Sony A3000 vs NEX-3N
The Sony Alpha A3000 and the Sony Alpha NEX-3N are two digital cameras that were officially introduced, respectively, in August 2013 and February 2013. Both the A3000 and the NEX-3N are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The A3000 has a resolution of 19.8 megapixels, whereas the NEX-3N provides 16 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 Sony Alpha A3000 and the Sony Alpha NEX-3N? 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 side-by-side display below illustrates the physical size and weight of the Sony A3000 and the Sony NEX-3N. 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.
The NEX-3N can be obtained in two different colors (black, white), while the A3000 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-3N is considerably smaller (41 percent) than the Sony A3000. Moreover, the NEX-3N is substantially lighter (35 percent) than the A3000. In this context, it is worth noting that neither the A3000 nor the NEX-3N are weather-sealed.
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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Sony E-Mount Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The power pack in the A3000 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A3000 was launched at a markedly lower price (by 34 percent) than the NEX-3N, which puts it into a different market segment. 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.
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 an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-3N is 2 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the Sony A3000 offers a higher resolution of 19.8 megapixels, compared with 16 MP of the Sony NEX-3N. 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 4.25μm versus 4.78μm for the NEX-3N). However, it should be noted that the A3000 is a somewhat more recent model (by 6 months) than the NEX-3N, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The resolution advantage of the Sony A3000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A3000 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Sony NEX-3N are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.
The Sony Alpha A3000 has a native sensitivity range from ISO 100 to ISO 16000. The corresponding ISO settings for the Sony Alpha NEX-3N are ISO 200 to ISO 16000 (no boost).
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 A3000 has a notably higher overall DXO score than the NEX-3N (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.3 EV in additional dynamic range, and 0 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.
| DXO |
|8.||Sony RX1R||Full Frame||24.0||6000||4000||1080/60p||25.0||13.6||2537||91|
|11.||Sony RX1||Full Frame||24.0||6000||4000||1080/60p||25.1||14.3||2534||93|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60i).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A3000 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-3N relies on live view and the rear LCD for framing. That said, the NEX-3N can be equipped with an optional viewfinder – the FDA-SV1. The adjacent table lists some of the other core features of the Sony A3000 and Sony NEX-3N along with similar information for a selection of comparators.
Concerning the storage of imaging data, both the A3000 and the NEX-3N write their files to SDXC or Memory Stick PRO Duo cards.
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 Sony Alpha A3000 and Sony Alpha NEX-3N and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A3000 has a hotshoe, while the NEX-3N does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the A3000 and the NEX-3N have been discontinued, but can regularly be found used on eBay. The NEX-3N was replaced by the Sony A5000, while the A3000 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So how do things add up? Is there a clear favorite between the Sony A3000 and the Sony NEX-3N? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Sony Alpha A3000:
- More detail: Offers more megapixels (19.8 vs 16MP) with a 11% higher linear resolution.
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Easier framing: Has an electronic viewfinder for image composition and settings control.

- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (4 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x62mm vs 128x91mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 142g or 35 percent) and is thus easier to take along.
- More heavily discounted: Has been on the market for longer (launched in February 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (7 points each). 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A3000 or the NEX-3N perform in practice. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 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.
