Canon 5D Mark III vs Panasonic GX80
The Canon EOS 5D Mark III and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were announced, respectively, in March 2012 and April 2016. The 5D Mark III is a DSLR, while the GX80 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (5D Mark III) and a Four Thirds (GX80) sensor. The Canon has a resolution of 22.1 megapixels, whereas the Panasonic provides 15.8 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 Canon EOS 5D Mark III and the Panasonic Lumix DMC-GX80? 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 Canon 5D Mark III and the Panasonic GX80 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 size dimensions are rounded to the nearest millimeter.
The GX80 can be obtained in two different colors (black, silver), while the 5D Mark III 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 Panasonic GX80 is considerably smaller (51 percent) than the Canon 5D Mark III. Moreover, the GX80 is substantially lighter (55 percent) than the 5D Mark III. It is worth mentioning in this context that the 5D Mark III is splash and dust resistant, while the GX80 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 Canon EF Lens Catalog (5D Mark III) and the Micro Four Thirds Lens Catalog (GX80). Mirrorless cameras, such as the GX80, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the 5D Mark III gets 950 shots out of its LP-E6 battery, while the GX80 can take 290 images on a single charge of its DMW-BLG10 power pack. The power pack in the GX80 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 GX80 was launched at a markedly lower price (by 77 percent) than the 5D Mark 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.
The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Canon 5D Mark III features a full frame sensor and the Panasonic GX80 a Four Thirds sensor. The sensor area in the GX80 is 74 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 5D Mark III has a native 3:2 aspect ratio, while the one in the GX80 offers a 4:3 aspect.
With 22.1MP, the 5D Mark III offers a higher resolution than the GX80 (15.8MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 3.77μm for the GX80) due to its larger sensor. However, the GX80 is a much more recent model (by 4 years and 1 month) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inches or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inches or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm. The corresponding values for the Panasonic GX80 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Panasonic Lumix DMC-GX80 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 review, the 5D Mark III has a notably higher overall DXO score than the GX80 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.9 EV of lower dynamic range, and 1.8 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX80 provides a better video resolution than the 5D Mark III. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX80 has an electronic viewfinder (2765k dots), while the 5D Mark III has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 5D Mark III has a higher magnification than the one of the GX80 (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 5D Mark III and Panasonic GX80 in connection with corresponding information for a sample of similar cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the 5D Mark III, but is missing on the GX80 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.
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 GX80 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 Panasonic GX80 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 5D Mark III writes its imaging data to Compact Flash or SDXC cards, while the GX80 uses SDXC cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX80 only has one slot. The GX80 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 5D Mark III 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 Canon EOS 5D Mark III and Panasonic Lumix DMC-GX80 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark III has a microphone port, which is missing on the GX80. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Canon 5D Mark III (unlike the GX80) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GX80 is a recent model that features in the current product line-up of Panasonic. In contrast, the 5D Mark III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 5D Mark III was succeeded by the Canon 5D Mark IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what conclusions can be drawn? Which of the two cameras – the Canon 5D Mark III or the Panasonic GX80 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the GX80 emerges as the winner of the match-up (19 : 17 points). 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.
How about other alternatives? Do the specifications of the Canon 5D Mark III and the Panasonic GX80 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 says little about, for example, the shooting experience and imaging performance of the 5D Mark III and the GX80 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.
This is where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
