Panasonic GX7 versus Olympus PEN-F
The Panasonic Lumix DMC-GX7 and the Olympus PEN-F are two enthusiast cameras that were officially introduced, respectively, in August 2013 and January 2016. Both the GX7 and the PEN-F are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Olympus provides 20.2 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: Panasonic GX7 vs Olympus PEN-F
The physical size and weight of the Panasonic GX7 and the Olympus PEN-F are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 – the GX7 – represents 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 somewhat larger (3 percent) than the Panasonic GX7. Moreover, the PEN-F is markedly heavier (6 percent) than the GX7. In this context, it is worth noting that neither the GX7 nor the PEN-F are weather-sealed.
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 camera comparisons there.

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 GX7 was launched at a somewhat lower price (by 17 percent) than the PEN-F, which makes it more attractive for photographers on a tight budget. 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: Panasonic GX7 vs Olympus PEN-F
The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to 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.
While the two cameras under review share the same sensor size, the PEN-F offers a higher resolution of 20.2 megapixel, compared with 15.8 MP of the GX7. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the PEN-F has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the GX7). However, it should be noted that the PEN-F is much more recent (by 2 years and 5 months) than the GX7, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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 GX7, 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).
For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the PEN-F has a markedly higher DXO score than the GX7 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.2 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.

The PEN-F is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX7 was succeeded by the Panasonic GX85.
Review summary: Panasonic GX7 vs Olympus PEN-F
So how do things add up? Is the Panasonic GX7 better than the Olympus PEN-F or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GX7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 2360k dots).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2013).
Advantages of the Olympus PEN-F:
- More detail: Has more megapixels (20.2 vs 15.8MP), which boosts linear resolution by 13%.
- 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 image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- More modern: Reflects 2 years and 5 months of technical progress since the GX7 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the PEN-F emerges as the winner of the match-up (7 : 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.
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 GX7 or the PEN-F. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
