Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Tough TG-5 and the Pentax Q? 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 Pentax Q. 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-5 can be obtained in two different colors (black, red), while the Pentax Q is also available in two color-versions, but different ones (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax Q is notably smaller (25 percent) than the Olympus TG-5. It is worth mentioning in this context that the TG-5 is splash and dust resistant, while the Pentax Q 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 Pentax Q is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

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 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The TG-5 was launched at a lower price than the Pentax Q, 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 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.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12 megapixels. This similarity in sensor specs implies that both the TG-5 and the Pentax Q have the same pixel density, as well as the same pixel size. It should, however, be noted that the TG-5 is much more recent (by 5 years and 10 months) than the Pentax Q, and its sensor will have benefitted from technological advances during this time.

The Olympus Tough TG-5 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).

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

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 Pentax Q. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The TG-5 and the Pentax Q 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 Pentax Q can be equipped with an optional viewfinder – the O-VF1. The adjacent table lists some of the other core features of the Olympus TG-5 and Pentax Q along with similar information for a selection of comparators.

The Olympus TG-5 and the Pentax Q 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.

Concerning the storage of imaging data, both the TG-5 and the Pentax Q write their files to SDXC cards. The TG-5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Pentax Q cannot take advantage of Ultra High Speed SD cards.

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 Pentax Q 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 Pentax Q 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 Pentax Q have been discontinued, but can regularly be found used on ebay. The Pentax Q was replaced by the Pentax Q10, while the TG-5 was followed by the Olympus TG-6. Further information on the features and operation of the TG-5 and Pentax Q can be found, respectively, in the Olympus TG-5 Manual (free pdf) or the online Pentax Q Manual.

Review summary

So how do things add up? Is there a clear favorite between the Olympus TG-5 and the Pentax Q? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Olympus Tough TG-5:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Faster burst: Shoots at higher frequency (20 vs 1.5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the Pentax Q requires a separate lens.
• Longer lasting: Can take more shots (340 versus 230) on a single battery charge.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• 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 Pentax Q launch.

Arguments in favor of the Pentax Q:

• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (98x57mm vs 113x66mm) and will fit more readily into a bag.
• 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 relative strengths (bullet points above) is taken as a measure, the TG-5 is the clear winner of the match-up (12 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

How about other alternatives? Do the specifications of the Olympus TG-5 and the Pentax Q 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 says little about, for example, the shooting experience and imaging performance of the TG-5 and the Pentax Q in practical situations. 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 where reviews by experts come in. 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
