Olympus E-M5 III vs TG-5
The Olympus OM-D E-M5 Mark III and the Olympus Tough TG-5 are two digital cameras that were announced, respectively, in October 2019 and May 2017. The E-M5 III is a mirrorless interchangeable lens camera, while the TG-5 is a fixed lens compact. The cameras are based on a Four Thirds (E-M5 III) and a 1/2.3-inch (TG-5) sensor. The E-M5 III has a resolution of 20.2 megapixels, whereas the TG-5 provides 12 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 OM-D E-M5 Mark III and the Olympus Tough TG-5? 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 Olympus E-M5 III and the Olympus TG-5. 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 E-M5 III can be obtained in two different colors (black, silver), while the TG-5 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus TG-5 is considerably smaller (30 percent) than the Olympus E-M5 III. 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, the TG-5 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-5 has a lens built in, whereas the E-M5 III 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-M5 III and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-M5 III gets 310 shots out of its BLS-50 battery, while the TG-5 can take 340 images on a single charge of its LI-92B power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. 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-5 was launched at a lower price than the E-M5 III, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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-M5 III features a Four Thirds sensor and the Olympus TG-5 a 1/2.3-inch sensor. The sensor area in the TG-5 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.
With 20.2MP, the E-M5 III offers a higher resolution than the TG-5 (12MP), but the E-M5 III nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.53μm for the TG-5) due to its larger sensor. Moreover, the E-M5 III is a much more recent model (by 2 years and 5 months) than the TG-5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M5 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Olympus E-M5 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 III 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 TG-5 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 E-M5 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the TG-5, the E-M5 III has the capacity to capture high quality composite images (80MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Olympus OM-D E-M5 Mark III has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Olympus Tough TG-5 are ISO 100 to ISO 12800 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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, but the TG-5 provides a faster frame rate than the E-M5 III. It can shoot movie footage at 4K/30p, while the E-M5 III is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the TG-5 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-M5 III and Olympus TG-5 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M5 III has a touchscreen, while the TG-5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The E-M5 III 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 TG-5 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 E-M5 III 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 E-M5 III and the Olympus TG-5 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 E-M5 III and the TG-5 write their files to SDXC cards. The E-M5 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the TG-5 can use UHS-I cards (up to 104 MB/s).
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 OM-D E-M5 Mark III and Olympus Tough TG-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 III has a hotshoe, while the TG-5 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 TG-5 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The E-M5 III is a recent model that features in the current product line-up of Olympus. In contrast, the TG-5 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the TG-5 was succeeded by the Olympus TG-6. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.
So how do things add up? Is the Olympus E-M5 III better than the Olympus TG-5 or vice versa? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 III is the clear winner of the match-up (21 : 11 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.
How about other alternatives? Do the specifications of the Olympus E-M5 III and the Olympus TG-5 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the E-M5 III and the TG-5 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], 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 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
