Canon 1Ds Mark III vs Panasonic GM5
The Canon EOS-1Ds Mark III and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in August 2007 and September 2014. The 1Ds Mark III is a DSLR, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds Mark III) and a Four Thirds (GM5) sensor. The Canon has a resolution of 21 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-1Ds Mark III and the Panasonic Lumix DMC-GM5? 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
The physical size and weight of the Canon 1Ds Mark III and the Panasonic GM5 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 dimensions are rounded to the nearest millimeter.
The GM5 can be obtained in two different colors (black, silver), while the 1Ds 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 GM5 is considerably smaller (75 percent) than the Canon 1Ds Mark III. Moreover, the GM5 is substantially lighter (85 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the GM5 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 (1Ds Mark III) and the Micro Four Thirds Lens Catalog (GM5). Mirrorless cameras, such as the GM5, 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 1Ds Mark III gets 1800 shots out of its Canon LP-E4 battery, while the GM5 can take 220 images on a single charge of its Panasonic DMW-BLH7 power pack. As can be seen in the images above, the 1Ds Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 GM5 was launched at a markedly lower price (by 91 percent) than the 1Ds 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.
Sensor comparison
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 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 1Ds Mark III has a native 3:2 aspect ratio, while the one in the GM5 offers a 4:3 aspect.
With 21MP, the 1Ds Mark III offers a higher resolution than the GM5 (15.8MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 3.77μm for the GM5) due to its larger sensor. However, the GM5 is a much more recent model (by 7 years) than the 1Ds Mark III, 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 Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Panasonic GM5 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-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GM5 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 1Ds Mark III provides substantially higher image quality than the GM5, with an overall score that is 14 points higher. This advantage is based on 1.9 bits higher color depth, 0.3 EV in additional dynamic range, and 1.2 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 can also record movies. The GM5 indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the GM5 can use is 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GM5 has an electronic viewfinder (1166k dots), while the 1Ds 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 1Ds Mark III has a higher magnification than the one of the GM5 (0.76x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One feature that is present on the 1Ds Mark III, but is missing on the GM5 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 GM5 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 GM5 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the GM5 uses SDXC cards. The 1Ds Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the GM5 only has one slot. The GM5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1Ds Mark III cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
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.

It is notable that the GM5 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1Ds Mark III does not provide wifi capability.
Studio photographers will appreciate that the Canon 1Ds Mark III (unlike the GM5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1Ds Mark III and the GM5 have been discontinued, but can regularly be found used on ebay. The 1Ds Mark III was replaced by the Canon 1DX, while the GM5 does not have a direct successor. Further information on the features and operation of the 1Ds Mark III and GM5 can be found, respectively, in the Canon 1Ds Mark III Manual (free pdf) or the online Panasonic GM5 Manual.
Review summary
So what conclusions can be drawn? Is the Canon 1Ds Mark III better than the Panasonic GM5 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS-1Ds Mark III:
- More detail: Offers more megapixels (21 vs 15.8MP) with a 18% higher linear resolution.
- Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.46x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/500s) to freeze action.

- Longer lasting: Can take more shots (1800 versus 220) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- 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 available for much longer (launched in August 2007).
Arguments in favor of the Panasonic Lumix DMC-GM5:
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (5.8 vs 5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (99x60mm vs 150x160mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 1174g or 85 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
- More modern: Reflects 7 years of technical progress since the 1Ds Mark III launch.
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (14 points each). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Panasonic GM5 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 remains incomplete and does no justice, for example, to the way the 1Ds Mark III or the GM5 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 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available. |
The above review scores should be interpreted 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
