Panasonic G9 versus Olympus PEN-F
The Panasonic Lumix DC-G9 and the Olympus PEN-F are two enthusiast cameras that were officially introduced, respectively, in November 2017 and January 2016. Both the G9 and the PEN-F are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 20.2 megapixel.
An illustration of the physical size and weight of the Panasonic G9 and the Olympus PEN-F is provided 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 toggle the display 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 – the G9 – represents the basis or 100 percent 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 Olympus PEN-F is notably smaller (32 percent) than the Panasonic G9. Moreover, the PEN-F is substantially lighter (35 percent) than the G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the PEN-F does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The PEN-F was launched at a markedly lower price (by 29 percent) than the G9, which puts it into a different market segment. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixel. This similarity in sensor specs implies that both the G9 and the PEN-F have the same pixel density, as well as the same pixel size. It should, however, be noted that the G9 is a somewhat more recent model (by 1 year and 9 months) than the PEN-F, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 G9 provides a higher video resolution than the PEN-F. It can shoot video footage at 4K/60p, while the Olympus is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the G9 offers a substantially higher resolution than the one in the PEN-F (3680k vs 2360k dots). The adjacent table lists some of the other core features of the Panasonic G9 and Olympus PEN-F along with similar information for a selection of comparators.

Both the G9 and the PEN-F are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G9 replaced the earlier Panasonic G85, while the PEN-F does not have a direct predecessor.
So what is the bottom line? Which of the two cameras – the Panasonic G9 or the Olympus PEN-F – has the upper hand? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DC-G9:
- Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2360k dots).
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Faster burst: Shoots at higher frequency (20 vs 10 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (400 versus 330) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More modern: Is somewhat more recent (announced 1 year and 9 months after the PEN-F).
Arguments in favor of the Olympus PEN-F:
- More compact: Is smaller (125x72mm vs 137x97mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 231g or 35 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in January 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the G9 emerges as the winner of the contest (7 : 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.
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 handling experience and imaging performance when actually working with the G9 or the PEN-F. 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 rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted 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 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.
