Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-GX9 and the Sony Cyber-shot DSC-H400? 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 side-by-side display below illustrates the physical size and weight of the Panasonic GX9 and the Sony H400. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The GX9 can be obtained in two different colors (black, silver), while the H400 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 Sony H400 is notably larger (38 percent) than the Panasonic GX9. In this context, it is worth noting that neither the GX9 nor the H400 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the H400 has a lens built in, whereas the GX9 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GX9 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GX9 gets 260 shots out of its Panasonic DMW-BLG10 battery, while the H400 can take 300 images on a single charge of its Sony NP-BX1 power pack. The power pack in the GX9 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 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 H400 was launched at a lower price than the GX9, despite having a lens built in. 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.

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GX9 features a Four Thirds sensor and the Sony H400 a 1/2.3-inch sensor. The sensor area in the H400 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 20.2MP, the GX9 offers a slightly higher resolution than the H400 (19.9MP), but the GX9 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.19μm for the H400) due to its larger sensor. Moreover, the GX9 is a much more recent model (by 4 years) than the H400, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The Panasonic Lumix DC-GX9 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 Sony Cyber-shot DSC-H400 are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the GX9 is build around a CMOS sensor, while the H400 uses a CCD 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.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 GX9 provides a higher video resolution than the H400. It can shoot video footage at 4K/30p, while the Sony is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GX9 offers a substantially higher resolution than the one in the H400 (2760k vs 210k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX9, the Sony H400, and comparable cameras.

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 GX9 has a touchscreen, while the H400 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, the GX9 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 GX9 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 GX9 writes its imaging data to SDXC cards, while the H400 uses SDXC or Memory Stick PRO Duo cards. The GX9 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the H400 cannot take advantage of Ultra High Speed SD 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 Panasonic Lumix DC-GX9 and Sony Cyber-shot DSC-H400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX9 has a hotshoe, while the H400 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the GX9 and the H400 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Panasonic and Sony. Further information on the features and operation of the GX9 and H400 can be found, respectively, in the Panasonic GX9 Manual (free pdf) or the online Sony H400 Manual.

Review summary

So how do things add up? Is the Panasonic GX9 better than the Sony H400 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Panasonic Lumix DC-GX9:

• 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.
• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 210k dots).
• More detailed LCD: Has a higher resolution rear screen (1240k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (9 vs 0.7 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.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More compact: Is smaller (124x72mm vs 130x95mm) and thus needs less room in the bag.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years of technical progress since the H400 launch.

Arguments in favor of the Sony Cyber-shot DSC-H400:

• Ready to shoot: Has an integrated lens, whereas the GX9 necessitates an extra lens.
• Longer lasting: Gets more shots (300 versus 260) out of a single battery charge.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been around for much longer (launched in February 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the GX9 is the clear winner of the match-up (20 : 4 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 Panasonic GX9 and the Sony H400 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 GX9 or the H400. 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 hands-on reviews by experts 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
