Canon G1 X Mark II vs Olympus E-PL7
The Canon PowerShot G1 X Mark II and the Olympus PEN E-PL7 are two digital cameras that were revealed to the public, respectively, in February 2014 and August 2014. The G1X Mark II is a fixed lens compact, while the E-PL7 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X Mark II) and a Four Thirds (E-PL7) sensor. The Canon has a resolution of 13 megapixels, whereas the Olympus provides 15.9 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-PL7? 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.
The physical size and weight of the Canon G1 X Mark II and the Olympus E-PL7 are illustrated 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-PL7 can be obtained in two different colors (black, silver), 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-PL7 is notably smaller (10 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the E-PL7 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-PL7 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-PL7 and their specifications in the Micro Four Thirds Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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.
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 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-PL7 a Four Thirds sensor. The sensor area in the E-PL7 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.
Despite having a smaller sensor, the E-PL7 offers a higher resolution of 15.9 megapixels, compared with 13 MP of the G1X Mark II. This megapixels 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-PL7 is a somewhat more recent model (by 6 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The resolution advantage of the Olympus E-PL7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL7 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Canon G1 X Mark II are 20.8 x 15.6 inches or 52.8 x 39.6 cm for good quality, 16.6 x 12.5 inches or 42.3 x 31.7 cm for very good quality, and 13.9 x 10.4 inches or 35.2 x 26.4 cm for excellent quality prints.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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.
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. Of the two cameras under consideration, the E-PL7 offers substantially better image quality than the G1X Mark II (overall score 14 points higher). The advantage is based on 1.2 bits higher color depth, 1.6 EV in additional dynamic range, and 0.6 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 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, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The G1X Mark II and the E-PL7 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-4 for the E-PL7 – are available as accessories. The table below summarizes some of the other core capabilities of the Canon G1 X Mark II and Olympus E-PL7 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-PL7 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.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 Canon G1 X Mark II and the Olympus E-PL7 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.
Concerning the storage of imaging data, both the G1X Mark II and the E-PL7 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G1X Mark II and the E-PL7 have been discontinued, but can regularly be found used on ebay. The G1X Mark II was replaced by the Canon G1 X Mark III, while the E-PL7 was followed by the Olympus E-PL8. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So what conclusions can be drawn? Is the Canon G1 X Mark II better than the Olympus E-PL7 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot G1 X Mark II:
- Ready to shoot: Has a lens built-in, whereas the E-PL7 requires a separate lens.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- 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 February 2014).
Advantages of the Olympus PEN E-PL7:
- More detail: Has more megapixels (15.9 vs 13MP), which boosts linear resolution by 11%.
- Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
- Faster burst: Shoots at higher frequency (8 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 (350 versus 240) out of a single battery charge.
- More modern: Was introduced somewhat (6 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the E-PL7 is the clear winner of the contest (9 : 4 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.
How about other alternatives? Do the specifications of the Canon G1 X Mark II and the Olympus E-PL7 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 the spec-sheets of cameras can offer a general idea of their imaging potential, 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-PL7. 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 hands-on reviews by experts 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], 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
