Sony A900 versus Canon 5D Mark II

The Sony Alpha A900 and the Canon EOS 5D Mark II are two professional cameras that were revealed to the public in September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Sony has a resolution of 24.4 megapixel, whereas the Canon provides 21 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: Sony A900 vs Canon 5D Mark II

The physical size and weight of the Sony A900 and the Canon 5D Mark II 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 dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the A900 – represents 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 5D Mark II is notably smaller (5 percent) than the Sony A900. Moreover, the 5D Mark II is markedly lighter (5 percent) than the A900. 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 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 A900 gets 880 shots out of its NP-FM500H battery, while the 5D Mark II can take 850 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 A900 was launched at a somewhat lower price (by 14 percent) than the 5D Mark II, 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: Sony A900 vs Canon 5D Mark II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Sony A900 and Canon 5D Mark II sensor measures

Despite having a slightly smaller sensor, the Sony A900 offers a higher resolution of 24.4 megapixel, compared with 21 MP of the Canon 5D Mark II. This megapixel 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 5D Mark II). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

For most cameras, data on sensor performance has been reported by DXO Mark. 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 image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The 5D Mark II indeed provides for movie recording, while the A900 does not. The highest resolution format that the 5D Mark II can use is 1080/30p.

 

Feature comparison: Sony A900 vs Canon 5D Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. The A900 and the 5D Mark II 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 Sony A900 and Canon 5D Mark II along with similar information for a selection of comparators.

Review summary: Sony A900 vs Canon 5D Mark II

So what conclusions can be drawn? Is there a clear favorite between the Sony A900 and the Canon 5D Mark II? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Sony Alpha A900:

  • More detail: Offers more megapixels (24.4 vs 21MP) with a 8% higher linear resolution.
  • Faster burst: Shoots at higher frequency (5 vs 3.9 flaps/sec) to capture the decisive moment.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).

ilogo

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

  • Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.

If the number of relative strengths (bullet points above) is taken as a guide, the A900 emerges as the winner of the contest (4 : 2 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A900 or the 5D Mark II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
