Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A7 and the Panasonic Lumix DC-S1H? 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

An illustration of the physical size and weight of the Fujifilm X-A7 and the Panasonic S1H is provided 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 X-A7 can be obtained in four different colors (silver, graphite, brown, green), while the S1H 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 S1H is considerably larger (113 percent) than the Fujifilm X-A7. Moreover, the S1H is substantially heavier (229 percent) than the X-A7. It is noteworthy in this context that the S1H is splash and dust-proof, while the X-A7 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the X-A7 gets 440 shots out of its Fujifilm NP-W126S battery, while the S1H can take 400 images on a single charge of its Panasonic DMW-BLJ31 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-A7 was launched at a markedly lower price (by 88 percent) than the S1H, 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. 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. 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 X-A7 features an APS-C sensor and the Panasonic S1H a full frame sensor. The sensor area in the S1H is 130 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the S1H has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the S1H has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.92μm for the X-A7), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the X-A7 is a somewhat more recent model (by 3 months) than the S1H, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The X-A7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the X-A7, the S1H has the capacity to capture high quality composite images (96MP) 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).

The Fujifilm X-A7 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Panasonic Lumix DC-S1H are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

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 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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the S1H provides a better video resolution than the X-A7. It can shoot movie footage at 6K/30p, while the Fujifilm is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the S1H has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A7 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X-A7 and Panasonic S1H 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 difference between the cameras concerns the presence of an on-board flash. The X-A7 has one, while the S1H does not. While the built-in flash of the X-A7 is not very powerful, it can at times be useful as a fill-in light.

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-A7 and the Panasonic S1H 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-A7 and the S1H write their files to SDXC cards. The S1H features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A7 only has one slot. The S1H supports UHS-II cards (on both slots), while the X-A7 can use UHS-I cards.

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-A7 and Panasonic Lumix DC-S1H and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1H has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-A7 lacks such a headphone port.

Studio photographers will appreciate that the Panasonic S1H (unlike the X-A7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1H is a recent model that features in the current product line-up of Panasonic. In contrast, the X-A7 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the X-A7 from Fujifilm. Further information on the features and operation of the X-A7 and S1H can be found, respectively, in the Fujifilm X-A7 Manual (free pdf) or the online Panasonic S1H Manual.

Review summary

So what conclusions can be drawn? Is the Fujifilm X-A7 better than the Panasonic S1H or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Fujifilm X-A7:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.5" vs 3.2") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2760k vs 2330k dots).
• More compact: Is smaller (119x68mm vs 151x114mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 732g or 70 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 3 months after the S1H).

Advantages of the Panasonic Lumix DC-S1H:

• High quality composites: Can combine several shots after pixel-shifting its sensor.
• 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.
• Better video: Provides higher definition movie capture (6K/30p vs 4K/30p).
• 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.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (9 vs 6 flaps/sec) to capture the decisive moment.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• 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 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the S1H is the clear winner of the contest (19 : 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 before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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-A7 and the Panasonic S1H 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 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-A7 or the S1H. 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.

Expert reviews

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], 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.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
