Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN-F and the Sony Alpha A7 IV? 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 PEN-F and the Sony A7 IV 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 width, height and depth measures are rounded to the nearest millimeter.

The PEN-F can be obtained in two different colors (black, silver), while the A7 IV is only available in black.

Size Olympus PEN-F vs Sony A7 IV
Compare PEN-F versus A7 IV top
Comparison PEN-F or A7 IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 IV is notably larger (40 percent) than the Olympus PEN-F. Moreover, the A7 IV is substantially heavier (54 percent) than the PEN-F. It is noteworthy in this context that the A7 IV 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (PEN-F) and the Sony FE Lens Catalog (A7 IV). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the PEN-F gets 330 shots out of its BLN-1 battery, while the A7 IV can take 580 images on a single charge of its NP-FZ100 power pack. The power pack in the A7 IV can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 PEN-F was launched at a markedly lower price (by 52 percent) than the A7 IV, which puts it into a different 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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.

Of the two cameras under consideration, the Olympus PEN-F features a Four Thirds sensor and the Sony A7 IV a full frame sensor. The sensor area in the A7 IV is 281 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 PEN-F has a native 4:3 aspect ratio, while the one in the A7 IV offers a 3:2 aspect.

Olympus PEN-F and Sony A7 IV sensor measures

With 32.7MP, the A7 IV offers a higher resolution than the PEN-F (20.2MP), but the A7 IV nevertheless has larger individual pixels (pixel pitch of 5.12μm versus 3.34μm for the PEN-F) due to its larger sensor. Moreover, the A7 IV is a much more recent model (by 5 years and 8 months) than the PEN-F, 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 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 Sony A7 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 IV for good quality output (200 dots per inch) amounts to 35 x 23.4 inches or 89 x 59.3 cm, for very good quality (250 dpi) 28 x 18.7 inches or 71.2 x 47.5 cm, and for excellent quality (300 dpi) 23.4 x 15.6 inches or 59.3 x 39.6 cm. The corresponding values for the Olympus PEN-F are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The A7 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the A7 IV, 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 Sony Alpha A7 IV are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the PEN-F is build around a CMOS sensor, while the A7 IV uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

PEN-F versus A7 IV MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A7 IV offers substantially better image quality than the PEN-F (overall score 23 points higher). The advantage is based on 2.3 bits higher color depth, 2.3 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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, both cameras under consideration feature an 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 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 PEN-F writes its imaging data to SDXC cards, while the A7 IV uses CFexpress (type A) or SDXC cards. The A7 IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the PEN-F only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 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-F and Sony Alpha A7 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 IV has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The PEN-F lacks such a headphone port.

The A7 IV is a recent model that features in the current product line-up of Sony. In contrast, the PEN-F has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the PEN-F from Olympus. Further information on the features and operation of the PEN-F and A7 IV can be found, respectively, in the Olympus PEN-F Manual (free pdf) or the online Sony A7 IV Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus PEN-F and the Sony A7 IV? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Olympus PEN-F:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (125x72mm vs 131x96mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 232g or 35 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (52 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in January 2016).

ilogo

Arguments in favor of the Sony Alpha A7 IV:

  • More detail: Has more megapixels (32.7 vs 20.2MP), which boosts linear resolution by 30%.
  • Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3686k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.62x).
  • Longer lasting: Gets more shots (580 versus 330) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 5 years and 8 months of technical progress since the PEN-F launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A7 IV is the clear winner of the contest (19 : 6 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.

PEN-F 06:19 A7 IV

How about other alternatives? Do the specifications of the Olympus PEN-F and the Sony A7 IV place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 remains incomplete and does no justice, for example, to the way the PEN-F or the A7 IV perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
