Canon 1Ds Mark III versus Canon 5D Mark III

The Canon EOS-1Ds Mark III and the Canon EOS 5D Mark III are two professional cameras that were revealed to the public, respectively, in August 2007 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 1Ds Mark III has a resolution of 21 megapixel, whereas the 5D Mark III provides 22.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1Ds Mark III vs Canon 5D Mark III

The physical size and weight of the Canon 1Ds Mark III and the Canon 5D Mark III are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 1Ds Mark III – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 5D Mark III is notably smaller (27 percent) than the Canon 1Ds Mark III. Moreover, the 5D Mark III is markedly lighter (31 percent) than the 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 since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the 5D Mark III can take 950 images on a single charge of its LP-E6 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 5D Mark III was launched at a markedly lower price (by 56 percent) than the 1Ds Mark III, which puts it into a different market segment. 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: Canon 1Ds Mark III vs Canon 5D Mark III

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

While the two cameras under review share the same sensor size, the 5D Mark III offers a slightly higher resolution of 22.1 megapixel, compared with 21 MP of the 1Ds Mark III. This megapixel advantage translates into a 3 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark III has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.25μm versus 6.41μm for the 1Ds Mark III). However, it should be noted that the 5D Mark III is much more recent (by 4 years and 6 months) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality.

Many modern cameras cannot only take still pictures, but also record videos. The 5D Mark III indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the 5D Mark III can use is 1080/30p.

Feature comparison: Canon 1Ds Mark III vs Canon 5D Mark III

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds Mark III and the 5D Mark III 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 adjacent table lists some of the other core features of the Canon 1Ds Mark III and Canon 5D Mark III along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the 1Ds Mark III and the 5D Mark III have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the 5D Mark III was followed by the Canon 5D Mark IV.

Review summary: Canon 1Ds Mark III vs Canon 5D Mark III

So how do things add up? Which of the two cameras – the Canon 1Ds Mark III or the Canon 5D Mark III – has the upper hand? The listing below highlights the relative strengths of the two models.


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

  • Longer lasting: Can take more shots (1800 versus 950) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

Arguments in favor of the Canon EOS 5D Mark III:

  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (152x116mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 435g or 31 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More modern: Reflects 4 years and 6 months of technical progress since the 1Ds Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark III is the clear winner of the contest (9 : 2 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1Ds Mark III and the 5D 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
