Pentax K-50 vs Sony A3000
The Pentax K-50 and the Sony Alpha A3000 are two digital cameras that were officially introduced, respectively, in June 2013 and August 2013. The K-50 is a DSLR, while the A3000 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Pentax has a resolution of 16.1 megapixels, whereas the Sony provides 19.8 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-50 and the Sony Alpha A3000? 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
The side-by-side display below illustrates the physical size and weight of the Pentax K-50 and the Sony A3000. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The K-50 can be obtained in three different colors (black, red, white), while the A3000 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A3000 is notably smaller (8 percent) than the Pentax K-50. Moreover, the A3000 is substantially lighter (37 percent) than the K-50. It is worth mentioning in this context that the K-50 is splash and dust resistant, while the A3000 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 K-50 gets 410 shots out of its Pentax D-LI109 battery, while the A3000 can take 470 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

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 A3000 was launched at a markedly lower price (by 45 percent) than the K-50, 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 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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A3000 is 3 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.
Despite having a slightly smaller sensor, the A3000 offers a higher resolution of 19.8 megapixels, compared with 16.1 MP of the K-50. 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 4.25μm versus 4.77μm for the K-50). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Sony A3000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A3000 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Pentax K-50 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.
The Pentax K-50 has a native sensitivity range from ISO 100 to ISO 51200. The corresponding ISO settings for the Sony Alpha A3000 are ISO 100 to ISO 16000 (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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A3000 provides a faster frame rate than the K-50. It can shoot movie footage at 1080/60i, while the Pentax is limited to 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A3000 has an electronic viewfinder (202k dots), while the K-50 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 K-50 has a higher magnification than the one of the A3000 (0.61x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Pentax K-50, the Sony A3000, and comparable cameras.

One feature that differentiates the K-50 and the A3000 is in-body image stabilization (IBIS). The K-50 reduces the risk of handshake-induced blur with all attached lenses, while the A3000 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The Pentax K-50 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-50 writes its imaging data to SDXC cards, while the A3000 uses SDXC or Memory Stick PRO Duo 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-50 and Sony Alpha A3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the K-50 and the A3000 have been discontinued, but can regularly be found used on ebay. The K-50 was replaced by the Pentax K-70, while the A3000 does not have a direct successor. Further information on the features and operation of the K-50 and A3000 can be found, respectively, in the Pentax K-50 Manual (free pdf) or the online Sony A3000 Manual.
Review summary
So how do things add up? Which of the two cameras – the Pentax K-50 or the Sony A3000 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Pentax K-50:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.61x vs 0.47x).
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 2.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Sharper images: Has hand-shake reducing image stabilization built-in.
Arguments in favor of the Sony Alpha A3000:
- More detail: Has more megapixels (19.8 vs 16.1MP), which boosts linear resolution by 11%.
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- More framing info: Has an electronic viewfinder that displays shooting data.
- Less heavy: Has a lower weight (by 239g or 37 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (470 versus 410) out of a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (8 points each). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 K-50 and the Sony A3000 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 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-50 or the A3000 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
