Panasonic G9 versus Fujifilm X100F

The Panasonic Lumix DC-G9 and the Fujifilm X100F are two enthusiast cameras that were announced, respectively, in November 2017 and January 2017. The G9 is a mirrorless interchangeable lens camera, while the X100F is a fixed lens compact. The cameras are based on a Four Thirds (G9) and an APS-C sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Fujifilm provides 24 MP.

Body comparison

The physical size and weight of the Panasonic G9 and the Fujifilm X100F are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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).

Body view (G9 on the left)

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X100F is notably smaller (28 percent) than the Panasonic G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the X100F does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100F has a lens build in, whereas the G9 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 G9 and their specifications in the Micro Four Thirds Lens Catalog.

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 X100F was launched at a lower price than the G9, 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

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Fujifilm X100F an APS-C sensor. The sensor area in the X100F is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the G9 has a native 4:3 aspect ratio, while the one in the X100F offers a 3:2 aspect.

Sensor size

With 24MP, the X100F offers a higher resolution than the G9 (20.2MP), but the X100F nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.34μm for the G9) due to its larger sensor. However, the G9 is a somewhat more recent model (by 9 months) than the X100F, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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.

Unlike the X100F, the G9 has the capacity to capture high quality composite images (80.6MP) 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).

Many modern cameras are not only capable of taking still images, but can also record movies. 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 X100F. It can shoot video footage at 4K/60p, while the Fujifilm is limited to 1080/60p.

Feature comparison

Beyond 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 X100F (3680k vs 2360k dots). The table below summarizes some of the other core capabilities of the Panasonic G9 and Fujifilm X100F in connection with corresponding information for a sample of similar cameras.

Both the G9 and the X100F are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X100F replaced the earlier Fujifilm X100T, while the G9 followed on from the Panasonic G85.

Summary

So what conclusions can be drawn? Which of the two cameras – the Panasonic G9 or the Fujifilm X100F – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Advantages of the Panasonic Lumix DC-G9:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • 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.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More modern: Is somewhat more recent (announced 9 months after the X100F).

Reasons to prefer the Fujifilm X100F:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Ready to shoot: Has an integrated lens, whereas the G9 necessitates an extra lens.
  • More compact: Is smaller (127x75mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the G9).
  • 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 January 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (12 : 8 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.

G9 12:08 X100F

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G9 and the X100F in practical situations. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
