OM System TG-7 vs Sony RX10 III

The OM System Tough TG-7 and the Sony Cyber-shot DSC-RX10 III are two digital cameras that were officially introduced, respectively, in September 2023 and March 2016. Both the TG-7 and the RX10 III are fixed lens compact cameras that are based on a 1/2.3-inch (TG-7) and an one-inch (RX10 III) sensor. The OM System has a resolution of 12 megapixels, whereas the Sony provides 20 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the OM System TG-7 and the Sony RX10 III are illustrated 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-7 can be obtained in two different colors (black, red), while the RX10 III is only available in black.

Compare TG-7 versus RX10 III top
Comparison TG-7 or RX10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 III is considerably larger (66 percent) than the OM System TG-7. Moreover, the RX10 III is substantially heavier (322 percent) than the 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.

Concerning battery life, the TG-7 gets 330 shots out of its OM System LI-92B battery, while the RX10 III can take 420 images on a single charge of its Sony NP-FW50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 markedly lower price (by 63 percent) than the RX10 III, which puts it into a different market segment. 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. 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 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 RX10 III an one-inch sensor. The sensor area in the RX10 III is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the TG-7 has a native 4:3 aspect ratio, while the one in the RX10 III offers a 3:2 aspect.

OM System TG-7 and Sony RX10 III sensor measures

With 20MP, the RX10 III offers a higher resolution than the TG-7 (12MP), but the RX10 III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the TG-7) due to its larger sensor. However, the TG-7 is a much more recent model (by 7 years and 5 months) than the RX10 III, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony RX10 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 OM System Tough TG-7 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

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.

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 RX10 III has an electronic viewfinder (2359k 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 following table reports on some other key feature differences and similarities of the OM System TG-7, the Sony RX10 III, and comparable cameras.

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

One feature that is present on the RX10 III, but is missing on the TG-7 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 RX10 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 OM System TG-7 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.

Both the TG-7 and the RX10 III have zoom lenses built in. The TG-7 has a 25-100mm f/2.0-4.9 optic and the RX10 III offers a 24-600mm f/2.4-4.0 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the OM System. The TG-7 offers the faster maximum aperture.

The TG-7 writes its imaging data to SDXC cards, while the RX10 III uses SDXC or Memory Stick PRO Duo 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 OM System Tough TG-7 and Sony Cyber-shot DSC-RX10 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 III 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.

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.

The TG-7 is a recent model that features in the current product line-up of OM System. In contrast, the RX10 III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX10 III was succeeded by the Sony RX10 IV. Further information on the features and operation of the TG-7 and RX10 III can be found, respectively, in the OM System TG-7 Manual (free pdf) or the online Sony RX10 III Manual.

Review summary

So what is the bottom line? Is the OM System TG-7 better than the Sony RX10 III or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the OM System Tough TG-7:

  • Faster burst: Shoots at higher frequency (20 vs 14 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.4).
  • More compact: Is smaller (114x66mm vs 133x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 802g or 76 percent) and hence easier to carry around.
  • 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 into a lower priced category (63 percent cheaper at launch).
  • More modern: Reflects 7 years and 5 months of technical progress since the RX10 III launch.

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX10 III:

  • More detail: Has more megapixels (20 vs 12MP), which boosts linear resolution by 32%.
  • 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.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (420 versus 330) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been around for much longer (launched in March 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 III is the clear winner of the contest (18 : 9 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.

TG-7 09:18 RX10 III

How about other alternatives? Do the specifications of the OM System TG-7 and the Sony RX10 III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the TG-7 and the RX10 III in practical situations. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
