Panasonic GM5 vs Sony A7R IV

The Panasonic Lumix DMC-GM5 and the Sony Alpha A7R IV are two digital cameras that were revealed to the public, respectively, in September 2014 and July 2019. Both the GM5 and the A7R IV are mirrorless interchangeable lens cameras that are based on a Four Thirds (GM5) and a full frame (A7R IV) sensor. The Panasonic has a resolution of 15.8 megapixels, whereas the Sony provides 60.2 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 DMC-GM5 and the Sony Alpha A7R IV? 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 GM5 and the Sony A7R IV. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The GM5 can be obtained in two different colors (black, silver), while the A7R IV is only available in black.

Size Panasonic GM5 vs Sony A7R IV
Compare GM5 versus A7R IV top
Comparison GM5 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 considerably larger (108 percent) than the Panasonic GM5. Moreover, the A7R IV is substantially heavier (215 percent) than the GM5. It is noteworthy in this context that the A7R IV is splash and dust-proof, while the GM5 does not feature any corresponding weather-sealing.

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 (GM5) 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 GM5 gets 220 shots out of its DMW-BLH7 battery, while the A7R IV can take 670 images on a single charge of its NP-FZ100 power pack. The power pack in the A7R IV can be charged via the USB port, 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, just use the right or left arrows in the table to switch to the respective camera.

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

The price is, of course, an important factor in any camera decision. 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. The GM5 was launched at a markedly lower price (by 79 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 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GM5 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 GM5 has a native 4:3 aspect ratio, while the one in the A7R IV offers a 3:2 aspect.

Panasonic GM5 and Sony A7R IV sensor measures

With 60.2MP, the A7R IV offers a higher resolution than the GM5 (15.8MP), but the A7R IV has marginally smaller individual pixels (pixel pitch of 3.76μm versus 3.77μm for the GM5). Yet, the A7R IV is a much more recent model (by 4 years and 10 months) than the GM5, 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 the A7R IV has no anti-alias filter installed, so that it can capture all the detail its 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 inch or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inch or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inch or 80.5 x 53.6 cm. The corresponding values for the Panasonic GM5 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 cm for excellent quality prints.

The A7R IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the GM5, the A7R IV has the capacity to capture high quality composite images (241MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Panasonic Lumix DMC-GM5 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 A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R IV provides a better video resolution than the GM5. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60p.

 

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 IV offers a substantially higher resolution than the one in the GM5 (5760k vs 1166k dots).

One feature that differentiates the A7R IV and the GM5 is in-body image stabilization (IBIS). The A7R IV reduces the risk of handshake-induced blur with all attached lenses, while the GM5 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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 GM5 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 GM5 and the A7R IV write their files to SDXC cards. The A7R IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the GM5 only has one slot. The A7R IV supports UHS-II cards (on both slots), while the GM5 can use UHS-I 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-GM5 and Sony Alpha A7R IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IV has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The GM5 lacks such a headphone port.

Studio photographers will appreciate that the Sony A7R IV (unlike the GM5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7R IV is a recent model that features in the current product line-up of Sony. In contrast, the GM5 has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the GM5 from Panasonic. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Panasonic GM5 or the Sony A7R IV – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • 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.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 4 years and 10 months of technical progress since the GM5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R IV is the clear winner of the contest (27 : 5 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.

GM5 05:27 A7R IV

How about other alternatives? Do the specifications of the Panasonic GM5 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the GM5 or the A7R IV perform in practice. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
