Nikon D700 versus Sony A900

The Nikon D700 and the Sony Alpha A900 are two digital cameras that were revealed to the public, respectively, in July 2008 and September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Nikon has a resolution of 12.1 megapixel, whereas the Sony provides 24.4 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: Nikon D700 vs Sony A900

The physical size and weight of the Nikon D700 and the Sony A900 are illustrated 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 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 side – the D700 – 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 Nikon D700 and the Sony A900are of equal size. However, the A900 is markedly lighter (17 percent) than the D700. 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 D700 gets 1000 shots out of its EN-EL3e battery, while the A900 can take 880 images on a single charge of its NP-FM500H power pack.

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

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same 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: Nikon D700 vs Sony A900

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (D700) and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Nikon D700 and Sony A900 sensor measures

With 24.4MP, the A900 offers a higher resolution than the D700 (12.1MP), but the A900 has smaller individual pixels (pixel pitch of 5.94μm versus 8.43μm for the D700). 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.

D700 versus A900 MP

For many 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The D700 offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The A900 lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Nikon D700 vs Sony A900

Apart from body and sensor, cameras can and do differ across a variety of features. The D700 and the A900 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 following table reports on some other key feature differences and similarities of the Nikon D700, the Sony A900, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Nikon D700 vs Sony A900

So what conclusions can be drawn? Is there a clear favorite between the Nikon D700 and the Sony A900? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Nikon D700:

  • Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (1000 versus 880) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.

ilogo

Reasons to prefer the Sony Alpha A900:

  • More detail: Has more megapixels (24.4 vs 12.1MP), which boosts linear resolution by 42%.
  • Less heavy: Has a lower weight (by 179g or 17 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.

If the number of relative strengths (bullet points above) is taken as a guide, the D700 comes out slightly ahead of the A900 (4 : 3 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.

D700 04:03 A900

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the D700 or the A900. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
