Olympus TG-4 vs Sony A7R

The Olympus Tough TG-4 and the Sony Alpha A7R are two digital cameras that were announced, respectively, in April 2015 and October 2013. The TG-4 is a fixed lens compact, while the A7R is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (TG-4) and a full frame (A7R) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 36.2 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 Olympus Tough TG-4 and the Sony Alpha A7R? 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 A7R. 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 dimensions are rounded to the nearest millimeter.

The TG-4 can be obtained in two different colors (black, red), while the A7R is only available in black.

Compare TG-4 versus A7R top
Comparison TG-4 or A7R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R is considerably larger (61 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 A7R 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 and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the TG-4 gets 380 shots out of its LI-92B battery, while the A7R can take 340 images on a single charge of its NP-FW50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

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-4 was launched at a lower price than the A7R, 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 size of the imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus TG-4 features a 1/2.3-inch sensor and the Sony A7R a full frame sensor. The sensor area in the A7R 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-4 has a native 4:3 aspect ratio, while the one in the A7R offers a 3:2 aspect.

Olympus TG-4 and Sony A7R sensor measures

With 36.2MP, the A7R offers a higher resolution than the TG-4 (15.9MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 1.33μm for the TG-4) due to its larger sensor. However, the TG-4 is a somewhat more recent model (by 1 year and 5 months) than the A7R, and its sensor might 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 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 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 Olympus Tough TG-4 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha A7R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

In terms of underlying technology, the TG-4 is build around a BSI-CMOS sensor, while the A7R uses a 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.

TG-4 versus A7R MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R provides a faster frame rate than the TG-4. It can shoot movie footage at 1080/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R has an electronic viewfinder (2400k 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 A7R, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The TG-4 has one, while the A7R 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 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 A7R 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 Olympus Tough TG-4 and Sony Alpha A7R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R 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.

Both the TG-4 and the A7R have been discontinued, but can regularly be found used on ebay. The A7R was replaced by the Sony A7R II, while the TG-4 was followed by the Olympus TG-5. Further information on the features and operation of the TG-4 and A7R can be found, respectively, in the Olympus TG-4 Manual (free pdf) or the online Sony A7R Manual.

Review summary

So what is the bottom line? Is the Olympus TG-4 better than the Sony A7R or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Olympus Tough TG-4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Has a lens built-in, whereas the A7R requires a separate lens.
  • More compact: Is smaller (112x66mm vs 127x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the A7R).
  • Longer lasting: Can take more shots (380 versus 340) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 15m).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Is somewhat more recent (announced 1 year and 5 months after the A7R).

ilogo

Reasons to prefer the Sony Alpha A7R:

  • More detail: Has more megapixels (36.2 vs 15.9MP), which boosts linear resolution by 54%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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 video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • 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.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 460k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • 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 on the market for longer (launched in October 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the A7R is the clear winner of the contest (17 : 13 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-4 13:17 A7R

How about other alternatives? Do the specifications of the Olympus TG-4 and the Sony A7R 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 incomplete and does no justice, for example, to the way the TG-4 or the A7R perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
