Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN-F and the Pentax K-3? 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: Olympus PEN-F vs Pentax K-3
An illustration of the physical size and weight of the Olympus PEN-F and the Pentax K-3 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 size dimensions are rounded to the nearest millimeter.
Both cameras are available in two different colors (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-3 is considerably larger (46 percent) than the Olympus PEN-F. Moreover, the K-3 is substantially heavier (87 percent) than the PEN-F. It is noteworthy in this context that the K-3 is splash and dust-proof, while the PEN-F 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The PEN-F was somewhat cheaper (by 8 percent) than the K-3 at launch, but both cameras fall into the same price category. 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.
Sensor comparison: Olympus PEN-F vs Pentax K-3
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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus PEN-F features a Four Thirds sensor and the Pentax K-3 an APS-C sensor. The sensor area in the K-3 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 PEN-F has a native 4:3 aspect ratio, while the one in the K-3 offers a 3:2 aspect.
With 24.1MP, the K-3 offers a higher resolution than the PEN-F (20.2MP), but the K-3 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 3.34μm for the PEN-F) due to its larger sensor. However, the PEN-F is a much more recent model (by 2 years and 3 months) than the K-3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 Olympus PEN-F are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.
Unlike the K-3, the PEN-F has the capacity to capture high quality composite images (40MP) 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-F has a native sensitivity range from ISO 80 to ISO 25600. The corresponding ISO settings for the Pentax K-3 are ISO 100 to ISO 51200 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the K-3 has a markedly higher DXO score than the PEN-F (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 1 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the PEN-F provides a higher frame rate than the K-3. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/60i.
Feature comparison: Olympus PEN-F vs Pentax K-3
Beyond body and sensor, cameras can and do differ across a range of features. For example, the PEN-F has an electronic viewfinder (2360k dots), while the K-3 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-3 has a higher magnification than the one of the PEN-F (0.63x vs 0.62x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus PEN-F and Pentax K-3 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 PEN-F has a touchscreen, while the K-3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The PEN-F 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-3 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 PEN-F 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 PEN-F and the Pentax K-3 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 PEN-F and the K-3 write their files to SDXC cards. The K-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the PEN-F only has one slot. The PEN-F supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the K-3 can use UHS-I cards (up to 104 MB/s).
Connectivity comparison: Olympus PEN-F vs Pentax K-3
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-F and Pentax K-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the PEN-F offers wifi support, while the K-3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Pentax K-3 (unlike the PEN-F) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The PEN-F is a recent model that features in the current product line-up of Olympus. 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 Olympus and Pentax websites.
Review summary: Olympus PEN-F vs Pentax K-3
So how do things add up? Which of the two cameras – the Olympus PEN-F or the Pentax K-3 – 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.
Advantages of the Olympus PEN-F:
- High quality composites: Can combine several shots after pixel-shifting its sensor.

- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in October 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the K-3 emerges as the winner of the match-up (17 : 14 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 PEN-F and the Pentax K-3 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 says little about, for example, the shooting experience and imaging performance of the PEN-F and the K-3 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: Olympus PEN-F vs Pentax K-3
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 (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 review scores listed above should be treated 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
