Canon G15 vs Olympus E-P5
The Canon PowerShot G15 and the Olympus PEN E-P5 are two digital cameras that were announced, respectively, in September 2012 and May 2013. The G15 is a fixed lens compact, while the E-P5 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (G15) and a Four Thirds (E-P5) sensor. The Canon has a resolution of 12 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 G15 and the Olympus PEN E-P5? 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 side-by-side display below illustrates the physical size and weight of the Canon G15 and the Olympus E-P5. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The E-P5 can be obtained in three different colors (black, silver, white), while the G15 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-P5 is somewhat larger (4 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the E-P5 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the E-P5 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-P5 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 want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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. The G15 was launched at a lower price than the E-P5, despite having a lens built in. 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 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G15 features a 1/1.7-inch sensor and the Olympus E-P5 a Four Thirds sensor. The sensor area in the E-P5 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 15.9MP, the E-P5 offers a higher resolution than the G15 (12MP), but the E-P5 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.89μm for the G15) due to its larger sensor. Moreover, the E-P5 is a somewhat more recent model (by 7 months) than the G15, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Olympus E-P5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P5 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 G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-P5 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the E-P5 offers substantially better image quality than the G15 (overall score 26 points higher). The advantage is based on 2.9 bits higher color depth, 0.9 EV in additional dynamic range, and 2.4 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-P5 provides a faster frame rate than the G15. It can shoot movie footage at 1080/30p, while the Canon is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G15 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P5 relies on live view and the rear LCD for framing. That said, the E-P5 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Canon G15 and Olympus E-P5 along with similar information for a selection of comparators.
|Olympus E-M5 II||2360||n||3.0||1037||swivel||Y||1/8000s||10.0||n||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-P5 has a touchscreen, while the G15 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Olympus E-P5 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 G15 and the E-P5 write their files to SDXC cards. The E-P5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G15 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 G15 and Olympus PEN E-P5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Olympus E-M5 II||Y||stereo||mono||Y||-||micro||2.0||Y||-||-|
It is notable that the E-P5 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G15 does not provide wifi capability.
Both the G15 and the E-P5 have been discontinued, but can regularly be found used on eBay. The G15 was replaced by the Canon G16, while the E-P5 does not have a direct successor. 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? Which of the two cameras – the Canon G15 or the Olympus E-P5 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the E-P5 is the clear winner of the contest (16 : 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 G15 and the Olympus E-P5 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G15 or the E-P5. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
