Canon 1Ds vs Leica M8

The Canon EOS-1Ds and the Leica M8 are two digital cameras that were revealed to the public, respectively, in September 2002 and September 2006. The 1Ds is a DSLR, while the M8 is a rangefinder-style mirrorless camera. The cameras are based on a full frame (1Ds) and an APS-H (M8) sensor. The Canon has a resolution of 11 megapixels, whereas the Leica provides 10.4 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 and the Leica M8? 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 M8 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The M8 can be obtained in two different colors (black, silver), while the 1Ds is only available in black.

Size Canon 1Ds vs Leica M8
Compare 1Ds versus M8 top
Comparison 1Ds or M8 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M8 is considerably smaller (55 percent) than the Canon 1Ds. Moreover, the M8 is substantially lighter (53 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the M8 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) and the Leica M Lens Catalog (M8).

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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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

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 M8 was launched at a markedly lower price (by 39 percent) than the 1Ds, which puts it into a different market segment. 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.

 

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 features a full frame sensor and the Leica M8 an APS-H sensor. The sensor area in the M8 is 43 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1Ds and Leica M8 sensor measures

With 11MP, the 1Ds offers a slightly higher resolution than the M8 (10.4MP), but the 1Ds nevertheless has larger individual pixels (pixel pitch of 8.83μm versus 6.84μm for the M8) due to its larger sensor. However, the M8 is a much more recent model (by 3 years and 11 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the M8 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 M8 are ISO 160 to ISO 2500 (no boost).

1Ds versus M8 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under review, the 1Ds has a notably higher overall DXO score than the M8 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.3 EV of lower dynamic range, and 0.5 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.

Neither the 1Ds nor the M8 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.
 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the M8 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.

One feature that is present on the 1Ds, but is missing on the M8 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 M8 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.

Studio photographers will appreciate that the Canon 1Ds (unlike the M8) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds and the M8 have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, while the M8 was followed by the Leica M9. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.


Review summary

So what is the bottom line? Is there a clear favorite between the Canon 1Ds and the Leica M8? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS-1Ds:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • 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).

ilogo

Reasons to prefer the Leica M8:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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 674g or 53 percent) and is thus easier to take along.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
  • More modern: Reflects 3 years and 11 months of technical progress since the 1Ds launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 1Ds comes out slightly ahead of the M8 (9 : 8 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 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 09:08 M8

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 or the M8 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 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 (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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
