Panasonic G9 versus Fujifilm X-A3
The Panasonic Lumix DC-G9 and the Fujifilm X-A3 are two digital cameras that were officially introduced, respectively, in November 2017 and August 2016. Both the G9 and the X-A3 are mirrorless interchangeable lens cameras that 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.
The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Fujifilm X-A3. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth 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 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 X-A3 is considerably smaller (41 percent) than the Panasonic G9. Moreover, the X-A3 is substantially lighter (48 percent) than the G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the X-A3 does not feature any corresponding weather-sealing.
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 find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (G9) and the Fujinon X Lens Catalog (X-A3). 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.
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 X-A3 was launched at a markedly lower price (by 77 percent) than the G9, which puts it into a different market segment. 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 X-A3 an APS-C sensor. The sensor area in the X-A3 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 X-A3 offers a 3:2 aspect.
With 24MP, the X-A3 offers a higher resolution than the G9 (20.2MP), but the X-A3 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 1 year and 2 months) than the X-A3, 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 the G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the X-A3, 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).
For most cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. 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 X-A3. It can shoot video footage at 4K/60p, while the Fujifilm is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G9 has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A3 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic G9 and Fujifilm X-A3 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G9 and the X-A3 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-A3 replaced the earlier Fujifilm X-A2, while the G9 followed on from the Panasonic G85.
So how do things add up? Is there a clear favorite between the Panasonic G9 and the Panasonic G9? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DC-G9:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- 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.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (20 vs 6 flaps/sec) to capture the decisive moment.
- 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 1 year and 2 months after the X-A3).
Arguments in favor of the Fujifilm X-A3:
- More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- More compact: Is smaller (117x67mm vs 137x97mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 319g or 48 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the G9 emerges as the winner of the contest (11 : 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G9 and the X-A3 in practical situations. 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. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
In case you would like to check on the differences and similarities of other camera models, just make your choice using the following search menu. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If the camera you are interested in is not available, please contact me, and I will try to add information on that model to the database.
