Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-FZ100 and the Sony Alpha A7R? 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 side-by-side display below illustrates the physical size and weight of the Panasonic FZ100 and the Sony A7R. 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 A7R is notably larger (17 percent) than the Panasonic FZ100. It is noteworthy in this context that the A7R is splash and dust-proof, while the FZ100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ100 has a lens built in, whereas the A7R 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 A7R and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the FZ100 gets 410 shots out of its Panasonic DMW-BMB9 battery, while the A7R can take 340 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A7R can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The FZ100 was launched at a lower price than the A7R, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic FZ100 features a 1/2.3-inch sensor and the Sony A7R a full frame sensor. The sensor area in the A7R is 2979 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the FZ100 has a native 4:3 aspect ratio, while the one in the A7R offers a 3:2 aspect.

With 36.2MP, the A7R offers a higher resolution than the FZ100 (14MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 1.41μm for the FZ100) due to its larger sensor. Moreover, the A7R is a much more recent model (by 3 years and 2 months) than the FZ100, and its sensor will have benefitted from technological advances during this time that further 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 Sony A7R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Panasonic FZ100 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.

The Panasonic Lumix DMC-FZ100 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-6400. The corresponding ISO settings for the Sony Alpha A7R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

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.

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"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R provides a faster frame rate than the FZ100. It can shoot movie footage at 1080/60p, while the Panasonic is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R offers a substantially higher resolution than the one in the FZ100 (2400k vs 202k dots). The adjacent table lists some of the other core features of the Panasonic FZ100 and Sony A7R along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The FZ100 has one, while the A7R does not. While the built-in flash of the FZ100 is not very powerful, it can at times be useful as a fill-in light.

The FZ100 writes its imaging data to SDXC cards, while the A7R uses SDXC or Memory Stick PRO Duo cards. The A7R supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the FZ100 cannot take advantage of Ultra High Speed SD cards.

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 DMC-FZ100 and Sony Alpha A7R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the FZ100 does not provide wifi capability.

Both the FZ100 and the A7R have been discontinued, but can regularly be found used on ebay. The FZ100 was replaced by the Panasonic FZ150, while the A7R was followed by the Sony A7R II. Further information on the features and operation of the FZ100 and A7R can be found, respectively, in the Panasonic FZ100 Manual (free pdf) or the online Sony A7R Manual.

Review summary

So what conclusions can be drawn? Is the Panasonic FZ100 better than the Sony A7R or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Panasonic Lumix DMC-FZ100:

• 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 (11 vs 4 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the A7R requires a separate lens.
• More compact: Is smaller (124x82mm vs 127x94mm) and thus needs less room in the bag.
• Longer lasting: Can take more shots (410 versus 340) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been available for much longer (launched in July 2010).

Advantages of the Sony Alpha A7R:

• More detail: Has more megapixels (36.2 vs 14MP), which boosts linear resolution by 64%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2400k vs 202k dots).
• More detailed LCD: Has a higher resolution rear screen (1230k vs 460k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 2 months of technical progress since the FZ100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R is the clear winner of the contest (18 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

How about other alternatives? Do the specifications of the Panasonic FZ100 and the Sony A7R 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 FZ100 and the A7R 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 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.

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