Panasonic G9 versus Fujifilm X100

The Panasonic Lumix DC-G9 and the Fujifilm FinePix X100 are two enthusiast cameras that were revealed to the public, respectively, in November 2017 and September 2010. The G9 is a mirrorless interchangeable lens camera, while the X100 is a fixed lens compact. The cameras are based on a Four Thirds (G9) and an APS-C (X100) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Fujifilm provides 12.2 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 G9 vs Fujifilm X100

The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Fujifilm X100. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage 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 Fujifilm X100 is notably smaller (29 percent) than the Panasonic G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the X100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100 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.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the X100 can take 300 images on a single charge of its NP-95 power pack.

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 X100 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: Panasonic G9 vs Fujifilm X100

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Fujifilm X100 an APS-C sensor. The sensor area in the X100 is 66 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 X100 offers a 3:2 aspect.

Panasonic G9 and Fujifilm X100 sensor measures

Despite having a smaller sensor, the Panasonic G9 offers a higher resolution of 20.2 megapixel, compared with 12.2 MP of the Fujifilm X100. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 5.53μm for the X100). However, it should be noted that the G9 is much more recent (by 7 years and 1 month) than the X100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 X100, 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).

G9 versus X100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

The G9 is a current model that online retailers, such as amazon, will have in stock. In contrast, the X100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the X100 was succeeded by the Fujifilm X100S.

Review summary: Panasonic G9 vs Fujifilm X100

So what is the bottom line? Which of the two cameras – the Panasonic G9 or the Fujifilm X100 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Panasonic Lumix DC-G9:

  • More detail: Offers more megapixels (20.2 vs 12.2MP) with a 26% higher linear resolution.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/60p vs 720/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 1440k dots).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • 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 5 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 (400 versus 300) on a single battery charge.
  • 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: Reflects 7 years and 1 month of technical progress since the X100 launch.

ilogo

Arguments in favor of the Fujifilm FinePix X100:

  • Ready to shoot: Has an integrated lens, whereas the G9 necessitates an extra lens.
  • More compact: Is smaller (126x75mm 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 around for much longer (launched in September 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (16 : 6 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 when reflecting and deciding on a new camera.

G9 16:06 X100

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9 or the X100. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
