Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-FZ1000 II and the Panasonic Lumix DMC-GX85? 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

An illustration of the physical size and weight of the Panasonic FZ1000 II and the Panasonic GX85 is provided in the side-by-side display below. 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 GX85 can be obtained in two different colors (black, silver), while the FZ1000 II 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 GX85 is considerably smaller (34 percent) than the Panasonic FZ1000 II. In this context, it is worth noting that neither the FZ1000 II nor the GX85 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ1000 II has a lens built in, whereas the GX85 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 GX85 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the FZ1000 II gets 350 shots out of its Panasonic DMW-BLC12 battery, while the GX85 can take 290 images on a single charge of its Panasonic DMW-BLG10 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. 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. 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.

Sensor comparison

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

Of the two cameras under consideration, the Panasonic FZ1000 II features an one-inch sensor and the Panasonic GX85 a Four Thirds sensor. The sensor area in the GX85 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the FZ1000 II has a native 3:2 aspect ratio, while the one in the GX85 offers a 4:3 aspect.

Despite having a smaller sensor, the Panasonic FZ1000 II offers a higher resolution of 20 megapixels, compared with 15.8 MP of the Panasonic GX85. 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 2.41μm versus 3.77μm for the GX85). However, it should be noted that the FZ1000 II is much more recent (by 2 years and 10 months) than the GX85, 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 GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic FZ1000 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ1000 II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic GX85 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-FZ1000 II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX85 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the FZ1000 II is build around a BSI-CMOS sensor, while the GX85 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

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 FZ1000 II and the Panasonic GX85 both have 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 FZ1000 II and the GX85 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-FZ1000 II and Panasonic Lumix DMC-GX85 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the FZ1000 II has a microphone port, which is missing on the GX85. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the FZ1000 II and the GX85 are recent models that are part of the current product line-up. The GX85 replaced the earlier Panasonic GX7, while the FZ1000 II followed on from the Panasonic FZ1000. Further information on the features and operation of the FZ1000 II and GX85 can be found, respectively, in the Panasonic FZ1000 II Manual (free pdf) or the online Panasonic GX85 Manual.

Review summary

So what is the bottom line? Is the Panasonic FZ1000 II better than the Panasonic GX85 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Panasonic Lumix DC-FZ1000 II:

• More detail: Offers more megapixels (20 vs 15.8MP) with a 15% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (12 vs 8 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the GX85 requires a separate lens.
• Longer lasting: Can take more shots (350 versus 290) on a single battery charge.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 2 years and 10 months of technical progress since the GX85 launch.

Arguments in favor of the Panasonic Lumix DMC-GX85:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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 detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 2360k dots).
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (122x71mm vs 136x97mm) and will fit more readily into a bag.
• More heavily discounted: Has been around for much longer (launched in April 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the FZ1000 II emerges as the winner of the contest (11 : 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 FZ1000 II and the Panasonic GX85 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the FZ1000 II or the GX85. 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 expert reviews 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
