Panasonic G9 vs Sony HX99

The Panasonic Lumix DC-G9 and the Sony Cyber-shot DSC-HX99 are two digital cameras that were revealed to the public, respectively, in November 2017 and August 2018. The G9 is a mirrorless interchangeable lens camera, while the HX99 is a fixed lens compact. The cameras are based on a Four Thirds (G9) and a 1/2.3-inch (HX99) sensor. The Panasonic has a resolution of 20.2 megapixels, whereas the Sony provides 18 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 Panasonic Lumix DC-G9 and the Sony Cyber-shot DSC-HX99? 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: Panasonic G9 vs Sony HX99

The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Sony HX99. 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 dimensions are rounded to the nearest millimeter.

Compare G9 versus HX99 top
Comparison G9 or HX99 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony HX99 is considerably smaller (55 percent) than the Panasonic G9. It is worth mentioning in this context that the G9 is splash and dust resistant, 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 G9 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 G9 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the HX99 can take 370 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 HX99 was launched at a lower price than the G9, 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: Panasonic G9 vs Sony HX99

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Sony HX99 a 1/2.3-inch sensor. The sensor area in the HX99 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Panasonic G9 and Sony HX99 sensor measures

With 20.2MP, the G9 offers a higher resolution than the HX99 (18MP), but the G9 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 9 months) than the G9, and its sensor might have benefitted from technological advances during this time that 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 resolution advantage of the Panasonic G9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Sony HX99 are 24.5 x 18.4 inch or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inch or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inch or 41.5 x 31.1 cm for excellent quality prints.

Unlike the HX99, the G9 has the capacity to capture high quality composite images (80.6MP) 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 Panasonic Lumix DC-G9 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-HX99 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

One feature that is present on the G9, but is missing on the HX99 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 G9 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 G9 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 G9 writes its imaging data to SDXC cards, while the HX99 uses SDXC or Memory Stick PRO Duo cards. The G9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the HX99 only has one slot. The G9 supports UHS-II cards (on both slots), while the HX99 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Panasonic G9 vs Sony HX99

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-G9 and Sony Cyber-shot DSC-HX99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9 has a hotshoe, while the HX99 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Panasonic G9 (unlike the HX99) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G9 and the HX99 are recent models that are part of the current product line-up. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Panasonic and Sony. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.

ilogo

Arguments in favor of the Sony Cyber-shot DSC-HX99:

  • Ready to shoot: Has an integrated lens, whereas the G9 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the G9).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Was introduced somewhat (9 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (26 : 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 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 Panasonic G9 and the Sony HX99 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 G9 or the HX99. 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: Panasonic G9 vs Sony HX99

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

Care should be taken when interpreting the review scores above, 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 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.
