Pentax K-30 vs Sony WX800
The Pentax K-30 and the Sony Cyber-shot DSC-WX800 are two digital cameras that were announced, respectively, in May 2012 and October 2018. The K-30 is a DSLR, while the WX800 is a fixed lens compact. The cameras are based on an APS-C (K-30) and a 1/2.3-inch (WX800) sensor. The Pentax has a resolution of 16.1 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-30 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.
An illustration of the physical size and weight of the Pentax K-30 and the Sony WX800 is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.
The K-30 can be obtained in seven different colors (black, silver, blue, red, yellow, green, white), while the WX800 is available in two color-versions (black, white).
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 (53 percent) than the Pentax K-30. It is worth mentioning in this context that the K-30 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-30 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-30 gets 410 shots out of its D-LI109 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 WX800 was launched at a lower price than the K-30, 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.
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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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-30 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-30 has a native 3:2 aspect ratio, while the one in the WX800 offers a 4:3 aspect.
Despite having a smaller sensor, the WX800 offers a higher resolution of 18 megapixels, compared with 16.1 MP of the K-30. 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 1.25μm versus 4.79μm for the K-30). However, it should be noted that the WX800 is much more recent (by 6 years and 4 months) than the K-30, 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 WX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Pentax K-30 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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.
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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. 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-30. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the K-30 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-30, the Sony WX800, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The WX800 has a touchscreen, while the K-30 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.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-30 does not have a selfie-screen.
The K-30 writes its imaging data to SDXC cards, while the WX800 uses SDXC or Memory Stick PRO Duo cards.
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-30 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-30 has a hotshoe, while the WX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The WX800 is a recent model that features in the current product line-up of Sony. In contrast, the K-30 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-30 was succeeded by the Pentax K-50. 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.
So what conclusions can be drawn? Which of the two cameras – the Pentax K-30 or the Sony WX800 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Pentax K-30:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (410 versus 370) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been available for much longer (launched in May 2012).
Reasons to prefer the Sony Cyber-shot DSC-WX800:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with an integrated lens, while the K-30 requires a separate lens.
- More compact: Is smaller (102x58mm vs 130x97mm) 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-30).
- 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 6 years and 4 months of technical progress since the K-30 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the WX800 emerges as the winner of the match-up (14 : 12 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the K-30 or the WX800 perform in practice. 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.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
