Body comparison

The physical size and weight of the Olympus E-P7 and the OM System OM-1 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-P7 can be obtained in three different colors (black, silver, white), while the OM-1 is only available in black.

Size Olympus E-P7 vs OM System OM-1
Compare E-P7 versus OM-1 top
Comparison E-P7 or OM-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the OM System OM-1 is considerably larger (53 percent) than the Olympus E-P7. Moreover, the OM-1 is substantially heavier (78 percent) than the E-P7. It is noteworthy in this context that the OM-1 is splash and dust-proof, while the E-P7 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-P7 gets 360 shots out of its Olympus BLS-50 battery, while the OM-1 can take 520 images on a single charge of its OM System BLX-1 power pack. The power pack in the OM-1 can be charged via the USB port, which can be very convenient when travelling.

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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 E-P7 was launched at a markedly lower price (by 64 percent) than the OM-1, 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

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 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a Four Thirds sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the OM-1 uses a more advanced image processing engine (TruePic X) than the E-P7 (TruePic VIII), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-P7 and OM System OM-1 sensor measures

Even though the E-P7 has a slightly larger sensor, both cameras offer the same resolution of 20.2 megapixels. This implies that the E-P7 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.34μm versus 3.34μm for the OM-1), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the OM-1 is a somewhat more recent model (by 8 months) than the E-P7, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the OM-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The OM-1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the E-P7, the OM-1 has the capacity to capture high quality composite images (80MP) 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-P7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the OM System OM-1 are ISO 80 to ISO 25600, with the possibility to increase the ISO range to 80-102400.

In terms of underlying technology, the E-P7 is build around a CMOS sensor, while the OM-1 uses a Stacked 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.

E-P7 versus OM-1 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the OM-1 provides a faster frame rate than the E-P7. It can shoot movie footage at 4K/60p, while the Olympus is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the OM-1 has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P7 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-P7 and OM System OM-1 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The E-P7 has one, while the OM-1 does not. While the built-in flash of the E-P7 is not very powerful, it can at times be useful as a fill-in light.

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 E-P7 and the OM System OM-1 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 E-P7 and the OM-1 write their files to SDXC cards. The OM-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P7 only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s).

It is notable that the OM-1 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-P7 lacks such a headphone port.

Studio photographers will appreciate that the OM System OM-1 (unlike the E-P7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The E-P7 is a recent model that features in the current product line-up of Olympus. In contrast, the OM-1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the OM-1 was succeeded by the OM System OM-1 II. Further information on the features and operation of the E-P7 and OM-1 can be found, respectively, in the Olympus E-P7 Manual (free pdf) or the online OM System OM-1 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-P7 and the OM System OM-1? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Olympus PEN E-P7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (118x69mm vs 135x92mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 262g or 44 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2021).

ilogo

Advantages of the OM System OM-1:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better jpgs: Has a more modern image processing engine (TruePic X vs TruePic VIII).
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • 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.
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1640k vs 1040k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 8.7 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (520 versus 360) 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 (3.0 vs 2.0).
  • 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.
  • More modern: Was introduced somewhat (8 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the OM-1 is the clear winner of the contest (19 : 6 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-P7 06:19 OM-1

How about other alternatives? Do the specifications of the Olympus E-P7 and the OM System OM-1 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 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 E-P7 and the OM-1 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

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. 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.
