Panasonic GH1 vs Sony A6400
The Panasonic Lumix DMC-GH1 and the Sony Alpha A6400 are two enthusiast cameras that were officially introduced, respectively, in March 2009 and January 2019. Both the GH1 and the A6400 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GH1) and an APS-C (A6400) sensor. The Panasonic has a resolution of 12 megapixels, whereas the Sony provides 24 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-GH1 and the Sony Alpha A6400? 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.
An illustration of the physical size and weight of the Panasonic GH1 and the Sony A6400 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.
The GH1 can be obtained in two different colors (black, red), while the A6400 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6400 is notably smaller (28 percent) than the Panasonic GH1. However, the A6400 is markedly heavier (5 percent) than the GH1. It is noteworthy in this context that the A6400 is splash and dust-proof, 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 Micro Four Thirds Lens Catalog (GH1) and the Sony E-Mount Lens Catalog (A6400). 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 GH1 gets 300 shots out of its DMW-BLB13 battery, while the A6400 can take 410 images on a single charge of its NP-FW50 power pack. The power pack in the A6400 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.

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 two cameras under review were launched at the same price and fall into the same 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.
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 GH1 features a Four Thirds sensor and the Sony A6400 an APS-C sensor. The sensor area in the A6400 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GH1 has a native 4:3 aspect ratio, while the one in the A6400 offers a 3:2 aspect.
With 24MP, the A6400 offers a higher resolution than the GH1 (12MP), but the A6400 has smaller individual pixels (pixel pitch of 3.91μm versus 4.33μm for the GH1). Yet, the A6400 is a much more recent model (by 9 years and 10 months) than the GH1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A6400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6400 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 A6400 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Panasonic Lumix DMC-GH1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Sony Alpha A6400 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-102400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A6400 offers substantially better image quality than the GH1 (overall score 19 points higher). The advantage is based on 2.4 bits higher color depth, 2 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 A6400 provides a better video resolution than the GH1. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/24p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A6400 offers a substantially higher resolution than the one in the GH1 (2359k vs 1440k dots). The adjacent table lists some of the other core features of the Panasonic GH1 and Sony A6400 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A6400 has a touchscreen, while the GH1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.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, the A6400 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 GH1 writes its imaging data to SDHC cards, while the A6400 uses SDXC or Memory Stick PRO Duo cards. The A6400 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH1 cannot take advantage of Ultra High Speed SD cards.
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-GH1 and Sony Alpha A6400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
| NFC |
It is notable that the A6400 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the GH1 does not provide wifi capability.
The A6400 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.
So what conclusions can be drawn? Is the Panasonic GH1 better than the Sony A6400 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the count of relative strengths (bullet points above) is taken as a measure, the A6400 is the clear winner of the contest (21 : 2 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.
How about other alternatives? Do the specifications of the Panasonic GH1 and the Sony A6400 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 GH1 or the A6400. 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.
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], 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 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.
