Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-P1 and the Panasonic Lumix DC-GH5s? 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 E-P1 vs Panasonic GH5s

The physical size and weight of the Olympus E-P1 and the Panasonic GH5s 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 dimensions are rounded to the nearest millimeter.

The E-P1 can be obtained in three different colors (black, silver, white), while the GH5s is only available in black.

Compare E-P1 versus GH5s top
Comparison E-P1 or GH5s rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH5s is considerably larger (61 percent) than the Olympus E-P1. Moreover, the GH5s is substantially heavier (86 percent) than the E-P1. It is noteworthy in this context that the GH5s is splash and dust-proof, while the E-P1 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. 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 E-P1 gets 300 shots out of its BLS-1 battery, while the GH5s can take 440 images on a single charge of its DMW-BLF19 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Note: Measurements and pricing do not include easily detachable parts, such as 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 E-P1 was launched at a markedly lower price (by 68 percent) than the GH5s, 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: Olympus E-P1 vs Panasonic GH5s

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. 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.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Olympus E-P1 and Panasonic GH5s sensor measures

While the two cameras under review share the same sensor size, the E-P1 offers a higher resolution of 12.2 megapixels, compared with 9.9 MP of the GH5s. This megapixels advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-P1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.77μm for the GH5s). Moreover, it should be noted that the GH5s is much more recent (by 8 years and 6 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the GH5s has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus E-P1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P1 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inch or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inch or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inch or 34.1 x 25.6 cm. The corresponding values for the Panasonic GH5s are 18.4 x 13.5 inch or 46.7 x 34.3 cm for good quality, 14.7 x 10.8 inch or 37.4 x 27.4 cm for very good quality, and 12.3 x 9 inch or 31.2 x 22.9 cm for excellent quality prints.

The Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DC-GH5s are ISO 160 to ISO 51200, with the possibility to increase the ISO range to 80-204800.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GH5s provides a better video resolution than the E-P1. It can shoot movie footage at 4K/60p, while the Olympus is limited to 720/30p.

 

Feature comparison: Olympus E-P1 vs Panasonic GH5s

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH5s has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Olympus E-P1, the Panasonic GH5s, and comparable cameras.

One feature that differentiates the E-P1 and the GH5s is in-body image stabilization (IBIS). The E-P1 reduces the risk of handshake-induced blur with all attached lenses, while the GH5s has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The GH5s has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-P1 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 GH5s 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 Panasonic GH5s 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 E-P1 writes its imaging data to SDHC cards, while the GH5s uses SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P1 only has one slot. The GH5s supports UHS-II cards (on both slots), while the E-P1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus E-P1 vs Panasonic GH5s

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-P1 and Panasonic Lumix DC-GH5s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH5s offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P1 does not offer wifi capability.

Studio photographers will appreciate that the Panasonic GH5s (unlike the E-P1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The GH5s is a recent model that features in the current product line-up of Panasonic. In contrast, the E-P1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-P1 was succeeded by the Olympus E-P2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.


Review summary: Olympus E-P1 vs Panasonic GH5s

So what conclusions can be drawn? Which of the two cameras – the Olympus E-P1 or the Panasonic GH5s – 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.

ilogo

Arguments in favor of the Olympus PEN E-P1:

  • More detail: Offers more megapixels (12.2 vs 9.9MP) with a 10% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (121x70mm vs 139x98mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 305g or 46 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in June 2009).

ilogo

Reasons to prefer the Panasonic Lumix DC-GH5s:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/60p vs 720/30p).
  • 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.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 230k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (440 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards on both slots.
  • More modern: Reflects 8 years and 6 months of technical progress since the E-P1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GH5s is the clear winner of the contest (24 : 7 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.

E-P1 07:24 GH5s

How about other alternatives? Do the specifications of the Olympus E-P1 and the Panasonic GH5s 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-P1 or the GH5s perform in practice. 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 E-P1 vs Panasonic GH5s

This is where reviews by experts come in. 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 above review scores should be interpreted 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
