Olympus TG-4 vs Sony A7 IV
The Olympus Tough TG-4 and the Sony Alpha A7 IV are two digital cameras that were officially introduced, respectively, in April 2015 and October 2021. The TG-4 is a fixed lens compact, while the A7 IV is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (TG-4) and a full frame (A7 IV) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 32.7 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-4 and the Sony Alpha A7 IV? 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 side-by-side display below illustrates the physical size and weight of the Olympus TG-4 and the Sony A7 IV. 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 measures are rounded to the nearest millimeter.
The TG-4 can be obtained in two different colors (black, red), while the A7 IV 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 Sony A7 IV is considerably larger (70 percent) than the Olympus 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, the TG-4 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-4 has a lens built in, whereas the A7 IV 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 A7 IV and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the TG-4 gets 380 shots out of its Olympus LI-92B battery, while the A7 IV can take 580 images on a single charge of its Sony NP-FZ100 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. 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 obviously take relative prices into account. 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 TG-4 was launched at a lower price than the A7 IV, 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. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-4 features a 1/2.3-inch sensor and the Sony A7 IV a full frame sensor. The sensor area in the A7 IV is 2964 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the TG-4 has a native 4:3 aspect ratio, while the one in the A7 IV offers a 3:2 aspect.
With 32.7MP, the A7 IV offers a higher resolution than the TG-4 (15.9MP), but the A7 IV nevertheless has larger individual pixels (pixel pitch of 5.12μm versus 1.33μm for the TG-4) due to its larger sensor. Moreover, the A7 IV is a much more recent model (by 6 years and 6 months) than the TG-4, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A7 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A7 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 IV for good quality output (200 dots per inch) amounts to 35 x 23.4 inches or 89 x 59.3 cm, for very good quality (250 dpi) 28 x 18.7 inches or 71.2 x 47.5 cm, and for excellent quality (300 dpi) 23.4 x 15.6 inches or 59.3 x 39.6 cm. The corresponding values for the Olympus TG-4 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The A7 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus Tough TG-4 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha A7 IV are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. 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 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7 IV provides a better video resolution than the TG-4. It can shoot movie footage at 4K/60p, while the Olympus is limited to 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 IV has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the TG-4 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Olympus TG-4, the Sony A7 IV, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The TG-4 has one, while the A7 IV does not. While the built-in flash of the TG-4 is not very powerful, it can at times be useful as a fill-in light.
The A7 IV has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the TG-4 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 A7 IV 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-4 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 TG-4 writes its imaging data to SDXC cards, while the A7 IV uses CFexpress (type A) or SDXC cards. The A7 IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the TG-4 only has one slot. The A7 IV supports UHS-II cards (on both slots), while the TG-4 can use UHS-I cards.
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-4 and Sony Alpha A7 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 IV has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The TG-4 does not feature such a mic input.
Travel and landscape photographers will find it useful that the TG-4 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The A7 IV is a recent model that features in the current product line-up of Sony. In contrast, the TG-4 has been discontinued (but 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 features and operation of the TG-4 and A7 IV can be found, respectively, in the Olympus TG-4 Manual (free pdf) or the online Sony A7 IV Manual.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 IV is the clear winner of the contest (27 : 10 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-4 and the Sony A7 IV 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 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 TG-4 and the A7 IV in practical situations. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
