Fujifilm X-A1 vs Panasonic G100
The Fujifilm X-A1 and the Panasonic Lumix DC-G100 (labelled Panasonic G110 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2013 and June 2020. Both the X-A1 and the G100 are mirrorless interchangeable lens cameras that are based on an APS-C (X-A1) and a Four Thirds (G100) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Panasonic provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A1 and the Panasonic Lumix DC-G100? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
The physical size and weight of the Fujifilm X-A1 and the Panasonic G100 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.
The X-A1 can be obtained in two different colors (black, blue), while the G100 is only available in black.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G100 is notably larger (23 percent) than the Fujifilm X-A1. Moreover, the G100 is markedly heavier (7 percent) than the X-A1. In this context, it is worth noting that neither the X-A1 nor the G100 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-A1) and the Micro Four Thirds Lens Catalog (G100). 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.
Concerning battery life, the X-A1 gets 350 shots out of its Fujifilm NP-W126 battery, while the G100 can take 270 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the G100 can be charged via the USB port, which can be very convenient when travelling.

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 X-A1 was launched at a markedly lower price (by 39 percent) than the G100, which puts it into a different market segment. 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 X-A1 features an APS-C sensor and the Panasonic G100 a Four Thirds sensor. The sensor area in the G100 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 X-A1 has a native 3:2 aspect ratio, while the one in the G100 offers a 4:3 aspect.

Despite having a smaller sensor, the G100 offers a higher resolution of 20.2 megapixels, compared with 16 MP of the X-A1. 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 3.34μm versus 4.80μm for the X-A1). However, it should be noted that the G100 is much more recent (by 6 years and 9 months) than the X-A1, 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 the G100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic G100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G100 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Fujifilm X-A1 are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.
The Fujifilm X-A1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DC-G100 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the X-A1 is build around a CMOS sensor, while the G100 uses a Live MOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G100 provides a better video resolution than the X-A1. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G100 has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A1, the Panasonic G100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G100 has a touchscreen, while the X-A1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.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 G100 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 G100 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.
The X-A1 writes its imaging data to SDHC cards, while the G100 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm X-A1 and Panasonic Lumix DC-G100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G100 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-A1 lacks such a headphone port.
The G100 is a recent model that features in the current product line-up of Panasonic. In contrast, the X-A1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X-A1 was succeeded by the Fujifilm X-A2. Further information on the features and operation of the X-A1 and G100 can be found, respectively, in the Fujifilm X-A1 Manual (free pdf) or the online Panasonic G100 Manual.
Review summary
So how do things add up? Which of the two cameras – the Fujifilm X-A1 or the Panasonic G100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Fujifilm X-A1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- More compact: Is smaller (117x67mm vs 116x83mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (350 versus 270) on a single battery charge.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2013).

Reasons to prefer the Panasonic Lumix DC-G100:
- More detail: Has more megapixels (20.2 vs 16MP), which boosts linear resolution by 10%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- 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.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1840k vs 920k 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.
- Faster burst: Shoots at higher frequency (10 vs 5.6 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.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 6 years and 9 months of technical progress since the X-A1 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the G100 is the clear winner of the contest (15 : 6 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.
How about other alternatives? Do the specifications of the Fujifilm X-A1 and the Panasonic G100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X-A1 or the G100. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
