Panasonic FZ82 vs GX800

The Panasonic Lumix DC-FZ82 (called Panasonic FZ80 in some regions) and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were officially introduced in January 2017. The FZ82 is a fixed lens compact, while the GX800 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (FZ82) and a Four Thirds (GX800) sensor. The FZ82 has a resolution of 18 megapixels, whereas the GX800 provides 15.8 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-FZ82 and the Panasonic Lumix DMC-GX800? 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 physical size and weight of the Panasonic FZ82 and the Panasonic GX800 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.

The GX800 can be obtained in three different colors (black, silver, red), while the FZ82 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 GX800 is considerably smaller (43 percent) than the Panasonic FZ82. In this context, it is worth noting that neither the FZ82 nor the GX800 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ82 has a lens built in, whereas the GX800 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 GX800 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the FZ82 gets 330 shots out of its Panasonic DMW-BMB9 battery, while the GX800 can take 210 images on a single charge of its Panasonic DMW-BLH7 power pack. The power pack in the FZ82 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 FZ82 was launched at a lower price than the GX800, 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic FZ82 features a 1/2.3-inch sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 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.

Despite having a smaller sensor, the Panasonic FZ82 offers a higher resolution of 18 megapixels, compared with 15.8 MP of the Panasonic GX800. 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 3.77μm for the GX800). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 FZ82 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ82 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 GX800 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The Panasonic Lumix DC-FZ82 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 DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the FZ82 is build around a BSI-CMOS sensor, while the GX800 uses a CMOS 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). 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 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, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the FZ82 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic FZ82, the Panasonic GX800, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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 Panasonic GX800 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.

Concerning the storage of imaging data, both the FZ82 and the GX800 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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-FZ82 and Panasonic Lumix DMC-GX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the FZ82 has a hotshoe, while the GX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The FZ82 is a recent model that features in the current product line-up of Panasonic. In contrast, the GX800 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the GX800 from Panasonic. Further information on the features and operation of the FZ82 and GX800 can be found, respectively, in the Panasonic FZ82 Manual (free pdf) or the online Panasonic GX800 Manual.

Review summary

So what is the bottom line? Is the Panasonic FZ82 better than the Panasonic GX800 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Panasonic Lumix DC-FZ82:

• More detail: Offers more megapixels (18 vs 15.8MP) with a 7% higher linear resolution.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/500s) to freeze action.
• Ready to shoot: Has a lens built-in, whereas the GX800 requires a separate lens.
• Longer lasting: Can take more shots (330 versus 210) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.

Reasons to prefer the Panasonic Lumix DMC-GX800:

• 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.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (107x65mm vs 130x94mm) and will fit more readily into a bag.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (9 points each). 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 Panasonic FZ82 and the Panasonic GX800 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the FZ82 and the GX800 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.

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

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