6 (12MP), but the GX800 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 1.53μm for the TG-6) due to its larger sensor. However, the TG-6 is a much more recent model (by 2 years and 4 months) than the GX800, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic GX800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX800 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 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 Olympus Tough TG-6 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the TG-6 is build around a BSI-CMOS sensor, while the GX800 uses a 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The TG-6 and the GX800 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 table below summarizes some of the other core capabilities of the Olympus TG-6 and Panasonic GX800 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX800 has a touchscreen, while the TG-6 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 GX800 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 Olympus TG-6 and the Panasonic GX800 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.

Concerning the storage of imaging data, both the TG-6 and the GX800 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Tough TG-6 and Panasonic Lumix DMC-GX800 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 TG-6 and the GX800 have been discontinued, but can regularly be found used on ebay. The TG-6 was replaced by the OM System TG-7, while the GX800 does not have a direct successor. Further information on the features and operation of the TG-6 and GX800 can be found, respectively, in the Olympus TG-6 Manual (free pdf) or the online Panasonic GX800 Manual.

Review summary

So what conclusions can be drawn? Is the Olympus TG-6 better than the Panasonic GX800 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Olympus Tough TG-6:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/500s) to freeze action.
• Faster burst: Shoots at higher frequency (20 vs 10 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the GX800 requires a separate lens.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the GX800).
• Longer lasting: Can take more shots (340 versus 210) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 2 years and 4 months of technical progress since the GX800 launch.

Reasons to prefer the Panasonic Lumix DMC-GX800:

• More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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 flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More heavily discounted: Has been around for much longer (launched in January 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the TG-6 comes out slightly ahead of the GX800 (13 : 12 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 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 TG-6 and the Panasonic GX800 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the TG-6 or the GX800 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

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 (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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
