Olympus E-P3 vs Pentax K-1 II
The Olympus PEN E-P3 and the Pentax K-1 II are two enthusiast cameras that were officially introduced, respectively, in June 2011 and February 2018. The E-P3 is a mirrorless interchangeable lens camera, while the K-1 II is a DSLR. The cameras are based on a Four Thirds (E-P3) and a full frame (K-1 II) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Pentax provides 36.2 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-P3 and the Pentax K-1 II? 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 physical size and weight of the Olympus E-P3 and the Pentax K-1 II are illustrated 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 size dimensions are rounded to the nearest millimeter.
The E-P3 can be obtained in three different colors (black, silver, white), while the K-1 II is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 II is considerably larger (79 percent) than the Olympus E-P3. Moreover, the K-1 II is substantially heavier (174 percent) than the E-P3. It is noteworthy in this context that the K-1 II is splash and dust-proof, while the E-P3 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 E-P3 gets 330 shots out of its Olympus BLS-5 battery, while the K-1 II can take 670 images on a single charge of its Pentax D-LI90 power pack.

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 E-P3 was launched at a markedly lower price (by 60 percent) than the K-1 II, 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
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 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-P3 features a Four Thirds sensor and the Pentax K-1 II a full frame sensor. The sensor area in the K-1 II is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-P3 has a native 4:3 aspect ratio, while the one in the K-1 II offers a 3:2 aspect.
With 36.2MP, the K-1 II offers a higher resolution than the E-P3 (12.2MP), but the K-1 II nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 4.29μm for the E-P3) due to its larger sensor. Moreover, the K-1 II is a much more recent model (by 6 years and 7 months) than the E-P3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-1 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 II for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Olympus E-P3 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
Unlike the E-P3, the K-1 II 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 Olympus PEN E-P3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Pentax K-1 II are ISO 100 to ISO 819200 (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 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60i).
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the K-1 II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The table below summarizes some of the other core capabilities of the Olympus E-P3 and Pentax K-1 II in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-P3 has one, while the K-1 II does not. While the built-in flash of the E-P3 is not very powerful, it can at times be useful as a fill-in light.
The Pentax K-1 II 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.
Concerning the storage of imaging data, both the E-P3 and the K-1 II write their files to SDXC cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P3 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Olympus PEN E-P3 and Pentax K-1 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P3 does not provide wifi capability.
Studio photographers will appreciate that the Pentax K-1 II (unlike the E-P3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the K-1 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the E-P3 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-P3 was succeeded by the Olympus E-P5. Further information on the features and operation of the E-P3 and K-1 II can be found, respectively, in the Olympus E-P3 Manual (free pdf) or the online Pentax K-1 II Manual.
Review summary
So how do things add up? Is the Olympus E-P3 better than the Pentax K-1 II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the K-1 II is the clear winner of the contest (24 : 8 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.
How about other alternatives? Do the specifications of the Olympus E-P3 and the Pentax K-1 II 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-P3 or the K-1 II. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
