Body comparison

The physical size and weight of the Fujifilm X-A1 and the Pentax K-70 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 X-A1 can be obtained in two different colors (black, blue), while the K-70 is also available in two color-versions, but different ones (black, silver).

Size Fujifilm X-A1 vs Pentax K-70
Compare X-A1 versus K-70 top
Comparison X-A1 or K-70 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-70 is considerably larger (49 percent) than the Fujifilm X-A1. Moreover, the K-70 is substantially heavier (108 percent) than the X-A1. It is noteworthy in this context that the K-70 is splash and dust-proof, while the X-A1 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-A1 gets 350 shots out of its Fujifilm NP-W126 battery, while the K-70 can take 410 images on a single charge of its Pentax D-LI109 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-A1 was launched at a markedly lower price (by 39 percent) than the K-70, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-70 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.

Fujifilm X-A1 and Pentax K-70 sensor measures

Despite having a slightly smaller sensor, the K-70 offers a higher resolution of 24 megapixels, compared with 16 MP of the X-A1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 4.80μm for the X-A1). However, it should be noted that the K-70 is much more recent (by 2 years and 8 months) than the X-A1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the K-70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax K-70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-70 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 Fujifilm X-A1 are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

The K-70 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the X-A1, the K-70 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Fujifilm X-A1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Pentax K-70 are ISO 100 to ISO 102400 (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.

X-A1 versus K-70 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait").

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-70 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X-A1 and Pentax K-70 along with similar information for a selection of comparators.

One feature that differentiates the K-70 and the X-A1 is in-body image stabilization (IBIS). The K-70 reduces the risk of handshake-induced blur with all attached lenses, while the X-A1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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 Pentax K-70 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 X-A1 writes its imaging data to SDHC cards, while the K-70 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the K-70 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X-A1 does not feature such a mic input.

Both the X-A1 and the K-70 have been discontinued, but can regularly be found used on ebay. The X-A1 was replaced by the Fujifilm X-A2, while the K-70 does not have a direct successor. Further information on the features and operation of the X-A1 and K-70 can be found, respectively, in the Fujifilm X-A1 Manual (free pdf) or the online Pentax K-70 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Fujifilm X-A1 and the Pentax K-70? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Fujifilm X-A1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (117x67mm vs 126x93mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 358g or 52 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2013).

ilogo

Advantages of the Pentax K-70:

  • More detail: Has more megapixels (24 vs 16MP), which boosts linear resolution by 23%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • 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.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
  • 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.
  • More modern: Reflects 2 years and 8 months of technical progress since the X-A1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the K-70 is the clear winner of the contest (14 : 6 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-A1 06:14 K-70

How about other alternatives? Do the specifications of the Fujifilm X-A1 and the Pentax K-70 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 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-A1 and the K-70 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

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 (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.

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