Canon 1Ds Mark III vs G1X Mark III
The Canon EOS-1Ds Mark III and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in August 2007 and October 2017. The 1Ds Mark III is a DSLR, while the G1X Mark III is a fixed lens compact. The cameras are based on a full frame (1Ds Mark III) and an APS-C (G1X Mark III) sensor. The 1Ds Mark III has a resolution of 21 megapixels, whereas the G1X Mark III 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 Canon EOS-1Ds Mark III and the Canon PowerShot G1 X Mark III? 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 1Ds Mark III and the Canon G1 X Mark III 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X Mark III is considerably smaller (63 percent) than the Canon 1Ds Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens built in, whereas the 1Ds Mark III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 1Ds Mark III and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G1X Mark III was launched at a lower price than the 1Ds Mark III, despite having a lens built in. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 1Ds Mark III features a full frame sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the G1X Mark III offers a higher resolution of 24 megapixels, compared with 21 MP of the 1Ds 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 3.72μm versus 6.41μm for the 1Ds Mark III). However, it should be noted that the G1X Mark III is much more recent (by 10 years and 1 month) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G1 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark III 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 Canon 1Ds Mark III are 28.1 x 18.7 inches or 71.3 x 47.5 cm for good quality, 22.5 x 15 inches or 57.1 x 38 cm for very good quality, and 18.7 x 12.5 inches or 47.5 x 31.7 cm for excellent quality prints.
The G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 Canon PowerShot G1 X Mark III are ISO 100 to ISO 25600 (no boost).
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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score.

Many modern cameras cannot only take still pictures, but also record videos. The G1X Mark III indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the G1X Mark III can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k 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.

One feature that is present on the 1Ds Mark III, but is missing on the G1X Mark III 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 G1X Mark III has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 1Ds Mark III does not have a selfie-screen.
The Canon G1 X Mark III 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 G1X Mark III 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 G1X Mark III only has one slot. The G1X Mark III 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.
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-1Ds Mark III and Canon PowerShot G1 X Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark III 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 G1X Mark III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G1X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the 1Ds Mark III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1Ds Mark III was succeeded by the Canon 1DX. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon 1Ds Mark III and the Canon G1 X Mark III? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the contest (21 : 9 points). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon G1 X Mark III place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 1Ds Mark III and the G1X 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.
This is where reviews by experts come in. 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
