Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax Q and the Sony Cyber-shot DSC-RX100 IV? 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: Pentax Q vs Sony RX100 IV

An illustration of the physical size and weight of the Pentax Q and the Sony RX100 IV is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

The Pentax Q can be obtained in two different colors (black, white), while the RX100 IV is only available in black.

Comparison Pentax Q or RX100 IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 IV is notably larger (6 percent) than the Pentax Q. In this context, it is worth noting that neither the Pentax Q nor the RX100 IV are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV 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 RX100 IV can be charged via the USB port, 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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

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.

 

Sensor comparison: Pentax Q vs Sony RX100 IV

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Pentax Q features a 1/2.3-inch sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV 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 RX100 IV offers a 3:2 aspect.

Pentax Q and Sony RX100 IV sensor measures

With 20MP, the RX100 IV offers a higher resolution than the Pentax Q (12MP), but the RX100 IV nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the RX100 IV is a much more recent model (by 3 years and 11 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 Sony RX100 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 IV for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 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-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

Pentax Q versus RX100 IV MP

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. Of the two cameras under consideration, the RX100 IV offers substantially better image quality than the Pentax Q (overall score 23 points higher). The advantage is based on 2.6 bits higher color depth, 1.5 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.

The RX100 IV 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX100 IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

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 RX100 IV uses SDXC or Memory Stick PRO Duo cards. The RX100 IV 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: Pentax Q vs Sony RX100 IV

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.

If the count of individual advantages (bullet points above) is taken as a guide, the RX100 IV is the clear winner of the contest (18 : 4 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 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.

Pentax Q 04:18 RX100 IV

How about other alternatives? Do the specifications of the Pentax Q and the Sony RX100 IV 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 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 RX100 IV in practical situations. 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: Pentax Q vs Sony RX100 IV

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 (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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
