Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 1Ds Mark III and the Canon G12. 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.

Compare 1Ds Mark III versus G12 top
Comparison 1Ds Mark III or G12 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G12 is considerably smaller (65 percent) than the Canon 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the G12 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 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 Canon LP-E4 battery, while the G12 can take 370 images on a single charge of its Canon NB-7L 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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 G12 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.

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 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 G12 a 1/1.7-inch sensor. The sensor area in the G12 is 95 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 4.6. The sensor in the 1Ds Mark III has a native 3:2 aspect ratio, while the one in the G12 offers a 4:3 aspect.

Canon 1Ds Mark III and Canon G12 sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the G12 (10MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 2.07μm for the G12) due to its larger sensor. However, the G12 is a much more recent model (by 3 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 Canon G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 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 Canon PowerShot G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the 1Ds Mark III is build around a CMOS sensor, while the G12 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

1Ds Mark III versus G12 MP

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 G12, with an overall score that is 33 points higher. This advantage is based on 3.6 bits higher color depth, 0.8 EV in additional dynamic range, and 3.4 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.

One feature that is present on the 1Ds Mark III, but is missing on the G12 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the G12 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 G12 only has one slot.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1Ds Mark III or the Canon G12 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS-1Ds Mark III:

  • More detail: Offers more megapixels (21 vs 10MP) with a 48% higher linear resolution.
  • Better image quality: Scores substantially higher (33 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (3.6 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (3.4 stops ISO advantage).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 1.1 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (1800 versus 370) 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).


Advantages of the Canon PowerShot G12:

  • Broader imaging potential: Can capture not only stills but also 720/24p video.
  • More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Ready to shoot: Comes with an integrated lens, while the 1Ds Mark III requires a separate lens.
  • More compact: Is smaller (112x76mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 1Ds Mark III).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 3 years of technical progress since the 1Ds Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 1Ds Mark III is the clear winner of the match-up (16 : 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 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.

1Ds Mark III 16:10 G12

How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Canon G12 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 1Ds Mark III and the G12 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.

Expert reviews

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.

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

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
