Body comparison

The physical size and weight of the Sony A7 III and the Panasonic GH1 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

The GH1 can be obtained in two different colors (black, red), while the A7 III is only available in black.

Size Sony A7 III vs Panasonic GH1
Compare A7 III versus GH1 top
Comparison A7 III or GH1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH1 is notably smaller (8 percent) than the Sony A7 III. Moreover, the GH1 is substantially lighter (41 percent) than the A7 III. It is worth mentioning in this context that the A7 III is splash and dust resistant, while the GH1 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 Sony FE Lens Catalog (A7 III) and the Micro Four Thirds Lens Catalog (GH1). 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 A7 III gets 610 shots out of its Sony NP-FZ100 battery, while the GH1 can take 300 images on a single charge of its Panasonic DMW-BLB13 power pack. The power pack in the A7 III can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 GH1 was launched at a markedly lower price (by 55 percent) than the A7 III, 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. 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 Sony A7 III features a full frame sensor and the Panasonic GH1 a Four Thirds sensor. The sensor area in the GH1 is 73 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the A7 III has a native 3:2 aspect ratio, while the one in the GH1 offers a 4:3 aspect.

Sony A7 III and Panasonic GH1 sensor measures

With 24MP, the A7 III offers a higher resolution than the GH1 (12MP), but the A7 III nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.33μm for the GH1) due to its larger sensor. Moreover, the A7 III is a much more recent model (by 8 years and 11 months) than the GH1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony A7 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic GH1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The A7 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A7 III has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Panasonic Lumix DMC-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the A7 III is build around a BSI-CMOS sensor, while the GH1 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.

A7 III versus GH1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the A7 III provides substantially higher image quality than the GH1, with an overall score that is 32 points higher. This advantage is based on 3.4 bits higher color depth, 3.1 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One feature that differentiates the A7 III and the GH1 is in-body image stabilization (IBIS). The A7 III reduces the risk of handshake-induced blur with all attached lenses, while the GH1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The GH1 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the A7 III 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, the A7 III is one of those camera that have an additional 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 Sony A7 III has 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 A7 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GH1 uses SDHC cards. The A7 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH1 only has one slot. The A7 III supports UHS-II cards on its first slot and UHS-I on its second one, while the GH1 cannot take advantage of Ultra High Speed SD cards.

It is notable that the A7 III has a headphone jack, which is not present on the GH1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

The A7 III is a recent model that features in the current product line-up of Sony. In contrast, the GH1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the GH1 was succeeded by the Panasonic GH2. Further information on the features and operation of the A7 III and GH1 can be found, respectively, in the Sony A7 III Manual (free pdf) or the online Panasonic GH1 Manual.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GH1:

  • 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.
  • Less heavy: Has a lower weight (by 265g or 41 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in March 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the A7 III is the clear winner of the match-up (27 : 6 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.

A7 III 27:06 GH1

How about other alternatives? Do the specifications of the Sony A7 III and the Panasonic GH1 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 says little about, for example, the shooting experience and imaging performance of the A7 III and the GH1 in practical situations. 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.

The review scores listed above should be treated 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 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.
