Body comparison

The physical size and weight of the Fujifilm X100 and the Panasonic GH3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Fujifilm X100 vs Panasonic GH3
Compare X100 versus GH3 top
Comparison X100 or GH3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH3 is notably larger (31 percent) than the Fujifilm X100. It is noteworthy in this context that the GH3 is splash and dust-proof, 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 built in, whereas the GH3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GH3 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the X100 gets 300 shots out of its Fujifilm NP-95 battery, while the GH3 can take 540 images on a single charge of its Panasonic DMW-BLF19 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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 GH3, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Fujifilm X100 features an APS-C sensor and the Panasonic GH3 a Four Thirds sensor. The sensor area in the GH3 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X100 has a native 3:2 aspect ratio, while the one in the GH3 offers a 4:3 aspect.

Fujifilm X100 and Panasonic GH3 sensor measures

Despite having a smaller sensor, the GH3 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the X100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 5.53μm for the X100). However, it should be noted that the GH3 is a somewhat more recent model (by 1 year and 11 months) than the X100, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Panasonic GH3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH3 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Fujifilm X100 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Fujifilm FinePix X100 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Panasonic Lumix DMC-GH3 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

X100 versus GH3 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH3 has a touchscreen, while the X100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GH3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the X100 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GH3 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GH3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the X100 and the GH3 write their files to SDXC cards. The GH3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X100 cannot take advantage of Ultra High Speed SD cards.

It is notable that the GH3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X100 does not provide wifi capability.

Studio photographers will appreciate that the Panasonic GH3 (unlike the X100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X100 and the GH3 have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the GH3 was followed by the Panasonic GH4. Further information on the features and operation of the X100 and GH3 can be found, respectively, in the Fujifilm X100 Manual (free pdf) or the online Panasonic GH3 Manual.

Review summary

So what conclusions can be drawn? Is the Fujifilm X100 better than the Panasonic GH3 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Fujifilm FinePix X100:

  • Ready to shoot: Has a lens built-in, whereas the GH3 requires a separate lens.
  • More compact: Is smaller (126x75mm vs 133x93mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the GH3).
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in September 2010).

ilogo

Arguments in favor of the Panasonic Lumix DMC-GH3:

  • More detail: Has more megapixels (15.9 vs 12.2MP), which boosts linear resolution by 12%.
  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (1746k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.67x vs 0.50x).
  • 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 (614k vs 460k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (540 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the GH3 is the clear winner of the contest (21 : 5 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

X100 05:21 GH3

How about other alternatives? Do the specifications of the Fujifilm X100 and the Panasonic GH3 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the X100 or the GH3 perform in practice. 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
