OM System TG-7 vs Sony A7R IVA
The OM System Tough TG-7 and the Sony Alpha A7R IVA are two digital cameras that were announced, respectively, in September 2023 and April 2021. The TG-7 is a fixed lens compact, while the A7R IVA is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (TG-7) and a full frame (A7R IVA) sensor. The OM System has a resolution of 12 megapixels, whereas the Sony provides 60.2 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 OM System Tough TG-7 and the Sony Alpha A7R IVA? 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 physical size and weight of the OM System TG-7 and the Sony A7R IVA 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-7 can be obtained in two different colors (black, red), while the A7R IVA 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 A7R IVA is considerably larger (65 percent) than the OM System TG-7. 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-7 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-7 has a lens built in, whereas the A7R IVA 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 A7R IVA and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the TG-7 gets 330 shots out of its OM System LI-92B battery, while the A7R IVA can take 670 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 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 TG-7 was launched at a lower price than the A7R IVA, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 OM System TG-7 features a 1/2.3-inch sensor and the Sony A7R IVA a full frame sensor. The sensor area in the A7R IVA is 2936 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-7 has a native 4:3 aspect ratio, while the one in the A7R IVA offers a 3:2 aspect.
With 60.2MP, the A7R IVA offers a higher resolution than the TG-7 (12MP), but the A7R IVA nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.53μm for the TG-7) due to its larger sensor. However, the TG-7 is a much more recent model (by 2 years and 5 months) than the A7R IVA, 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 A7R IVA has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A7R IVA implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IVA for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the OM System TG-7 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 A7R IVA has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the TG-7, the A7R IVA has the capacity to capture high quality composite images (241MP) 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 OM System Tough TG-7 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sony Alpha A7R IVA are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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, and both provide the same movie specifications (4K/30p).
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7R IVA has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the TG-7 relies on live view and the rear LCD for framing.

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-7 has one, while the A7R IVA does not. While the built-in flash of the TG-7 is not very powerful, it can at times be useful as a fill-in light.
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 A7R IVA 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 OM System TG-7 and the Sony A7R IVA 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-7 and the A7R IVA write their files to SDXC cards. The A7R IVA features dual card slots, which can be very useful in case a memory card fails. In contrast, the TG-7 only has one slot. The A7R IVA supports UHS-II cards (on both slots), while the TG-7 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.

It is notable that the A7R IVA has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The TG-7 does not feature such a mic input.
Studio photographers will appreciate that the Sony A7R IVA (unlike the TG-7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the TG-7 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the TG-7 and the A7R IVA are recent models that are part of the current product line-up. The A7R IVA replaced the earlier Sony A7R III, while the TG-7 followed on from the Olympus TG-6. Further information on the features and operation of the TG-7 and A7R IVA can be found, respectively, in the OM System TG-7 Manual (free pdf) or the online Sony A7R IVA Manual.
Review summary
So what conclusions can be drawn? Is there a clear favorite between the OM System TG-7 and the Sony A7R IVA? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the OM System Tough TG-7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

- More heavily discounted: Has been around for much longer (launched in April 2021).
If the count of relative strengths (bullet points above) is taken as a measure, the A7R IVA is the clear winner of the contest (26 : 10 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 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 OM System TG-7 and the Sony A7R IVA 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-7 or the A7R IVA perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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. 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.
