Pentax KP vs Sony A7

The Pentax KP and the Sony Alpha A7 are two enthusiast cameras that were officially introduced, respectively, in January 2017 and October 2013. The KP is a DSLR, while the A7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (KP) and a full frame (A7) sensor. The Pentax has a resolution of 24.1 megapixels, whereas the Sony provides 24 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 Pentax KP and the Sony Alpha A7? 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 KP vs Sony A7

The side-by-side display below illustrates the physical size and weight of the Pentax KP and the Sony A7. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The KP can be obtained in two different colors (black, silver), while the A7 is only available in black.

Compare KP versus A7 top
Comparison KP or A7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 is notably smaller (10 percent) than the Pentax KP. Moreover, the A7 is markedly lighter (33 percent) than the KP. 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 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 KP gets 390 shots out of its D-LI109 battery, while the A7 can take 340 images on a single charge of its NP-FW50 power pack. The power pack in the A7 can be charged via the USB port, which can be very convenient when travelling.

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

Any camera decision will obviously take relative prices into account. 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. The KP was launched at a markedly lower price (by 35 percent) than the A7, 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: Pentax KP vs Sony A7

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Pentax KP features an APS-C sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Pentax KP and Sony A7 sensor measures

Despite having a smaller sensor, the Pentax KP offers a higher resolution of 24.1 megapixels, compared with 24 MP of the Sony A7. 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 3.90μm versus 5.97μm for the A7). However, it should be noted that the KP is much more recent (by 3 years and 3 months) than the A7, 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 KP has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The A7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the A7, the KP 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 Pentax KP has a native sensitivity range from ISO 100 to ISO 819200. The corresponding ISO settings for the Sony Alpha A7 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7 provides a faster frame rate than the KP. It can shoot movie footage at 1080/60p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Pentax KP vs Sony A7

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 has an electronic viewfinder (2400k dots), while the KP 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A7 has a higher magnification than the one of the KP (0.71x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Pentax KP and Sony A7 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The KP has one, while the A7 does not. While the built-in flash of the KP is not very powerful, it can at times be useful as a fill-in light.

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 KP 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 KP 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 KP writes its imaging data to SDXC cards, while the A7 uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Pentax KP vs Sony A7

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.

It is notable that the A7 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The KP lacks such a headphone port.

The KP is a recent model that features in the current product line-up of Pentax. In contrast, the A7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Sony websites.


Review summary: Pentax KP vs Sony A7

So what conclusions can be drawn? Is there a clear favorite between the Pentax KP and the Sony A7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Sony Alpha A7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Better live-view autofocus: Features on-sensor phase-detection for quicker and more confident autofocus.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.63x).
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/6000s) to freeze action.
  • More compact: Is smaller (127x94mm vs 132x101mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 229g or 33 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been around for much longer (launched in October 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the A7 emerges as the winner of the match-up (13 : 11 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Pentax KP and the Sony A7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the KP or the A7. 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: Pentax KP vs Sony A7

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 (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.

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

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
