Fujifilm X-A3 vs Panasonic G7
The Fujifilm X-A3 and the Panasonic Lumix DMC-G7 are two digital cameras that were announced, respectively, in August 2016 and May 2015. Both the X-A3 and the G7 are mirrorless interchangeable lens cameras that are based on an APS-C (X-A3) and a Four Thirds (G7) sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Panasonic provides 15.8 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-A3 and the Panasonic Lumix DMC-G7? 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.
The physical size and weight of the Fujifilm X-A3 and the Panasonic G7 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The X-A3 can be obtained in three different colors (silver, brown, pink), while the G7 is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G7 is notably larger (37 percent) than the Fujifilm X-A3. Moreover, the G7 is markedly heavier (21 percent) than the X-A3. In this context, it is worth noting that neither the X-A3 nor the G7 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-A3) and the Micro Four Thirds Lens Catalog (G7). 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-A3 gets 410 shots out of its NP-W126S battery, while the G7 can take 350 images on a single charge of its DMW-BLC12 power pack. The power pack in the X-A3 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch 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 39 percent) than the G7, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Fujifilm X-A3 features an APS-C sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 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-A3 has a native 3:2 aspect ratio, while the one in the G7 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24MP, the X-A3 offers a higher resolution than the G7 (15.8MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.77μm for the G7) due to its larger sensor. Moreover, the X-A3 is a somewhat more recent model (by 1 year and 3 months) than the G7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Fujifilm X-A3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic G7 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Fujifilm X-A3 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 DMC-G7 are ISO 160 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7 provides a better video resolution than the X-A3. 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 G7 has an electronic viewfinder (2360k 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 table below summarizes some of the other core capabilities of the Fujifilm X-A3 and Panasonic G7 in connection with corresponding information for a sample of similar cameras.
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 Fujifilm X-A3 and the Panasonic G7 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 X-A3 and the G7 write their files to SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X-A3 can use UHS-I cards (up to 104 MB/s).
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-A3 and Panasonic Lumix DMC-G7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X-A3 does not feature such a mic input.
Both the X-A3 and the G7 have been discontinued, but can regularly be found used on eBay. The G7 was replaced by the Panasonic G85, while the X-A3 was followed by the Fujifilm X-A5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Panasonic websites.
So what is the bottom line? Which of the two cameras – the Fujifilm X-A3 or the Panasonic G7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Fujifilm X-A3:
- More detail: Offers more megapixels (24 vs 15.8MP) with a 26% higher linear resolution.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- More compact: Is smaller (117x67mm vs 125x86mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 71g or 17 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (410 versus 350) on a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).

Reasons to prefer the Panasonic Lumix DMC-G7:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More heavily discounted: Has been on the market for longer (launched in May 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the X-A3 is the clear winner of the match-up (11 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

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 shooting experience and imaging performance when actually working with the X-A3 or the G7. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews 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], 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.

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
