Fujifilm X-S20 vs Pentax Q

The Fujifilm X-S20 and the Pentax Q are two digital cameras that were officially introduced, respectively, in May 2023 and June 2011. Both the X-S20 and the Pentax Q are mirrorless interchangeable lens cameras that are based on an APS-C (X-S20) and a 1/2.3-inch (Pentax Q) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Pentax provides 12 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Fujifilm X-S20 and the Pentax Q are illustrated 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 X-S20 is only available in black.

Compare X-S20 versus Pentax Q top
Comparison X-S20 or Pentax Q rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax Q is considerably smaller (49 percent) than the Fujifilm X-S20. Moreover, the Pentax Q is substantially lighter (63 percent) than the X-S20. In this context, it is worth noting that neither the X-S20 nor the Pentax Q are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The power pack in the X-S20 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.

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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax Q was launched at a markedly lower price (by 50 percent) than the X-S20, which puts it into a different market segment. 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-S20 features an APS-C sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the X-S20 has a native 3:2 aspect ratio, while the one in the Pentax Q offers a 4:3 aspect.

Fujifilm X-S20 and Pentax Q sensor measures

With 26MP, the X-S20 offers a higher resolution than the Pentax Q (12MP), but the X-S20 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the X-S20 is a much more recent model (by 11 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 pixels. Coming back to sensor resolution, it should be mentioned that the X-S20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-S20 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-S20 for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 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 X-S20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X-S20 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).

In terms of underlying technology, the X-S20 is build around a BSI-CMOS sensor, while the Pentax Q uses a CMOS imager. The X-S20 uses Fujifilm's X-Trans layout of photosites, while the Pentax Q employs the more common Bayer array.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-S20 provides a higher video resolution than the Pentax Q. It can shoot video footage at 4K/60p, while the Pentax is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-S20 has an electronic viewfinder (2360k 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 following table reports on some other key feature differences and similarities of the Fujifilm X-S20, the Pentax Q, 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 X-S20 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 X-S20 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping 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 X-S20 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 Fujifilm X-S20 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 X-S20 and the Pentax Q write their files to SDXC cards. The X-S20 supports UHS-II cards (Ultra High Speed data transfer of up to 312 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 Fujifilm X-S20 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 X-S20 has a microphone port, which is missing on the Pentax Q. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The X-S20 is a recent model that features in the current product line-up of Fujifilm. In contrast, the Pentax Q has been discontinued (but 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 features and operation of the X-S20 and Pentax Q can be found, respectively, in the Fujifilm X-S20 Manual (free pdf) or the online Pentax Q Manual.

ilogo

Arguments in favor of the Pentax Q:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (98x57mm vs 128x85mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 311g or 63 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • 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 X-S20 is the clear winner of the match-up (25 : 5 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.

X-S20 25:05 Pentax Q

How about other alternatives? Do the specifications of the Fujifilm X-S20 and the Pentax Q place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 X-S20 and the Pentax Q 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.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
