Pentax K-1 versus Fujifilm X-T2

The Pentax K-1 and the Fujifilm X-T2 are two enthusiast cameras that were officially introduced, respectively, in February 2016 and July 2016. The K-1 is a DSLR, while the X-T2 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (K-1) and an APS-C (X-T2) sensor. The Pentax has a resolution of 36.2 megapixel, whereas the Fujifilm provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Pentax K-1 vs Fujifilm X-T2

The side-by-side display below illustrates the physical size and weight of the Pentax K-1 and the Fujifilm X-T2. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the K-1 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-T2 is notably smaller (19 percent) than the Pentax K-1. Moreover, the X-T2 is substantially lighter (50 percent) than the K-1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 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 K-1 gets 760 shots out of its D-LI90 battery, while the X-T2 can take 340 images on a single charge of its NP-W126S power pack.

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.

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-T2 was launched at a somewhat lower price (by 11 percent) than the K-1, which makes it more attractive for photographers on a tight budget. 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: Pentax K-1 vs Fujifilm X-T2

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Pentax K-1 features a full frame sensor and the Fujifilm X-T2 an APS-C sensor. The sensor area in the X-T2 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Pentax K-1 and Fujifilm X-T2 sensor measures

With 36.2MP, the K-1 offers a higher resolution than the X-T2 (24MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.92μm for the X-T2) due to its larger sensor. However, the X-T2 is a somewhat more recent model (by 4 months) than the K-1, and its sensor might 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

Unlike the X-T2, the K-1 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).

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 X-T2 provides a better video resolution than the K-1. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Pentax K-1 vs Fujifilm X-T2

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T2 has an electronic viewfinder (2360k dots), while the K-1 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Pentax K-1 and Fujifilm X-T2 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The X-T2 is a current model that online retailers, such as amazon, will have in stock. In contrast, the K-1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-1 was succeeded by the Pentax K-1 II.

Review summary: Pentax K-1 vs Fujifilm X-T2

So what conclusions can be drawn? Which of the two cameras – the Pentax K-1 or the Fujifilm X-T2 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Pentax K-1:

  • More detail: Offers more megapixels (36.2 vs 24MP) with a 23% higher linear resolution.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Can take more shots (760 versus 340) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been on the market for longer (launched in February 2016).

ilogo

Reasons to prefer the Fujifilm X-T2:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Faster burst: Shoots at higher frequency (14 vs 4.4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (133x92mm vs 137x110mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 503g or 50 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the K-1 emerges as the winner of the contest (10 : 8 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.

K-1 10:08 X-T2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the K-1 and the X-T2 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. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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, please note that some of the review sites have changed their methodology and reporting over time.
