Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax Q and the Sony Cyber-shot DSC-HX400V? 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.
The physical size and weight of the Pentax Q and the Sony HX400V 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 HX400V 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 Sony HX400V is considerably larger (116 percent) than the Pentax Q. In this context, it is worth noting that neither the Pentax Q nor the HX400V are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX400V 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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. The HX400V was launched at a lower price than the Pentax Q, 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.
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 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.
While the two cameras under review share the same sensor size, the HX400V offers a higher resolution of 20.2 megapixels, compared with 12 MP of the Pentax Q. This megapixels advantage translates into a 30 percent gain in linear resolution. On the other hand, these sensor specs imply that the HX400V has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.53μm for the Pentax Q). However, it should be noted that the HX400V is much more recent (by 2 years and 7 months) than the Pentax Q, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the HX400V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony HX400V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX400V for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Pentax Q are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch 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 Sony Cyber-shot DSC-HX400V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the HX400V 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.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the HX400V has an electronic viewfinder (210k dots), which can be very helpful when shooting in bright sunlight. In contrast, the Pentax Q relies on live view and the rear LCD for framing. That said, the Pentax Q can be equipped with an optional viewfinder – the O-VF1. The table below summarizes some of the other core capabilities of the Pentax Q and Sony HX400V in connection with corresponding information for a sample of similar cameras.

The Pentax Q 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 Pentax Q writes its imaging data to SDXC cards, while the HX400V uses SDXC or Memory Stick PRO Duo cards.
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 Sony Cyber-shot DSC-HX400V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the HX400V offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Pentax Q does not offer wifi capability.
Travel and landscape photographers will find it useful that the HX400V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The HX400V is a recent model that features in the current product line-up of Sony. In contrast, the Pentax Q has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the Pentax Q was succeeded by the Pentax Q10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Sony websites.
So how do things add up? Is the Pentax Q better than the Sony HX400V or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Pentax Q:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (98x57mm vs 130x93mm) and thus needs less room in the bag.
- More heavily discounted: Has been available for much longer (launched in June 2011).
Advantages of the Sony Cyber-shot DSC-HX400V:
- More detail: Has more megapixels (20.2 vs 12MP), which boosts linear resolution by 30%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 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.
- Longer lasting: Gets more shots (300 versus 230) out of a single battery charge.
- 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.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 2 years and 7 months of technical progress since the Pentax Q launch.
If the number of relative strengths (bullet points above) is taken as a guide, the HX400V is the clear winner of the contest (15 : 5 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 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 Sony HX400V place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the Pentax Q and the HX400V in practical situations. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
