Canon G1 X Mark II vs Olympus E-PM1
The Canon PowerShot G1 X Mark II and the Olympus PEN E-PM1 are two digital cameras that were revealed to the public, respectively, in February 2014 and June 2011. The G1X Mark II is a fixed lens compact, while the E-PM1 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X Mark II) and a Four Thirds (E-PM1) sensor. The Canon has a resolution of 13 megapixels, whereas the Olympus provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X Mark II and the Olympus PEN E-PM1? 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.
An illustration of the physical size and weight of the Canon G1 X Mark II and the Olympus E-PM1 is provided in the side-by-side display below. 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.
The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the G1X Mark II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM1 is notably smaller (18 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the E-PM1 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 built in, whereas the E-PM1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-PM1 and their specifications in the Micro Four Thirds Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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. 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.
The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 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.
With 13MP, the G1X Mark II offers a slightly higher resolution than the E-PM1 (12.2MP), but the G1X Mark II nevertheless has larger individual pixels (pixel pitch of 4.49μm versus 4.29μm for the E-PM1) due to its larger sensor. Moreover, the G1X Mark II is a much more recent model (by 2 years and 7 months) than the E-PM1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The Olympus PEN E-PM1 offers exactly the same ISO settings.
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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the G1X Mark II has a notably higher overall DXO score than the E-PM1 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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-PM1 provides a faster frame rate than the G1X Mark II. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The G1X Mark II and the E-PM1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the EVF-DC1 for the G1X Mark II and the VF-2 for the E-PM1 – are available as accessories. The table below summarizes some of the other core capabilities of the Canon G1 X Mark II and Olympus E-PM1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark II has one, while the E-PM1 does not. While the built-in flash of the G1X Mark II is not very powerful, it can at times be useful as a fill-in light.The G1X Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-PM1 does not have a selfie-screen.
The Canon G1 X Mark II has 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 G1X Mark II and the E-PM1 write their files to SDXC cards. The G1X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PM1 cannot take advantage of Ultra High Speed SD cards.
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 Canon PowerShot G1 X Mark II and Olympus PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark II offers wifi support, while the E-PM1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G1X Mark II and the E-PM1 have been discontinued, but can regularly be found used on ebay. The E-PM1 was replaced by the Olympus E-PM2, while the G1X Mark II was followed by the Canon G1 X Mark III. Further information on the features and operation of the G1X Mark II and E-PM1 can be found, respectively, in the Canon G1 X Mark II Manual (free pdf) or the online Olympus E-PM1 Manual.
So how do things add up? Is there a clear favorite between the Canon G1 X Mark II and the Olympus E-PM1? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot G1 X Mark II:
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has a lens built-in, whereas the E-PM1 requires a separate lens.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 7 months of technical progress since the E-PM1 launch.
Advantages of the Olympus PEN E-PM1:
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (110x64mm vs 116x74mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (330 versus 240) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in June 2011).
If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark II is the clear winner of the match-up (12 : 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. 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.
How about other alternatives? Do the specifications of the Canon G1 X Mark II and the Olympus E-PM1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X Mark II or the E-PM1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
