Olympus E-PL10 vs Pentax K-50
The Olympus PEN E-PL10 and the Pentax K-50 are two digital cameras that were revealed to the public, respectively, in October 2019 and June 2013. The E-PL10 is a mirrorless interchangeable lens camera, while the K-50 is a DSLR. The cameras are based on a Four Thirds (E-PL10) and an APS-C (K-50) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Pentax provides 16.1 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 Olympus PEN E-PL10 and the Pentax K-50? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-PL10 and the Pentax K-50. 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 size dimensions are rounded to the nearest millimeter.
The E-PL10 can be obtained in four different colors (black, brown, blue, white), while the K-50 is available in three color-versions (black, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-50 is considerably larger (58 percent) than the Olympus E-PL10. Moreover, the K-50 is substantially heavier (71 percent) than the E-PL10. It is noteworthy in this context that the K-50 is splash and dust-proof, while the E-PL10 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 two cameras under review were launched at the same price and fall into the same market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
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 Olympus E-PL10 features a Four Thirds sensor and the Pentax K-50 an APS-C sensor. The sensor area in the K-50 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-PL10 has a native 4:3 aspect ratio, while the one in the K-50 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16.1MP, the K-50 offers a higher resolution than the E-PL10 (15.9MP), but the K-50 nevertheless has larger individual pixels (pixel pitch of 4.77μm versus 3.76μm for the E-PL10) due to its larger sensor. However, the E-PL10 is a much more recent model (by 6 years and 4 months) than the K-50, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Olympus PEN E-PL10 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Pentax K-50 are ISO 100 to ISO 51200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-PL10 provides a higher video resolution than the K-50. It can shoot video 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-50 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL10 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-PL10 and Pentax K-50 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-PL10 has a touchscreen, while the K-50 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The E-PL10 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the K-50 does not have a selfie-screen.
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 E-PL10 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 Olympus E-PL10 and the Pentax K-50 both have 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.
Concerning the storage of imaging data, both the E-PL10 and the K-50 write their files to SDXC cards. The E-PL10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the K-50 cannot take advantage of Ultra High Speed SD 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 Olympus PEN E-PL10 and Pentax K-50 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL10 offers wifi support, while the K-50 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The E-PL10 is a recent model that features in the current product line-up of Olympus. In contrast, the K-50 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-50 was succeeded by the Pentax K-70. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Pentax websites.
So what conclusions can be drawn? Is the Olympus E-PL10 better than the Pentax K-50 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Olympus PEN E-PL10:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (8.6 vs 6 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (117x68mm vs 130x97mm) and thus needs less room in the bag.

Arguments in favor of the Pentax K-50:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
- Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More heavily discounted: Has been around for much longer (launched in June 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the E-PL10 is the clear winner of the match-up (14 : 5 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. 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.
How about other alternatives? Do the specifications of the Olympus E-PL10 and the Pentax K-50 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the E-PL10 or the K-50 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.
This is why expert reviews are important. 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 review scores listed above should be treated 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
