Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN-F and the Pentax 645Z? 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 645Z
An illustration of the physical size and weight of the Olympus PEN-F and the Pentax 645Z is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.
The PEN-F can be obtained in two different colors (black, silver), while the 645Z 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 Pentax 645Z is considerably larger (103 percent) than the Olympus PEN-F. Moreover, the 645Z is substantially heavier (263 percent) than the PEN-F. It is noteworthy in this context that the 645Z 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.

Any camera decision will obviously take relative prices into account. 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 PEN-F was launched at a markedly lower price (by 86 percent) than the 645Z, 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: Olympus PEN-F vs Pentax 645Z
The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Olympus PEN-F features a Four Thirds sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 539 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 0.79. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 51.1MP, the 645Z offers a higher resolution than the PEN-F (20.2MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 3.34μm for the PEN-F) due to its larger sensor. However, the PEN-F is a somewhat more recent model (by 1 year and 9 months) than the 645Z, and its sensor might 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 645Z implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645Z for good quality output (200 dots per inch) amounts to 41.3 x 31 inch or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inch or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inch or 69.9 x 52.4 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 645Z, 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 645Z are ISO 100 to ISO 204800 (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 645Z offers substantially better image quality than the PEN-F (overall score 27 points higher). The advantage is based on 2.9 bits higher color depth, 2.3 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. 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 PEN-F provides a higher frame rate than the 645Z. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/60i.
Feature comparison: Olympus PEN-F vs Pentax 645Z
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 645Z 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 viewfinder in the PEN-F offers a wider field of view (100%) than the one in the 645Z (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 645Z has a higher magnification (0.78x vs 0.62x), 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 Olympus PEN-F, the Pentax 645Z, and comparable cameras.

One feature that differentiates the PEN-F and the 645Z is in-body image stabilization (IBIS). The PEN-F reduces the risk of handshake-induced blur with all attached lenses, while the 645Z has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.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 645Z 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 645Z 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 645Z write their files to SDXC cards. The 645Z 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 645Z can use UHS-I cards (up to 104 MB/s).
Connectivity comparison: Olympus PEN-F vs Pentax 645Z
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 645Z 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 645Z 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 645Z (unlike the PEN-F) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the PEN-F and the 645Z are recent models that are part of the current product line-up. The 645Z replaced the earlier Pentax 645D, while the PEN-F does not have a direct predecessor. 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 645Z
So what conclusions can be drawn? Which of the two cameras – the Olympus PEN-F or the Pentax 645Z – 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.

If the number of relative strengths (bullet points above) is taken as a guide, the PEN-F emerges as the winner of the contest (18 : 16 points). 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 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 PEN-F and the Pentax 645Z 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the PEN-F and the 645Z in practical situations. 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: Olympus PEN-F vs Pentax 645Z
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 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.
