Body comparison

An illustration of the physical size and weight of the Panasonic G9 and the Sony A7C R is provided 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 A7C R can be obtained in two different colors (black, silver), while the G9 is only available in black.

Size Panasonic G9 vs Sony A7C R
Compare G9 versus A7C R top
Comparison G9 or A7C R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7C R is considerably smaller (34 percent) than the Panasonic G9. Moreover, the A7C R is markedly lighter (21 percent) than the G9. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (G9) and the Sony FE Lens Catalog (A7C R). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the G9 gets 400 shots out of its Panasonic DMW-BLF19 battery, while the A7C R can take 520 images on a single charge of its Sony NP-FZ100 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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

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 G9 was launched at a markedly lower price (by 43 percent) than the A7C R, which puts it into a different market segment. 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 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. 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 are more costly to manufacture and tend to 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 A7C R a full frame sensor. The sensor area in the A7C R is 278 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the G9 has a native 4:3 aspect ratio, while the one in the A7C R offers a 3:2 aspect.

Panasonic G9 and Sony A7C R sensor measures

With 60.2MP, the A7C R offers a higher resolution than the G9 (20.2MP), but the A7C R nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the G9) due to its larger sensor. Moreover, the A7C R is a much more recent model (by 5 years and 9 months) than the G9, 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 A7C R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7C R for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Panasonic G9 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The A7C R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the 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 Alpha A7C R are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the G9 is build around a CMOS sensor, while the A7C R uses a BSI-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.

G9 versus A7C R MP

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").

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

One feature that is present on the G9, but is missing on the A7C R 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, 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 G9 and the Sony A7C R 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.

The G9 writes its imaging data to SDXC cards, while the A7C R 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 A7C R only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

Studio photographers will appreciate that the Panasonic G9 (unlike the A7C R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7C R is a recent model that features in the current product line-up of Sony. In contrast, the G9 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G9 was succeeded by the Panasonic G9 II. Further information on the features and operation of the G9 and A7C R can be found, respectively, in the Panasonic G9 Manual (free pdf) or the online Sony A7C R Manual.

Review summary

So what conclusions can be drawn? Is the Panasonic G9 better than the Sony A7C R or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Panasonic Lumix DC-G9:

  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.83x vs 0.7x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in November 2017).

ilogo

Reasons to prefer the Sony Alpha A7C R:

  • More detail: Has more megapixels (60.2 vs 20.2MP), which boosts linear resolution by 76%.
  • 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 live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More compact: Is smaller (124x71mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 138g or 21 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (520 versus 400) out of a single battery charge.
  • More modern: Reflects 5 years and 9 months of technical progress since the G9 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (10 points each). 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.

G9 10:10 A7C R

How about other alternatives? Do the specifications of the Panasonic G9 and the Sony A7C R place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G9 or the A7C R. 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

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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