Body comparison

The physical size and weight of the Sony HX99 and the Panasonic GH5 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Size Sony HX99 vs Panasonic GH5
Compare HX99 versus GH5 top
Comparison HX99 or GH5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH5 is considerably larger (130 percent) than the Sony HX99. It is noteworthy in this context that the GH5 is splash and dust-proof, while the HX99 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX99 has a lens built in, whereas the GH5 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 GH5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the HX99 gets 370 shots out of its Sony NP-BX1 battery, while the GH5 can take 410 images on a single charge of its Panasonic DMW-BLF19 power pack. The power pack in the HX99 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 HX99 was launched at a lower price than the GH5, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony HX99 features a 1/2.3-inch sensor and the Panasonic GH5 a Four Thirds sensor. The sensor area in the GH5 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Sony HX99 and Panasonic GH5 sensor measures

With 20.2MP, the GH5 offers a higher resolution than the HX99 (18MP), but the GH5 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.25μm for the HX99) due to its larger sensor. However, the HX99 is a somewhat more recent model (by 1 year and 7 months) than the GH5, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Panasonic GH5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH5 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Sony HX99 are 24.5 x 18.4 inches or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inches or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inches or 41.5 x 31.1 cm for excellent quality prints.

The Sony Cyber-shot DSC-HX99 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Panasonic Lumix DC-GH5 are ISO 200 to ISO 25600, 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.

HX99 versus GH5 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

One difference between the cameras concerns the presence of an on-board flash. The HX99 has one, while the GH5 does not. While the built-in flash of the HX99 is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 GH5 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 GH5 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 HX99 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GH5 uses SDXC cards. The GH5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the HX99 only has one slot. The GH5 supports UHS-II cards (on both slots), while the HX99 can use UHS-I cards.

It is notable that the GH5 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The HX99 does not feature such a mic input.

Studio photographers will appreciate that the Panasonic GH5 (unlike the HX99) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the HX99 and the GH5 have been discontinued, but can regularly be found used on ebay. The GH5 was replaced by the Panasonic GH5 II, while the HX99 does not have a direct successor. Further information on the features and operation of the HX99 and GH5 can be found, respectively, in the Sony HX99 Manual (free pdf) or the online Panasonic GH5 Manual.

  • 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 January 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the GH5 is the clear winner of the contest (26 : 8 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.

HX99 08:26 GH5

How about other alternatives? Do the specifications of the Sony HX99 and the Panasonic GH5 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the HX99 and the GH5 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 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
