Olympus PEN-F versus Canon G5 X

The Olympus PEN-F and the Canon PowerShot G5 X are two digital cameras that were revealed to the public, respectively, in January 2016 and October 2015. The PEN-F is a mirrorless interchangeable lens camera, while the G5X is a fixed lens compact. The cameras are based on a Four Thirds (PEN-F) and an one-inch (G5X) sensor. The Olympus has a resolution of 20.2 megapixel, whereas the Canon provides 20 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: Olympus PEN-F vs Canon G5 X

The physical size and weight of the Olympus PEN-F and the Canon G5 X are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions 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 side – the PEN-F – represents the basis for the calculations 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 Canon G5 X is notably smaller (5 percent) than the Olympus PEN-F. In this context, it is worth noting that neither the PEN-F nor the G5X are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G5X has a lens build in, whereas the PEN-F 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 PEN-F and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the PEN-F gets 330 shots out of its BLN-1 battery, while the G5X can take 210 images on a single charge of its NB-13L power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. The G5X was launched at a lower price than the PEN-F, despite having a lens build 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus PEN-F vs Canon G5 X

The size of the imaging sensor is a crucial determinant 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 Olympus PEN-F features a Four Thirds sensor and the Canon G5 X an one-inch sensor. The sensor area in the G5X is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the PEN-F has a native 4:3 aspect ratio, while the one in the G5X offers a 3:2 aspect.

Olympus PEN-F and Canon G5 X sensor measures

With 20.2MP, the PEN-F offers a slightly higher resolution than the G5X (20MP), but the PEN-F nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the PEN-F is a somewhat more recent model (by 3 months) than the G5X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the PEN-F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the G5X, the PEN-F has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

PEN-F versus G5X MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Olympus PEN-F vs Canon G5 X

Beyond body and sensor, cameras can and do differ across a range of features. The PEN-F and the G5X are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The following table reports on some other key feature differences and similarities of the Olympus PEN-F, the Canon G5 X, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the PEN-F and the G5X are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Olympus and Canon.

Review summary: Olympus PEN-F vs Canon G5 X

So how do things add up? Which of the two cameras – the Olympus PEN-F or the Canon G5 X – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus PEN-F:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (330 versus 210) on a single battery charge.
  • More modern: Is somewhat more recent (announced 3 months after the G5X).

ilogo

Reasons to prefer the Canon PowerShot G5 X:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Ready to shoot: Has an integrated lens, whereas the PEN-F necessitates an extra lens.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the PEN-F).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the PEN-F emerges as the winner of the contest (8 : 6 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.

PEN-F 08:06 G5X

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the PEN-F or the G5X. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
