Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D X Mark III and the Panasonic Lumix DC-GX9? 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

An illustration of the physical size and weight of the Canon 1D X Mark III and the Panasonic GX9 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 GX9 can be obtained in two different colors (black, silver), while the 1DX Mark III is only available in black.

Size Canon 1D X Mark III vs Panasonic GX9
Compare 1DX Mark III versus GX9 top
Comparison 1DX Mark III or GX9 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX9 is considerably smaller (66 percent) than the Canon 1D X Mark III. Moreover, the GX9 is substantially lighter (72 percent) than the 1DX Mark III. It is worth mentioning in this context that the 1DX Mark III is splash and dust resistant, while the GX9 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 (1DX Mark III) and the Micro Four Thirds Lens Catalog (GX9). Mirrorless cameras, such as the GX9, 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 1DX Mark III gets 2850 shots out of its LP-E19 battery, while the GX9 can take 260 images on a single charge of its DMW-BLG10 power pack. As can be seen in the images above, the 1DX Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the GX9 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 GX9 was launched at a markedly lower price (by 87 percent) than the 1DX 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.

Sensor comparison

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 1D X Mark III features a full frame sensor and the Panasonic GX9 a Four Thirds sensor. The sensor area in the GX9 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 1DX Mark III has a native 3:2 aspect ratio, while the one in the GX9 offers a 4:3 aspect.

Canon 1D X Mark III and Panasonic GX9 sensor measures

Despite having a smaller sensor, the GX9 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the 1DX Mark III. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 6.57μm for the 1DX Mark III). Moreover, it should be noted that the 1DX Mark III is a somewhat more recent model (by 1 year and 10 months) than the GX9, and its sensor might 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 GX9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The 1DX Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D X Mark III has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-819200. The corresponding ISO settings for the Panasonic Lumix DC-GX9 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

1DX Mark III versus GX9 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait").

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX9 has an electronic viewfinder (2760k dots), while the 1DX 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 1DX Mark III has a higher magnification than the one of the GX9 (0.76x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D X Mark III and Panasonic GX9 along with similar information for a selection of comparators.

One feature that is present on the 1DX Mark III, but is missing on the GX9 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 GX9 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 Canon 1D X Mark III and the Panasonic GX9 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.

The 1DX Mark III writes its imaging data to CFexpress cards, while the GX9 uses SDXC cards. The 1DX Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX9 only has one slot.

It is notable that the 1DX Mark III has a microphone port, which is missing on the GX9. 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 1D X Mark III (unlike the GX9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the 1DX Mark III has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1DX Mark III and the GX9 are recent models that are part of the current product line-up. The GX9 replaced the earlier Panasonic GX8, while the 1DX Mark III followed on from the Canon 1DX Mark II. 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.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark III is the clear winner of the match-up (24 : 12 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.

1DX Mark III 24:12 GX9

How about other alternatives? Do the specifications of the Canon 1D X Mark III and the Panasonic GX9 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1DX Mark III or the GX9 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
