Nikon D3000 vs Sony A99
The Nikon D3000 and the Sony Alpha SLT-A99 are two digital cameras that were announced, respectively, in July 2009 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D3000) and a full frame (A99) sensor. The Nikon has a resolution of 10 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 D3000 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.
Body comparison
The physical size and weight of the Nikon D3000 and the Sony A99 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 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 larger (34 percent) than the Nikon D3000. Moreover, the A99 is substantially heavier (51 percent) than the D3000. It is noteworthy in this context that the A99 is splash and dust-proof, while the D3000 does not feature any corresponding weather-sealing.
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.

Any camera decision will obviously take relative prices into account. 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 D3000 was launched at a markedly lower price (by 79 percent) than the A99, 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.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants 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.
Of the two cameras under consideration, the Nikon D3000 features an APS-C sensor and the Sony A99 a full frame sensor. The sensor area in the A99 is 128 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the A99 offers a higher resolution than the D3000 (10MP), but the A99 has smaller individual pixels (pixel pitch of 5.96μm versus 6.11μm for the D3000). Yet, the A99 is a much more recent model (by 3 years and 1 month) than the D3000, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
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 D3000 are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D3000 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. 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.
In terms of underlying technology, the D3000 is build around a CCD sensor, while the A99 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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. Of the two cameras under consideration, the A99 offers substantially better image quality than the D3000 (overall score 27 points higher). The advantage is based on 2.7 bits higher color depth, 2.9 EV in additional dynamic range, and 1.5 stops in additional 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 cannot only take still pictures, but also record videos. The A99 indeed provides for movie recording, while the D3000 does not. The highest resolution format that the A99 can use is 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A99 has an electronic viewfinder (2359k dots), while the D3000 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 D3000 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A99 has a higher magnification (0.71x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye.

One difference between the cameras concerns the presence of an on-board flash. The D3000 has one, while the A99 does not. While the built-in flash of the D3000 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 D3000 does not have a selfie-screen.The D3000 writes its imaging data to SDHC 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 D3000 only has one slot. The A99 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3000 cannot take advantage of Ultra High Speed SD cards.
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 Nikon D3000 and Sony Alpha SLT-A99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Sony A99 (unlike the D3000) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
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 D3000 and the A99 have been discontinued, but can regularly be found used on ebay. The D3000 was replaced by the Nikon D3100, while the A99 was followed by the Sony A99. Further information on the features and operation of the D3000 and A99 can be found, respectively, in the Nikon D3000 Manual (free pdf) or the online Sony A99 Manual.
Review summary
So what conclusions can be drawn? Is there a clear favorite between the Nikon D3000 and the Sony A99? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D3000:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.

If the number of relative strengths (bullet points above) is taken as a guide, the A99 is the clear winner of the contest (22 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 D3000 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D3000 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.
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 (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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
