Body comparison

An illustration of the physical size and weight of the Panasonic G9 II and the Sony A7R IV 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 dimensions are rounded to the nearest millimeter.

Size Panasonic G9 II vs Sony A7R IV
Compare G9 II versus A7R IV top
Comparison G9 II or A7R IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R IV is notably smaller (9 percent) than the Panasonic G9 II. However, the A7R IV is slightly heavier (1 percent) than the G9 II. 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 II) and the Sony FE Lens Catalog (A7R IV). 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 II gets 390 shots out of its Panasonic DMW-BLK22 battery, while the A7R IV can take 670 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 G9 II was launched at a markedly lower price (by 46 percent) than the A7R IV, which puts it into a different market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 G9 II features a Four Thirds sensor and the Sony A7R IV a full frame sensor. The sensor area in the A7R IV 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 II has a native 4:3 aspect ratio, while the one in the A7R IV offers a 3:2 aspect.

Panasonic G9 II and Sony A7R IV sensor measures

With 60.2MP, the A7R IV offers a higher resolution than the G9 II (25MP), but the A7R IV nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.00μm for the G9 II) due to its larger sensor. However, the G9 II is a much more recent model (by 4 years and 1 month) than the A7R IV, and its sensor will have benefitted from technological advances during this time that 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 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IV 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 II are 28.9 x 21.7 inches or 73.4 x 55.1 cm for good quality, 23.1 x 17.3 inches or 58.7 x 44.1 cm for very good quality, and 19.3 x 14.5 inches or 48.9 x 36.7 cm for excellent quality prints.

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 II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-25600. The corresponding ISO settings for the Sony Alpha A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the G9 II is build around a CMOS sensor, while the A7R IV 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 II versus A7R IV MP

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.
The G9 II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A7R IV does not have a selfie-screen.

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 II and the Sony A7R IV 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 G9 II and the A7R IV write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the G9 II and the A7R IV support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

Studio photographers will appreciate that the Sony A7R IV (unlike the G9 II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The G9 II is a recent model that features in the current product line-up of Panasonic. In contrast, the A7R IV has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7R IV was succeeded by the Sony A7R V. Further information on the features and operation of the G9 II and A7R IV can be found, respectively, in the Panasonic G9 II Manual (free pdf) or the online Sony A7R IV Manual.

Review summary

So what conclusions can be drawn? Is the Panasonic G9 II better than the Sony A7R IV or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Panasonic Lumix DC-G9 II:

  • Better video: Provides higher definition movie capture (5.7K/60p vs 4K/30p).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.8x vs 0.78x).
  • More detailed LCD: Has a higher resolution rear screen (1840k vs 1440k 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 data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
  • More modern: Reflects 4 years and 1 month of technical progress since the A7R IV launch.

ilogo

Advantages of the Sony Alpha A7R IV:

  • More detail: Has more megapixels (60.2 vs 25MP), which boosts linear resolution by 58%.
  • 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 (5760k vs 3680k dots).
  • Longer lasting: Gets more shots (670 versus 390) out of a single battery charge.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in July 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the A7R IV comes out slightly ahead of the G9 II (10 : 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 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 II 09:10 A7R IV

How about other alternatives? Do the specifications of the Panasonic G9 II and the Sony A7R IV 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G9 II or the A7R IV. 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 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
