Canon G1 X vs Olympus E-P1
The Canon PowerShot G1 X and the Olympus PEN E-P1 are two enthusiast cameras that were revealed to the public, respectively, in January 2012 and June 2009. The G1X is a fixed lens compact, while the E-P1 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X) and a Four Thirds (E-P1) sensor. The Canon has a resolution of 14.2 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 and the Olympus PEN E-P1? 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 and the Olympus E-P1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The E-P1 can be obtained in three different colors (black, silver, white), while the G1X 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-P1 is notably smaller (11 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the E-P1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the E-P1 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-P1 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. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 features an 1.5-inch sensor and the Olympus E-P1 a Four Thirds sensor. The sensor area in the E-P1 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 14.2MP, the G1X offers a higher resolution than the E-P1 (12.2MP), but the G1X nevertheless has marginally larger individual pixels (pixel pitch of 4.30μm versus 4.29μm for the E-P1) due to its larger sensor. Moreover, the G1X is a much more recent model (by 2 years and 6 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon G1 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X for good quality output (200 dots per inch) amounts to 21.8 x 16.3 inches or 55.3 x 41.5 cm, for very good quality (250 dpi) 17.4 x 13.1 inches or 44.2 x 33.2 cm, and for excellent quality (300 dpi) 14.5 x 10.9 inches or 36.8 x 27.6 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Canon PowerShot G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (no boost).
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 review, the G1X has a notably higher overall DXO score than the E-P1 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.4 EV in additional dynamic range, and 0.3 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G1X provides a higher video resolution than the E-P1. It can shoot video footage at 1080/24p, while the Olympus is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G1 X and Olympus E-P1 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 has one, while the E-P1 does not. While the built-in flash of the G1X is not very powerful, it can at times be useful as a fill-in light.The G1X 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-P1 does not have a selfie-screen.
The G1X writes its imaging data to SDXC cards, while the E-P1 uses SDHC 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 and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G1X and the E-P1 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the G1X was followed by the Canon G1X Mark II. 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 how do things add up? Is there a clear favorite between the Canon G1 X and the Olympus E-P1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G1 X:
- More detail: Offers more megapixels (14.2 vs 12.2MP) with a 8% higher linear resolution.
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- Better video: Provides higher definition movie capture (1080/24p vs 720/30p).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Ready to shoot: Has a lens built-in, whereas the E-P1 requires a separate lens.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More modern: Reflects 2 years and 6 months of technical progress since the E-P1 launch.
Reasons to prefer the Olympus PEN E-P1:
- Faster burst: Shoots at higher frequency (3 vs 1.9 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (121x70mm vs 117x81mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (300 versus 250) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in June 2009).
If the count of relative strengths (bullet points above) is taken as a measure, the G1X is the clear winner of the match-up (9 : 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 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 and the Olympus E-P1 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 says little about, for example, the shooting experience and imaging performance of the G1X and the E-P1 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 above review scores should be interpreted 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.
