Canon 1Ds Mark III versus Canon 350D

The Canon EOS-1Ds Mark III and the Canon EOS 350D (labelled XT in some countries) are two digital cameras that were announced, respectively, in August 2007 and February 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark III) and an APS-C (350D) sensor. The 1Ds Mark III has a resolution of 21 megapixel, whereas the 350D provides 8 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 350D

The physical size and weight of the Canon 1Ds Mark III and the Canon 350D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 – the 1Ds Mark III – represents the basis or 100 percent 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 350D is considerably smaller (50 percent) than the Canon 1Ds Mark III. Moreover, the 350D is substantially lighter (61 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the 350D 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 (as in the 1Ds Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (350D). You can find a comprehensive 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 350D can take 400 images on a single charge of its NB-2LH power pack.

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

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 350D was launched at a markedly lower price (by 89 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 350D

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Canon 350D an APS-C sensor. The sensor area in the 350D is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1Ds Mark III and Canon 350D sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the 350D (8MP), but the 1Ds Mark III nevertheless has the same individual pixel size (pixel pitch of 6.41μm) as the 350D due to its larger sensor. It is noteworthy in this context that the 1Ds Mark III is a somewhat more recent model (by 2 years and 6 months) than the 350D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

1Ds Mark III versus 350D MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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 350D, with an overall score that is 20 points higher. This advantage is based on 2.2 bits higher color depth, 1.2 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

The 1Ds Mark III offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 350D lacks this capability. Both cameras are still-image focused and cannot record videos.

Feature comparison: Canon 1Ds Mark III vs Canon 350D

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds Mark III and the 350D 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 table below summarizes some of the other core capabilities of the Canon 1Ds Mark III and Canon 350D in connection with corresponding information for a sample of similar cameras.

Both the 1Ds Mark III and the 350D have been discontinued, but can regularly be found used on eBay. The 350D was replaced by the Canon 400D, while the 1Ds Mark III was followed by the Canon 1DX.

Review summary: Canon 1Ds Mark III vs Canon 350D

So what is the bottom line? Which of the two cameras – the Canon 1Ds Mark III or the Canon 350D – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


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

  • More detail: Offers more megapixels (21 vs 8MP) with a 62% higher linear resolution.
  • Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.2 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 115k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (1800 versus 400) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Reflects 2 years and 6 months of technical progress since the 350D launch.

Advantages of the Canon EOS 350D:

  • More compact: Is smaller (127x94mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 845g or 61 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2005).

If the count of relative strengths (bullet points above) is taken as a measure, the 1Ds Mark III is the clear winner of the match-up (13 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

1Ds Mark III 13:05 350D

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 350D handle or perform in practice. 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. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 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.
