Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D610 and the Sony Alpha A900? 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.
The physical size and weight of the Nikon D610 and the Sony A900 are illustrated 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 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 A900 is notably larger (15 percent) than the Nikon D610. Moreover, the A900 is markedly heavier (5 percent) than the D610. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D610 was launched at a markedly lower price (by 33 percent) than the A900, which puts it into a different 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
While the two cameras under review share the same sensor size, the A900 offers a slightly higher resolution of 24.4 megapixels, compared with 24.2 MP of the D610. This megapixels advantage translates into a 0.5 percent gain in linear resolution. On the other hand, these sensor specs imply that the A900 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.94μm versus 5.97μm for the D610). Moreover, it should be noted, that the D610 is much more recent (by 5 years) than the A900, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.
The Nikon D610 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Sony Alpha A900 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D610 provides substantially higher image quality than the A900, with an overall score that is 15 points higher. This advantage is based on 1.4 bits higher color depth, 2.1 EV in additional dynamic range, and 1 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D610 indeed provides movie recording capabilities, while the A900 does not. The highest resolution format that the D610 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The D610 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A900 has a higher magnification than the one of the D610 (0.74x vs 0.70x), 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 Nikon D610, the Sony A900, and comparable cameras.
|Canon 5D Mark II||optical||Y||3.0||920||fixed||n||1/8000s||3.9||n||n|
|Sony A99 II||2400||Y||3.0||1229||full-flex||n||1/8000s||12.0||n||Y|
One difference between the cameras concerns the presence of an on-board flash. The D610 has one, while the A900 does not. While the built-in flash of the D610 is not very powerful, it can at times be useful as a fill-in light.
The Nikon D610 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 D610 writes its imaging data to SDXC cards, while the A900 uses Compact Flash or Memory Stick PRO Duo cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 D610 and Sony Alpha A900 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.
The D610 is a recent model that features in the current product line-up of Nikon. In contrast, the A900 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the A900 was succeeded by the Sony A99. 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? Which of the two cameras – the Nikon D610 or the Sony A900 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon D610:
- Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.1 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (141x113mm vs 156x117mm) and thus needs less room in the bag.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More modern: Reflects 5 years of technical progress since the A900 launch.
Reasons to prefer the Sony Alpha A900:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.70x).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More heavily discounted: Has been around for much longer (launched in September 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the D610 is the clear winner of the match-up (12 : 4 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D610 or the A900. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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 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.
