Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX0II 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX0 II 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 width, height and depth measures are rounded to the nearest millimeter.

The TG-5 can be obtained in two different colors (black, red), while the RX0 II 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 Olympus TG-5 is considerably larger (208 percent) than the Sony RX0 II. Moreover, the TG-5 is substantially heavier (89 percent) than the RX0 II. 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, both cameras are water-proof and can, thus, be used for underwater photography.

Concerning battery life, the RX0 II gets 240 shots out of its Sony NP-BJ1 battery, while the TG-5 can take 340 images on a single charge of its Olympus LI-92B power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 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-5 was launched at a markedly lower price (by 36 percent) than the RX0 II, which puts it into a different market segment. 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.

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony RX0 II features an one-inch sensor and the Olympus TG-5 a 1/2.3-inch sensor. The sensor area in the TG-5 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the RX0 II has a native 3:2 aspect ratio, while the one in the TG-5 offers a 4:3 aspect.

With 15.4MP, the RX0 II offers a higher resolution than the TG-5 (12MP), but the RX0 II nevertheless has larger individual pixels (pixel pitch of 2.74μm versus 1.53μm for the TG-5) due to its larger sensor. Moreover, the RX0 II is a somewhat more recent model (by 1 year and 10 months) than the TG-5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony RX0 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX0 II for good quality output (200 dots per inch) amounts to 24 x 16 inches or 61 x 40.6 cm, for very good quality (250 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm, and for excellent quality (300 dpi) 16 x 10.7 inches or 40.6 x 27.1 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 Sony Cyber-shot DSC-RX0II has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Olympus Tough TG-5 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the RX0 II is build around a CMOS sensor, while the TG-5 uses a 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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 also of capturing video footage. 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

Apart from body and sensor, cameras can and do differ across a variety of features. The RX0 II and the TG-5 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The following table reports on some other key feature differences and similarities of the Sony RX0 II, the Olympus TG-5, 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-5 has one, while the RX0 II does not. While the built-in flash of the TG-5 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 RX0 II only has 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-5 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-5 is equipped with a zoom lens, while the RX0 II comes with a built-in prime. The TG-5 has a 25-100mm f/2.0-4.9 optic and the RX0 II offers a 24mm f/4.0 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Olympus, but less tele-photo reach at the long end. The TG-5 offers the faster maximum aperture.

The RX0 II writes its imaging data to micro SDXC or Memory Stick Micro cards, while the TG-5 uses SDXC 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 Sony Cyber-shot DSC-RX0II 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 RX0 II has a microphone port, which is missing on the TG-5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

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 RX0 II is a recent model that features in the current product line-up of Sony. 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 features and operation of the RX0 II and TG-5 can be found, respectively, in the Sony RX0 II Manual (free pdf) or the online Olympus TG-5 Manual.

Review summary

So how do things add up? Is the Sony RX0 II better than the Olympus TG-5 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Sony Cyber-shot DSC-RX0II:

• More detail: Offers more megapixels (15.4 vs 12MP) with a 15% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• 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 compact: Is smaller (59x41mm vs 113x66mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 118g or 47 percent) and hence easier to carry around.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Is somewhat more recent (announced 1 year and 10 months after the TG-5).

Arguments in favor of the Olympus Tough TG-5:

• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• Faster burst: Shoots at higher frequency (20 vs 5.5 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/4.0).
• Longer lasting: Gets more shots (340 versus 240) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in May 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the RX0 II emerges as the winner of the contest (14 : 11 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 Sony RX0 II and the Olympus TG-5 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the RX0 II or the TG-5. 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 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 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 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.
