Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-3N and the Sony Alpha SLT-A58? 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 Sony NEX-3N and the Sony A58 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 width, height and depth dimensions are rounded to the nearest millimeter.

The NEX-3N can be obtained in two different colors (black, white), while the A58 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 A58 is considerably larger (80 percent) than the Sony NEX-3N. Moreover, the A58 is substantially heavier (83 percent) than the NEX-3N. In this context, it is worth noting that neither the NEX-3N nor the A58 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. 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.

Concerning battery life, the NEX-3N gets 480 shots out of its Sony NP-FW50 battery, while the A58 can take 690 images on a single charge of its Sony NP-FM500H power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The NEX-3N was launched at a somewhat lower price (by 17 percent) than the A58, which makes it more attractive for photographers on a tight budget. 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 size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A58 is 1 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.

With 19.8MP, the A58 offers a higher resolution than the NEX-3N (16MP), but the A58 has smaller individual pixels (pixel pitch of 4.31μm versus 4.78μm for the NEX-3N). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 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 NEX-3N has a native sensitivity range from ISO 200 to ISO 16000. The corresponding ISO settings for the Sony Alpha SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.

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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60i).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A58 has an electronic viewfinder (1440k 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 NEX-3N and Sony A58 along with similar information for a selection of comparators.

One feature that differentiates the A58 and the NEX-3N is in-body image stabilization (IBIS). The A58 reduces the risk of handshake-induced blur with all attached lenses, while the NEX-3N offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Concerning the storage of imaging data, both the NEX-3N and the A58 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-3N and Sony Alpha SLT-A58 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A58 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The NEX-3N does not feature such a mic input.

Both the NEX-3N and the A58 have been discontinued, but can regularly be found used on ebay. The NEX-3N was replaced by the Sony A5000, while the A58 was followed by the Sony A68. Further information on the features and operation of the NEX-3N and A58 can be found, respectively, in the Sony NEX-3N Manual (free pdf) or the online Sony A58 Manual.

Review summary

So what is the bottom line? Is the Sony NEX-3N better than the Sony A58 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Alpha NEX-3N:

• Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (110x62mm vs 129x95mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 223g or 45 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).

Arguments in favor of the Sony Alpha SLT-A58:

• More detail: Has more megapixels (19.8 vs 16MP), which boosts linear resolution by 11%.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (690 versus 480) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

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 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 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.

How about other alternatives? Do the specifications of the Sony NEX-3N and the Sony A58 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the NEX-3N and the A58 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
