Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Tough TG-5 and the Olympus PEN E-P3? 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-5 and the Olympus E-P3. 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 E-P3 is available in three color-versions (black, silver, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P3 is notably larger (13 percent) than the Olympus TG-5. It is worth mentioning in this context that the TG-5 is splash and dust resistant, while the E-P3 does not feature any corresponding weather-sealing. More than that, the TG-5 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-5 has a lens built in, whereas the E-P3 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 E-P3 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the TG-5 gets 340 shots out of its Olympus LI-92B battery, while the E-P3 can take 330 images on a single charge of its Olympus BLS-5 power pack. The power pack in the TG-5 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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-5 was launched at a lower price than the E-P3, 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.

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. 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 Olympus TG-5 features a 1/2.3-inch sensor and the Olympus E-P3 a Four Thirds sensor. The sensor area in the E-P3 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of chip-set technology, the TG-5 uses a more advanced image processing engine (TruePic VIII) than the E-P3 (TruePic VI), with benefits for noise reduction, color accuracy, and processing speed.

With 12.2MP, the E-P3 offers a higher resolution than the TG-5 (12MP), but the E-P3 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 1.53μm for the TG-5) due to its larger sensor. However, the TG-5 is a much more recent model (by 5 years and 10 months) than the E-P3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Olympus Tough TG-5 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-P3 are ISO 200 to ISO 12800 (no boost).

In terms of underlying technology, the TG-5 is build around a BSI-CMOS sensor, while the E-P3 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the TG-5 provides a higher video resolution than the E-P3. It can shoot video footage at 4K/30p, while the E-P3 is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The TG-5 and the E-P3 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. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The following table reports on some other key feature differences and similarities of the Olympus TG-5, the Olympus E-P3, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-P3 has a touchscreen, while the TG-5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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.

Concerning the storage of imaging data, both the TG-5 and the E-P3 write their files to 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 Olympus Tough TG-5 and Olympus PEN E-P3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the TG-5 offers wifi support, while the E-P3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

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.

Both the TG-5 and the E-P3 have been discontinued, but can regularly be found used on ebay. The E-P3 was replaced by the Olympus E-P5, while the TG-5 was followed by the Olympus TG-6. Further information on the features and operation of the TG-5 and E-P3 can be found, respectively, in the Olympus TG-5 Manual (free pdf) or the online Olympus E-P3 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus TG-5 and the Olympus E-P3? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Olympus Tough TG-5:

• Better jpgs: Has a more modern image processing engine (TruePic VIII vs TruePic VI).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
• Faster burst: Shoots at higher frequency (20 vs 3 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 E-P3 requires a separate lens.
• More compact: Is smaller (113x66mm vs 122x69mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P3).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• 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.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 10 months of technical progress since the E-P3 launch.

Reasons to prefer the Olympus PEN E-P3:

• 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.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• More detailed LCD: Has a higher resolution rear screen (614k vs 460k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/4000s 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.
• More heavily discounted: Has been around for much longer (launched in June 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the TG-5 emerges as the winner of the contest (14 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 Olympus TG-5 and the Olympus E-P3 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-5 or the E-P3 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
