Canon G1 X Mark III versus Olympus E-M10 III

The Canon PowerShot G1 X Mark III and the Olympus OM-D E-M10 Mark III are two digital cameras that were officially introduced, respectively, in October 2017 and August 2017. The G1X Mark III is a fixed lens compact, while the E-M10 III is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (G1X Mark III) and a Four Thirds (E-M10 III) sensor. The Canon has a resolution of 24 megapixel, whereas the Olympus provides 15.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon G1 X Mark III vs Olympus E-M10 III

The side-by-side display below illustrates the physical size and weight of the Canon G1 X Mark III and the Olympus E-M10 III. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the G1X Mark III – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 III is notably larger (14 percent) than the Canon G1 X Mark III. It is worth mentioning in this context that the G1X Mark III is splash and dust resistant, while the E-M10 III does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build in, whereas the E-M10 III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G1X Mark III gets 200 shots out of its NB-13L battery, while the E-M10 III can take 330 images on a single charge of its BLS-50 power pack.

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. 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: Canon G1 X Mark III vs Olympus E-M10 III

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the G1X Mark III has a native 3:2 aspect ratio, while the one in the E-M10 III offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon G1 X Mark III and Olympus E-M10 III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the E-M10 III (15.9MP), but the G1X Mark III has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.76μm for the E-M10 III). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M10 III provides a better video resolution than the G1X Mark III. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Canon G1 X Mark III vs Olympus E-M10 III

Apart from body and sensor, cameras can and do differ across a variety of features. The G1X Mark III and the E-M10 III are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark III, the Olympus E-M10 III, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Canon G1 X Mark III vs Olympus E-M10 III

So what conclusions can be drawn? Which of the two cameras – the Canon G1 X Mark III or the Olympus E-M10 III – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon PowerShot G1 X Mark III:

  • More detail: Offers more megapixels (24 vs 15.9MP) with a 25% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Ready to shoot: Has a lens build-in, whereas the E-M10 III requires a separate lens.
  • More compact: Is smaller (115x78mm vs 122x84mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the E-M10 III).
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.

ilogo

Reasons to prefer the Olympus OM-D E-M10 Mark III:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (330 versus 200) out of a single battery charge.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III emerges as the winner of the contest (7 : 5 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.

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 G1X Mark III or the E-M10 III handle or 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. This is why expert reviews are important.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
