Body comparison

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

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

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D Mark III is considerably larger (174 percent) than the Panasonic GX9. Moreover, the 1D Mark III is substantially heavier (184 percent) than the GX9. It is noteworthy in this context that the 1D Mark III is splash and dust-proof, 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 Micro Four Thirds Lens Catalog (GX9) and the Canon EF Lens Catalog (1D Mark III). Mirrorless cameras, such as the Panasonic GX9, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the GX9 gets 260 shots out of its Panasonic DMW-BLG10 battery, while the 1D Mark III can take 2200 images on a single charge of its Canon LP-E4 power pack. As can be seen in the images above, the 1D 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, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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

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 GX9 was launched at a markedly lower price (by 81 percent) than the 1D Mark III, 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 size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 GX9 features a Four Thirds sensor and the Canon 1D Mark III an APS-H sensor. The sensor area in the 1D Mark III is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.3. The sensor in the GX9 has a native 4:3 aspect ratio, while the one in the 1D Mark III offers a 3:2 aspect.

Panasonic GX9 and Canon 1D Mark III sensor measures

Despite having a smaller sensor, the Panasonic GX9 offers a higher resolution of 20.2 megapixels, compared with 10.1 MP of the Canon 1D 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 7.21μm for the 1D Mark III). However, it should be noted that the GX9 is much more recent (by 10 years and 11 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 resolution advantage of the Panasonic GX9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX9 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Panasonic Lumix DC-GX9 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 Canon EOS-1D Mark III are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 50-6400.

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.

GX9 versus 1D Mark III MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 1D 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 GX9 has a higher magnification than the one of the 1D Mark III (0.70x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Panasonic GX9, the Canon 1D Mark III, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The GX9 has one, while the 1D Mark III does not. While the built-in flash of the GX9 is not very powerful, it can at times be useful as a fill-in light.

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 Panasonic GX9 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 GX9 writes its imaging data to SDXC cards, while the 1D Mark III uses Compact Flash or SDHC cards. The 1D 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. The GX9 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark III cannot take advantage of Ultra High Speed SD cards.

It is notable that the GX9 offers wifi support, while the 1D Mark III does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Canon 1D Mark III (unlike the GX9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GX9 and the 1D Mark III have been discontinued, but can regularly be found used on ebay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the GX9 does not have a direct successor. Further information on the features and operation of the GX9 and 1D Mark III can be found, respectively, in the Panasonic GX9 Manual (free pdf) or the online Canon 1D Mark III Manual.

ilogo

Reasons to prefer the Canon EOS-1D Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (2200 versus 260) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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.
  • More heavily discounted: Has been around for much longer (launched in February 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the GX9 is the clear winner of the match-up (21 : 10 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GX9 21:10 1D Mark III

How about other alternatives? Do the specifications of the Panasonic GX9 and the Canon 1D Mark III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the GX9 and the 1D Mark III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
