Fujifilm X100S versus Panasonic GX850
The Fujifilm X100S and the Panasonic Lumix DMC-GX850 (labelled Panasonic GX800 in some countries) are two digital cameras that were revealed to the public, respectively, in January 2013 and January 2017. The X100S is a fixed lens compact, while the GX850 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (X100S) and a Four Thirds sensor. The Fujifilm has a resolution of 16 megapixel, whereas the Panasonic provides 15.8 MP.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X100S and the Panasonic GX850. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 side – the X100S – represents the basis for the calculations 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 Panasonic GX850 is notably smaller (26 percent) than the Fujifilm X100S. In this context, it is worth noting that neither the X100S nor the GX850 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100S has a lens build in, whereas the GX850 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 GX850 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. 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 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 Fujifilm X100S features an APS-C sensor and the Panasonic GX850 a Four Thirds sensor. The sensor area in the GX850 is 39 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 X100S has a native 3:2 aspect ratio, while the one in the GX850 offers a 4:3 aspect.
With 16MP, the X100S offers a slightly higher resolution than the GX850 (15.8MP), but the X100S nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.77μm for the GX850) due to its larger sensor. However, the GX850 is a somewhat more recent model (by 3 years and 11 months) than the X100S, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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.
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.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX850 provides a better video resolution than the X100S. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X100S has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX850 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X100S and Panasonic GX850 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The GX850 is a current model that online retailers, such as amazon, will have in stock. In contrast, the X100S has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the X100S was succeeded by the Fujifilm X100T.
So what is the bottom line? Which of the two cameras – the Fujifilm X100S or the Panasonic GX850 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Fujifilm X100S:
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
- Ready to shoot: Has a lens build-in, whereas the GX850 requires a separate lens.
- Longer lasting: Can take more shots (330 versus 210) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in January 2013).
Reasons to prefer the Panasonic Lumix DMC-GX850:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- 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 a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (107x65mm vs 127x74mm) and will fit more readily into a bag.
- More modern: Reflects 3 years and 11 months of technical progress since the X100S launch.
If the count of individual advantages (bullet points above) is taken as a guide, the GX850 is the clear winner of the contest (9 : 5 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 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 X100S or the GX850. 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. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you cannot find the camera you are interested in, please send me an email, and I will try to add information on that model to the database.
