Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-5N and the Sony Alpha A3000? 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

An illustration of the physical size and weight of the Sony NEX-5N and the Sony A3000 is provided 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.

The NEX-5N can be obtained in two different colors (black, silver), 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 A3000 is considerably larger (78 percent) than the Sony NEX-5N. Moreover, the A3000 is substantially heavier (53 percent) than the NEX-5N. In this context, it is worth noting that neither the NEX-5N nor the A3000 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, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Convert to Imperial

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 A3000 was launched at a markedly lower price (by 53 percent) than the NEX-5N, 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.

Sensor comparison

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A3000 is 2 percent smaller. 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 A3000 offers a higher resolution of 19.8 megapixels, compared with 16 MP of the NEX-5N. 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-5N). However, it should be noted that the A3000 is much more recent (by 2 years) than the NEX-5N, 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 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-5N 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 NEX-5N has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony Alpha A3000 are ISO 100 to ISO 16000 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 imaging performance. 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. 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).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range 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-5N relies on live view and the rear LCD for framing. That said, the NEX-5N can be equipped with an optional viewfinder – the FDA-EV1S. The following table reports on some other key feature differences and similarities of the Sony NEX-5N, the Sony A3000, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The NEX-5N has a touchscreen, while the A3000 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Concerning the storage of imaging data, both the NEX-5N and the A3000 write their files to SDXC or Memory Stick PRO Duo 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 Sony Alpha NEX-5N and Sony Alpha A3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the NEX-5N and the A3000 have been discontinued, but can regularly be found used on ebay. The NEX-5N was replaced by the Sony NEX-5R, while the A3000 does not have a direct successor. Further information on the features and operation of the NEX-5N and A3000 can be found, respectively, in the Sony NEX-5N Manual (free pdf) or the online Sony A3000 Manual.

Review summary

So how do things add up? Is the Sony NEX-5N better than the Sony A3000 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Sony Alpha NEX-5N:

• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 2.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (111x59mm vs 128x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 142g or 35 percent) and hence easier to carry around.
• More heavily discounted: Has been available for much longer (launched in August 2011).

Reasons to prefer the Sony Alpha A3000:

• More detail: Has more megapixels (19.8 vs 16MP), which boosts linear resolution by 11%.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
• More modern: Reflects 2 years of technical progress since the NEX-5N launch.

If the number of relative strengths (bullet points above) is taken as a guide, the NEX-5N emerges as the winner of the contest (8 : 6 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 Sony NEX-5N and the Sony A3000 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 NEX-5N and the A3000 in practical situations. 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.

Expert reviews

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], 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
