Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds and the Leica M9? 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 and the Leica M9 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.

The M9 can be obtained in two different colors (black, silver), while the 1Ds 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 Leica M9 is considerably smaller (55 percent) than the Canon 1Ds. Moreover, the M9 is substantially lighter (54 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the M9 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (1Ds) and the Leica M Lens Catalog (M9).

Concerning battery life, the 1Ds gets 600 shots out of its Canon NP-E3 battery, while the M9 can take 550 images on a single charge of its Leica BLI-312 power pack. As can be seen in the images above, the 1Ds has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M9 was launched at a somewhat lower price (by 11 percent) than the 1Ds, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the M9 is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 18.1MP, the M9 offers a higher resolution than the 1Ds (11MP), but the M9 has smaller individual pixels (pixel pitch of 6.91μm versus 8.83μm for the 1Ds). Yet, the M9 is a much more recent model (by 6 years and 11 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inches or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inches or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.1 x 29.4 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inches or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inches or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inches or 34.4 x 22.9 cm for excellent quality prints.

The Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Leica M9 are ISO 80 to ISO 2500 (no boost).

In terms of underlying technology, the 1Ds is build around a CMOS sensor, while the M9 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.

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 consideration, the M9 has a markedly higher DXO score than the 1Ds (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 stops of reduced 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the M9 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 1Ds has a higher magnification than the one of the M9 (0.70x vs 0.68x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1Ds and Leica M9 along with similar information for a selection of comparators.

One feature that is present on the 1Ds, but is missing on the M9 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 writes its imaging data to Compact Flash cards, while the M9 uses SDXC 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. The table below provides an overview of the connectivity of the Canon EOS-1Ds and Leica M9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds (unlike the M9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds and the M9 have been discontinued, but can regularly be found used on ebay. The 1Ds was replaced by the Canon 1Ds Mark II, while the M9 was followed by the Leica M Typ 240. Further information on the features and operation of the 1Ds and M9 can be found, respectively, in the Canon 1Ds Manual (free pdf) or the online Leica M9 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1Ds or the Leica M9 – 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:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.68x).
• 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 (3 vs 2 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• 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 September 2002).

Advantages of the Leica M9:

• More detail: Has more megapixels (18.1 vs 11MP), which boosts linear resolution by 28%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
• Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
• More compact: Is smaller (139x80mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 680g or 54 percent) and is thus easier to take along.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
• More modern: Reflects 6 years and 11 months of technical progress since the 1Ds launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M9 emerges as the winner of the match-up (11 : 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.

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 and the M9 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.
