Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III and the Canon PowerShot G15? 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 1Ds Mark III and the Canon G15 is provided 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 measures are rounded to the nearest millimeter.

Compare 1Ds Mark III versus G15 top
Comparison 1Ds Mark III or G15 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G15 is considerably smaller (66 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 G15 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 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 G15 can take 350 images on a single charge of its NB-10L 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.

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

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G15 was launched at a lower price than the 1Ds Mark III, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 G15 a 1/1.7-inch sensor. The sensor area in the G15 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 G15 offers a 4:3 aspect.

Canon 1Ds Mark III and Canon G15 sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the G15 (12MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 1.89μm for the G15) due to its larger sensor. However, the G15 is a much more recent model (by 5 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 inch or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inch or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inch or 47.5 x 31.7 cm. The corresponding values for the Canon G15 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 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 G15 are ISO 80 to ISO 12800 (no boost).

1Ds Mark III versus G15 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the 1Ds Mark III provides substantially higher image quality than the G15, with an overall score that is 34 points higher. This advantage is based on 4.1 bits higher color depth, 0.5 EV in additional dynamic range, and 3.3 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Studio photographers will appreciate that the Canon 1Ds Mark III (unlike the G15) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds Mark III and the G15 have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the G15 was followed by the Canon G16. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1Ds Mark III and the Canon G15? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


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

  • More detail: Offers more megapixels (21 vs 12MP) with a 35% higher linear resolution.
  • Better image quality: Scores substantially higher (34 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (4.1 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (3.3 stops ISO advantage).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 2.1 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 350) 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.
  • More heavily discounted: Has been available for much longer (launched in August 2007).


Arguments in favor of the Canon PowerShot G15:

  • Broader imaging potential: Can capture not only stills but also 1080/24p video.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • Ready to shoot: Comes with an integrated lens, while the 1Ds Mark III requires a separate lens.
  • More compact: Is smaller (107x76mm 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 5 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 (13 : 9 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 13:09 G15

How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Canon G15 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 remains incomplete and does no justice, for example, to the way the 1Ds Mark III or the G15 perform in practice. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
