OM System TG-7 vs Sony A1
The OM System Tough TG-7 and the Sony A1 are two digital cameras that were officially introduced, respectively, in September 2023 and January 2021. The TG-7 is a fixed lens compact, while the A1 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (TG-7) and a full frame (A1) sensor. The OM System has a resolution of 12 megapixels, whereas the Sony provides 49.8 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 OM System Tough TG-7 and the Sony A1? 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 A1 are illustrated in the side-by-side display below. 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 TG-7 can be obtained in two different colors (black, red), while the A1 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 A1 is considerably larger (66 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 A1 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 A1 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 A1 can take 530 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The TG-7 was launched at a lower price than the A1, 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.
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 are more costly to manufacture and tend to 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 A1 a full frame sensor. The sensor area in the A1 is 2979 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 A1 offers a 3:2 aspect.
With 49.8MP, the A1 offers a higher resolution than the TG-7 (12MP), but the A1 nevertheless has larger individual pixels (pixel pitch of 4.16μm 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 7 months) than the A1, 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 A1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A1 for good quality output (200 dots per inch) amounts to 43.2 x 28.8 inches or 109.7 x 73.2 cm, for very good quality (250 dpi) 34.6 x 23 inches or 87.8 x 58.5 cm, and for excellent quality (300 dpi) 28.8 x 19.2 inches or 73.2 x 48.8 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 A1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the TG-7, the A1 has the capacity to capture high quality composite images (YESMP) 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 A1 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
In terms of underlying technology, the TG-7 is build around a BSI-CMOS sensor, while the A1 uses a Stacked BSI-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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology.

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 A1 provides a better video resolution than the TG-7. It can shoot movie footage at 8k/30p, while the OM System is limited to 4K/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A1 has an electronic viewfinder (9437k 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. The adjacent table lists some of the other core features of the OM System TG-7 and Sony A1 along with similar information for a selection of comparators.

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 A1 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 A1 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 A1 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.
The TG-7 writes its imaging data to SDXC cards, while the A1 uses CFexpress (type A) or SDXC cards. The A1 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 A1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the TG-7 can use UHS-I cards (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 OM System Tough TG-7 and Sony A1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A1 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 A1 (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 A1 are recent models that are part of the current product line-up. The TG-7 replaced the earlier Olympus TG-6, while the A1 does not have a direct predecessor. Further information on the features and operation of the TG-7 and A1 can be found, respectively, in the OM System TG-7 Manual (free pdf) or the online Sony A1 Manual.
Review summary
So what is the bottom line? Is the OM System TG-7 better than the Sony A1 or vice versa? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been around for much longer (launched in January 2021).
If the count of relative strengths (bullet points above) is taken as a measure, the A1 is the clear winner of the contest (27 : 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 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 OM System TG-7 and the Sony A1 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the TG-7 or the A1. 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
