Canon G1 X Mark II versus Olympus E-M10 III

The Canon PowerShot G1 X Mark II and the Olympus OM-D E-M10 Mark III are two digital cameras that were officially introduced, respectively, in February 2014 and August 2017. The G1X Mark II is a fixed lens compact, while the E-M10 III is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X Mark II) and a Four Thirds (E-M10 III) sensor. The Canon has a resolution of 13 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 II vs Olympus E-M10 III

The side-by-side display below illustrates the physical size and weight of the Canon G1 X Mark II and the Olympus E-M10 III. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the G1X Mark II – represents the basis or 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 (19 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the E-M10 III are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II 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 II gets 240 shots out of its NB-12L battery, while the E-M10 III can take 330 images on a single charge of its BLS-50 power pack.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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: Canon G1 X Mark II 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. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III is 14 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

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

Despite having a smaller sensor, the E-M10 III offers a higher resolution of 15.9 megapixel, compared with 13 MP of the G1X Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.49μm for the G1X Mark II). However, it should be noted that the E-M10 III is much more recent (by 3 years and 6 months) than the G1X Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M10 III provides a better video resolution than the G1X Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

 

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

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark II, the Olympus E-M10 III, and comparable cameras.

Both the G1X Mark II and the E-M10 III are recent models that feature in their makers' current product line-up. The G1X Mark II replaced the earlier Canon G1 X, while the E-M10 III followed on from the Olympus E-M10 II.

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

So how do things add up? Which of the two cameras – the Canon G1 X Mark II or the Olympus E-M10 III – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon PowerShot G1 X Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Ready to shoot: Has a lens build-in, whereas the E-M10 III requires a separate lens.
  • More compact: Is smaller (116x74mm vs 122x84mm) and thus needs less room in the bag.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been available for much longer (launched in February 2014).

ilogo

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

  • More detail: Has more megapixels (15.9 vs 13MP), which boosts linear resolution by 11%.
  • 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 1080/30p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (8.6 vs 5.2 flaps/sec) to capture the decisive moment.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (330 versus 240) out of a single battery charge.
  • More modern: Reflects 3 years and 6 months of technical progress since the G1X Mark II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 III emerges as the winner of the match-up (8 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

G1X Mark II 05:08 E-M10 III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G1X Mark II and the E-M10 III 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. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
