Pentax Q vs Canon G7 X
The Pentax Q and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in June 2011 and September 2014. The Pentax Q is a mirrorless interchangeable lens camera, while the G7X is a fixed lens compact. The cameras are based on a 1/2.3-inch (Pentax Q) and an one-inch (G7X) sensor. The Pentax has a resolution of 12 megapixels, whereas the Canon provides 20 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 Pentax Q and the Canon PowerShot G7 X? 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 physical size and weight of the Pentax Q and the Canon G7 X 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 size dimensions are rounded to the nearest millimeter.
The Pentax Q can be obtained in two different colors (black, white), while the G7X 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 Canon G7 X is notably larger (11 percent) than the Pentax Q. In this context, it is worth noting that neither the Pentax Q nor the G7X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will naturally be influenced heavily by the price. 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. 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 sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Pentax Q features a 1/2.3-inch sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X 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 Pentax Q has a native 4:3 aspect ratio, while the one in the G7X offers a 3:2 aspect.
With 20MP, the G7X offers a higher resolution than the Pentax Q (12MP), but the G7X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the G7X is a much more recent model (by 3 years and 2 months) than the Pentax Q, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X 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 Pentax Q 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 Pentax Q has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Canon PowerShot G7 X are ISO 125 to ISO 12800 (no boost).
In terms of underlying technology, the Pentax Q is build around a CMOS sensor, while the G7X 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 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"). Of the two cameras under consideration, the G7X offers substantially better image quality than the Pentax Q (overall score 24 points higher). The advantage is based on 2.8 bits higher color depth, 1.6 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the G7X provides a faster frame rate than the Pentax Q. It can shoot movie footage at 1080/60p, while the Pentax is limited to 1080/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. The Pentax Q and the G7X 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the Pentax Q has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The G7X has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the Pentax Q does not have a selfie-screen.The Pentax Q and the Canon G7 X 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 Pentax Q and the G7X write their files to SDXC cards. The G7X 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 Pentax Q and Canon PowerShot G7 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Pentax Q has a hotshoe, while the G7X does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the Pentax Q and the G7X have been discontinued, but can regularly be found used on ebay. The Pentax Q was replaced by the Pentax Q10, while the G7X was followed by the Canon G7 X Mark II. Further information on the features and operation of the Pentax Q and G7X can be found, respectively, in the Pentax Q Manual (free pdf) or the online Canon G7 X Manual.
Review summary
So how do things add up? Which of the two cameras – the Pentax Q or the Canon G7 X – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Pentax Q:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been available for much longer (launched in June 2011).
Arguments in favor of the Canon PowerShot G7 X:
- More detail: Has more megapixels (20 vs 12MP), which boosts linear resolution by 32%.
- Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6.5 vs 1.5 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the Pentax Q necessitates an extra lens.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 3 years and 2 months of technical progress since the Pentax Q launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X is the clear winner of the contest (16 : 4 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Pentax Q and the Canon G7 X place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the Pentax Q or the G7X perform in practice. 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 where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
