Nikon D700 vs Sony A99
The Nikon D700 and the Sony Alpha SLT-A99 are two digital cameras that were revealed to the public, respectively, in July 2008 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Nikon has a resolution of 12.1 megapixels, whereas the Sony provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D700 and the Sony Alpha SLT-A99? 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.
An illustration of the physical size and weight of the Nikon D700 and the Sony A99 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 size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A99 is notably smaller (10 percent) than the Nikon D700. Moreover, the A99 is markedly lighter (24 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A99 was somewhat cheaper (by 7 percent) than the D700 at launch, but both cameras fall into the same price category. 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.
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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A99 is 1 percent smaller. 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a slightly smaller sensor, the A99 offers a higher resolution of 24 megapixels, compared with 12.1 MP of the D700. 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 5.96μm versus 8.43μm for the D700). However, it should be noted that the A99 is much more recent (by 4 years and 2 months) than the D700, 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 A99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon D700 are 21.3 x 14.2 inches or 54.1 x 36 cm for good quality, 17 x 11.3 inches or 43.2 x 28.8 cm for very good quality, and 14.2 x 9.4 inches or 36 x 24 cm for excellent quality prints.
The Nikon D700 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha SLT-A99 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.
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. Of the two cameras under consideration, the A99 has a markedly higher DXO score than the D700 (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1.5 bits higher color depth, 1.8 EV in additional dynamic range, and 0.6 stops of reduced low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The A99 indeed provides for movie recording, while the D700 does not. The highest resolution format that the A99 can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A99 has an electronic viewfinder (2359k dots), while the D700 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the A99 offers a wider field of view (100%) than the one in the D700 (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the D700 has a higher magnification (0.72x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D700 and Sony A99 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D700 has one, while the A99 does not. While the built-in flash of the D700 is not very powerful, it can at times be useful as a fill-in light.The A99 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D700 does not have a selfie-screen.
The Nikon D700 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The D700 writes its imaging data to Compact Flash cards, while the A99 uses SDXC or Memory Stick PRO Duo cards. The A99 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D700 only has one slot.
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 Nikon D700 and Sony Alpha SLT-A99 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.
Travel and landscape photographers will find it useful that the A99 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the D700 and the A99 have been discontinued, but can regularly be found used on eBay. The D700 was replaced by the Nikon D800, while the A99 was followed by the Sony A99 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.
So how do things add up? Is there a clear favorite between the Nikon D700 and the Sony A99? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Nikon D700:
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.72x vs 0.71x).
- Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (1000 versus 500) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in July 2008).
Reasons to prefer the Sony Alpha SLT-A99:
- More detail: Has more megapixels (24 vs 12.1MP), which boosts linear resolution by 41%.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- More framing info: Has an electronic viewfinder that displays shooting data.

- More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
- More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Less heavy: Has a lower weight (by 262g or 24 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 4 years and 2 months of technical progress since the D700 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the A99 is the clear winner of the contest (15 : 8 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Nikon D700 and the Sony A99 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D700 and the A99 in practical situations. 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 ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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 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.
