Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX800 and the Fujifilm X-A10? 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 Panasonic GX800 and the Fujifilm X-A10 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The GX800 can be obtained in three different colors (black, silver, red), while the X-A10 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 Fujifilm X-A10 is notably larger (13 percent) than the Panasonic GX800. Moreover, the X-A10 is markedly heavier (23 percent) than the GX800. In this context, it is worth noting that neither the GX800 nor the X-A10 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 Micro Four Thirds Lens Catalog (GX800) and the Fujinon X Lens Catalog (X-A10). 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 GX800 gets 210 shots out of its Panasonic DMW-BLH7 battery, while the X-A10 can take 410 images on a single charge of its Fujifilm NP-W126S power pack. The power pack in the X-A10 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X-A10 was launched at a markedly lower price (by 27 percent) than the GX800, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 GX800 features a Four Thirds sensor and the Fujifilm X-A10 an APS-C sensor. The sensor area in the X-A10 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 GX800 has a native 4:3 aspect ratio, while the one in the X-A10 offers a 3:2 aspect.

With 16MP, the X-A10 offers a higher resolution than the GX800 (15.8MP), but the X-A10 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.77μm for the GX800) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Panasonic Lumix DMC-GX800 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Fujifilm X-A10 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 GX800 provides a higher video resolution than the X-A10. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The GX800 and the X-A10 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Panasonic GX800 and Fujifilm X-A10 along with similar information for a selection of comparators.

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 GX800 has a touchscreen, while the X-A10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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, both cameras under consideration feature an 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 GX800 and the Fujifilm X-A10 both have 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 GX800 and the X-A10 write their files to 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 Panasonic Lumix DMC-GX800 and Fujifilm X-A10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GX800 and the X-A10 have been discontinued, but can regularly be found used on ebay. The X-A10 was replaced by the Fujifilm X-A5, while the GX800 does not have a direct successor. Further information on the features and operation of the GX800 and X-A10 can be found, respectively, in the Panasonic GX800 Manual (free pdf) or the online Fujifilm X-A10 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX800 and the Fujifilm X-A10? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Panasonic Lumix DMC-GX800:

• 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).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (107x65mm vs 117x67mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 62g or 19 percent) and hence easier to carry around.

Advantages of the Fujifilm X-A10:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
• Longer lasting: Gets more shots (410 versus 210) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).

If the number of relative strengths (bullet points above) is taken as a guide, the X-A10 emerges as the winner of the match-up (9 : 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Panasonic GX800 and the Fujifilm X-A10 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the GX800 and the X-A10 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
