Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III and the Sony Alpha A850? 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 Sony A850 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 width, height and depth measures are rounded to the nearest millimeter.

Size Canon 1Ds Mark III vs Sony A850
Compare 1Ds Mark III versus A850 top
Comparison 1Ds Mark III or A850 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A850 is notably smaller (24 percent) than the Canon 1Ds Mark III. Moreover, the A850 is substantially lighter (35 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the A850 can take 880 images on a single charge of its NP-FM500H 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. In order to provide similar functionality for the A850, Sony provides the VG-C90AM vertical grip as an optional accessory (see here on eBay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The A850 was launched at a markedly lower price (by 75 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

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. 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. 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.

Canon 1Ds Mark III and Sony A850 sensor measures

Despite having a slightly smaller sensor, the A850 offers a higher resolution of 24.4 megapixels, compared with 21 MP of the 1Ds Mark III. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.94μm versus 6.41μm for the 1Ds Mark III). However, it should be noted that the A850 is much more recent (by 2 years) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Sony A850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A850 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Canon 1Ds Mark III are 28.1 x 18.7 inch or 71.3 x 47.5 cm for good quality, 22.5 x 15 inch or 57.1 x 38 cm for very good quality, and 18.7 x 12.5 inch or 47.5 x 31.7 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 Sony Alpha A850 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

1Ds Mark III versus A850 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 A850 lacks this capability. 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 Mark III and the A850 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 viewfinder in the 1Ds Mark III offers a wider field of view (100%) than the one in the A850 (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds Mark III has a higher magnification (0.76x vs 0.74x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 1Ds Mark III, the Sony A850, and comparable cameras.

One feature that differentiates the A850 and the 1Ds Mark III is in-body image stabilization (IBIS). The A850 reduces the risk of handshake-induced blur with all attached lenses, while the 1Ds Mark III has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the A850 uses Compact Flash or Memory Stick PRO Duo cards. The A850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1Ds Mark III only has one slot.

 

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 Mark III and Sony Alpha A850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 1Ds Mark III and the A850 have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the A850 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.


Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1Ds Mark III and the Sony A850? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

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

  • More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.74x).
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (1800 versus 880) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

ilogo

Arguments in favor of the Sony Alpha A850:

  • More detail: Has more megapixels (24.4 vs 21MP), which boosts linear resolution by 8%.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • More compact: Is smaller (156x117mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 490g or 35 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the 1Ds Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A850 emerges as the winner of the match-up (8 : 6 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

1Ds Mark III 06:08 A850

How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Sony A850 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1Ds Mark III or the A850 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.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
