Panasonic GF1 vs Sony HX99
The Panasonic Lumix DMC-GF1 and the Sony Cyber-shot DSC-HX99 are two digital cameras that were revealed to the public, respectively, in September 2009 and August 2018. The GF1 is a mirrorless interchangeable lens camera, while the HX99 is a fixed lens compact. The cameras are based on a Four Thirds (GF1) and a 1/2.3-inch (HX99) sensor. The Panasonic has a resolution of 12 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 DMC-GF1 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.
The physical size and weight of the Panasonic GF1 and the Sony HX99 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 dimensions are rounded to the nearest millimeter.
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 (30 percent) than the Panasonic GF1. In this context, it is worth noting that neither the GF1 nor the HX99 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX99 has a lens built in, whereas the GF1 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 GF1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GF1 gets 380 shots out of its DMW-BLB13 battery, while the HX99 can take 370 images on a single charge of its NP-BX1 power pack. The power pack in the HX99 can be charged via the USB port, which can be very convenient when travelling.

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 HX99 was launched at a lower price than the GF1, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 GF1 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.
Despite having a smaller sensor, the HX99 offers a higher resolution of 18 megapixels, compared with 12 MP of the GF1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.25μm versus 4.33μm for the GF1). However, it should be noted that the HX99 is much more recent (by 9 years) than the GF1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony HX99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX99 for good quality output (200 dots per inch) amounts to 24.5 x 18.4 inches or 62.2 x 46.6 cm, for very good quality (250 dpi) 19.6 x 14.7 inches or 49.7 x 37.3 cm, and for excellent quality (300 dpi) 16.3 x 12.2 inches or 41.5 x 31.1 cm. The corresponding values for the Panasonic GF1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Panasonic Lumix DMC-GF1 has a native sensitivity range from ISO 100 to ISO 3200. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the HX99 provides a better video resolution than the GF1. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the HX99 has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The adjacent table lists some of the other core features of the Panasonic GF1 and Sony HX99 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The HX99 has a touchscreen, while the GF1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The HX99 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GF1 does not have a selfie-screen.
The GF1 writes its imaging data to SDHC cards, while the HX99 uses SDXC or Memory Stick PRO Duo cards. The HX99 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF1 cannot take advantage of Ultra High Speed SD cards.
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 DMC-GF1 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 GF1 has a hotshoe, while the HX99 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The HX99 is a recent model that features in the current product line-up of Sony. In contrast, the GF1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GF1 was succeeded by the Panasonic DMC-GF2. 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.
So how do things add up? Is there a clear favorite between the Panasonic GF1 and the Sony HX99? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the HX99 is the clear winner of the contest (20 : 9 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 GF1 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 incomplete and does no justice, for example, to the way the GF1 or the HX99 perform in practice. 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.
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], 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
