Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark IV and the Sony Alpha A6100? 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

An illustration of the physical size and weight of the Olympus E-M10 IV and the Sony A6100 is provided 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-M10 IV can be obtained in two different colors (black, silver), while the A6100 is available in three color-versions (black, silver, white).

Compare E-M10 IV versus A6100 top
Comparison E-M10 IV or A6100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6100 is notably smaller (22 percent) than the Olympus E-M10 IV. However, the A6100 is slightly heavier (3 percent) than the E-M10 IV. In this context, it is worth noting that neither the E-M10 IV nor the A6100 are weather-sealed.

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-M10 IV) and the Sony E-Mount Lens Catalog (A6100). 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-M10 IV gets 360 shots out of its BLS-50 battery, while the A6100 can take 420 images on a single charge of its NP-FW50 power pack. The battery packs of both cameras can be charged via USB, 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 E-M10 IV was somewhat cheaper (by 7 percent) than the A6100 at launch, but both cameras fall into the same price category. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M10 IV features a Four Thirds sensor and the Sony A6100 an APS-C sensor. The sensor area in the A6100 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-M10 IV has a native 4:3 aspect ratio, while the one in the A6100 offers a 3:2 aspect.

Olympus E-M10 IV and Sony A6100 sensor measures

With 24MP, the A6100 offers a higher resolution than the E-M10 IV (20.2MP), but the A6100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the E-M10 IV) due to its larger sensor. However, the E-M10 IV is a somewhat more recent model (by 11 months) than the A6100, 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 the E-M10 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A6100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6100 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-M10 IV 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 A6100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus OM-D E-M10 Mark IV 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 A6100 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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

One feature that differentiates the E-M10 IV and the A6100 is in-body image stabilization (IBIS). The E-M10 IV reduces the risk of handshake-induced blur with all attached lenses, while the A6100 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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-M10 IV and the Sony A6100 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-M10 IV writes its imaging data to SDXC cards, while the A6100 uses SDXC or Memory Stick PRO Duo cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A6100 can use UHS-I cards (up to 104 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 OM-D E-M10 Mark IV and Sony Alpha A6100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6100 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 IV does not feature such a mic input.

The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the A6100 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A6100 was succeeded by the Sony A6600. Further information on the features and operation of the E-M10 IV and A6100 can be found, respectively, in the Olympus E-M10 IV Manual (free pdf) or the online Sony A6100 Manual.

Review summary

So what is the bottom line? Is the Olympus E-M10 IV better than the Sony A6100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus OM-D E-M10 Mark IV:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • Faster burst: Shoots at higher frequency (15 vs 11 flaps/sec) to capture the decisive moment.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Is somewhat more recent (announced 11 months after the A6100).

ilogo

Advantages of the Sony Alpha A6100:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • 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.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.62x).
  • More compact: Is smaller (120x67mm vs 122x84mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (420 versus 360) out of a single battery charge.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in August 2019).

If the count of individual advantages (bullet points above) is taken as a guide, the A6100 is the clear winner of the contest (13 : 7 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 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.

E-M10 IV 07:13 A6100

How about other alternatives? Do the specifications of the Olympus E-M10 IV and the Sony A6100 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-M10 IV or the A6100 perform in practice. 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 following table reports the overall ratings of the cameras as published by some of the major 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
