Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M1 and the Sony Alpha A7C? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-M1 and the Sony A7C. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

Size Olympus E-M1 vs Sony A7C
Compare E-M1 versus A7C top
Comparison E-M1 or A7C rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7C is notably smaller (28 percent) than the Olympus E-M1. However, the A7C is slightly heavier (2 percent) than the E-M1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 (E-M1) and the Sony FE Lens Catalog (A7C). 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-M1 gets 350 shots out of its BLN-1 battery, while the A7C can take 740 images on a single charge of its NP-FZ100 power pack. The power pack in the A7C 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.

Notes: 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-M1 was launched at a somewhat lower price (by 22 percent) than the A7C, which makes it more attractive for photographers on a tight budget. 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

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M1 features a Four Thirds sensor and the Sony A7C a full frame sensor. The sensor area in the A7C is 276 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 E-M1 has a native 4:3 aspect ratio, while the one in the A7C offers a 3:2 aspect.

Olympus E-M1 and Sony A7C sensor measures

With 24MP, the A7C offers a higher resolution than the E-M1 (15.9MP), but the A7C nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the E-M1) due to its larger sensor. Moreover, the A7C is a much more recent model (by 7 years) than the E-M1, 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 the E-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7C implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7C for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-M1 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Olympus OM-D E-M1 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 Sony Alpha A7C are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

E-M1 versus A7C 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 A7C offers substantially better image quality than the E-M1 (overall score 22 points higher). The advantage is based on 2 bits higher color depth, 2 EV in additional dynamic range, and 2.2 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.

The A7C 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-M1 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, 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-M1 and the Sony A7C 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.

The E-M1 writes its imaging data to SDXC cards, while the A7C uses SDXC or Memory Stick PRO Duo cards. The A7C supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-M1 can use UHS-I cards (up to 104 MB/s).

It is notable that the A7C has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-M1 lacks such a headphone port.

Studio photographers will appreciate that the Olympus E-M1 (unlike the A7C) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7C is a recent model that features in the current product line-up of Sony. In contrast, the E-M1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M1 was succeeded by the Olympus E-M1 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 Sony websites.

  • More affordable: Was introduced into a lower priced segment (22 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2013).

ilogo

Arguments in favor of the Sony Alpha A7C:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (124x71mm vs 130x94mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (740 versus 350) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 7 years of technical progress since the E-M1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A7C is the clear winner of the contest (18 : 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-M1 07:18 A7C

How about other alternatives? Do the specifications of the Olympus E-M1 and the Sony A7C 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 says little about, for example, the shooting experience and imaging performance of the E-M1 and the A7C in practical situations. 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 expert reviews 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], 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
