Fujifilm X-A5 vs Pentax K-S2
The Fujifilm X-A5 and the Pentax K-S2 are two digital cameras that were revealed to the public, respectively, in January 2018 and February 2015. The X-A5 is a mirrorless interchangeable lens camera, while the K-S2 is a DSLR. Both cameras are equipped with an APS-C sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Pentax 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 Fujifilm X-A5 and the Pentax K-S2? 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 Fujifilm X-A5 and the Pentax K-S2. 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 measures are rounded to the nearest millimeter.
The X-A5 can be obtained in three different colors (silver, brown, pink), while the K-S2 is available in six color-versions (black, grey, pink, orange, green, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-S2 is notably larger (41 percent) than the Fujifilm X-A5. Moreover, the K-S2 is substantially heavier (88 percent) than the X-A5. It is noteworthy in this context that the K-S2 is splash and dust-proof, while the X-A5 does not feature any corresponding weather-sealing.
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.
Concerning battery life, the X-A5 gets 450 shots out of its Fujifilm NP-W126S battery, while the K-S2 can take 410 images on a single charge of its Pentax D-LI109 power pack. The power pack in the X-A5 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-A5 was launched at a markedly lower price (by 47 percent) than the K-S2, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-S2 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the X-A5 offers a higher resolution than the K-S2 (20MP), but the X-A5 has smaller individual pixels (pixel pitch of 3.92μm versus 4.28μm for the K-S2). However, the X-A5 is a much more recent model (by 2 years and 11 months) than the K-S2, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the K-S2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-A5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A5 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Pentax K-S2 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The X-A5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-A5 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Pentax K-S2 are ISO 100 to ISO 51200 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-A5 provides a higher video resolution than the K-S2. It can shoot video footage at 4K/15p, 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. For example, the K-S2 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A5 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X-A5 and Pentax K-S2 in connection with corresponding information for a sample of similar 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-A5 has a touchscreen, while the K-S2 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.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-A5 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-A5 and the Pentax K-S2 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-A5 and the K-S2 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-A5 and Pentax K-S2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X-A5 and the K-S2 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Fujifilm and Pentax. Further information on the features and operation of the X-A5 and K-S2 can be found, respectively, in the Fujifilm X-A5 Manual (free pdf) or the online Pentax K-S2 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Fujifilm X-A5 or the Pentax K-S2 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Fujifilm X-A5:
- More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video: Provides higher definition movie capture (4K/15p vs 1080/30p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (117x68mm vs 123x91mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 317g or 47 percent) and hence easier to carry around.
- Easier travel charging: Can be conveniently charged via its USB port.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
- More modern: Reflects 2 years and 11 months of technical progress since the K-S2 launch.
Reasons to prefer the Pentax K-S2:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been around for much longer (launched in February 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the X-A5 is the clear winner of the match-up (14 : 8 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.
How about other alternatives? Do the specifications of the Fujifilm X-A5 and the Pentax K-S2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the X-A5 and the K-S2 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
