Pentax K-3 vs Sony WX800

The Pentax K-3 and the Sony Cyber-shot DSC-WX800 are two digital cameras that were officially introduced, respectively, in October 2013 and October 2018. The K-3 is a DSLR, while the WX800 is a fixed lens compact. The cameras are based on an APS-C (K-3) and a 1/2.3-inch (WX800) sensor. The Pentax has a resolution of 24.1 megapixels, whereas the Sony provides 18 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 K-3 and the Sony Cyber-shot DSC-WX800? 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

An illustration of the physical size and weight of the Pentax K-3 and the Sony WX800 is provided 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 width, height and depth measures are rounded to the nearest millimeter.

The K-3 can be obtained in two different colors (black, silver), while the WX800 is also available in two color-versions, but different ones (black, white).

Size Pentax K-3 vs Sony WX800
Compare K-3 versus WX800 top
Comparison K-3 or WX800 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony WX800 is considerably smaller (55 percent) than the Pentax K-3. It is worth mentioning in this context that the K-3 is splash and dust resistant, while the WX800 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the WX800 has a lens built in, whereas the K-3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the K-3 gets 560 shots out of its D-LI90 battery, while the WX800 can take 370 images on a single charge of its NP-BX1 power pack. The power pack in the WX800 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 WX800 was launched at a lower price than the K-3, despite having a lens built in. 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 size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Pentax K-3 features an APS-C sensor and the Sony WX800 a 1/2.3-inch sensor. The sensor area in the WX800 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 K-3 has a native 3:2 aspect ratio, while the one in the WX800 offers a 4:3 aspect.

Pentax K-3 and Sony WX800 sensor measures

With 24.1MP, the K-3 offers a higher resolution than the WX800 (18MP), but the K-3 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 1.25μm for the WX800) due to its larger sensor. However, the WX800 is a much more recent model (by 5 years) than the K-3, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Pentax K-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-3 for good quality output (200 dots per inch) amounts to 30.1 x 20 inch or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inch or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inch or 50.9 x 33.9 cm. The corresponding values for the Sony WX800 are 24.5 x 18.4 inch or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inch or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inch or 41.5 x 31.1 cm for excellent quality prints.

The Pentax K-3 has a native sensitivity range from ISO 100 to ISO 51200. The corresponding ISO settings for the Sony Cyber-shot DSC-WX800 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

K-3 versus WX800 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

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 WX800 provides a better video resolution than the K-3. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60i.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the WX800 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Pentax K-3, the Sony WX800, and comparable cameras.

One feature that is present on the K-3, but is missing on the WX800 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The WX800 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the K-3 does not have a selfie-screen.

The Pentax K-3 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 K-3 writes its imaging data to SDXC cards, while the WX800 uses SDXC or Memory Stick PRO Duo cards. The K-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the WX800 only has one slot. The K-3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the WX800 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 Pentax K-3 and Sony Cyber-shot DSC-WX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-3 has a hotshoe, while the WX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Pentax K-3 (unlike the WX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The WX800 is a recent model that features in the current product line-up of Sony. In contrast, the K-3 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-3 was succeeded by the Pentax K-3 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

So what is the bottom line? Is the Pentax K-3 better than the Sony WX800 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

  • Faster burst: Shoots at higher frequency (10 vs 8.3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the K-3 requires a separate lens.
  • More compact: Is smaller (102x58mm vs 131x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the K-3).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 5 years of technical progress since the K-3 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the K-3 is the clear winner of the match-up (22 : 12 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

K-3 22:12 WX800

How about other alternatives? Do the specifications of the Pentax K-3 and the Sony WX800 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 K-3 and the WX800 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 expert reviews are important. 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
