Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha 7S II 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7S II 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 width, height and depth measures are rounded to the nearest millimeter.

The NEX-3N can be obtained in two different colors (black, white), while the A7S II is only available in black.

Compare A7S II versus NEX-3N top
Comparison A7S II or NEX-3N rear

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 (44 percent) than the Sony A7S II. Moreover, the NEX-3N is substantially lighter (57 percent) than the A7S II. It is worth mentioning in this context that the A7S II is splash and dust resistant, while the NEX-3N 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Sony FE Lens Catalog (A7S II) and the Sony E-Mount Lens Catalog (NEX-3N). 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 A7S II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 NEX-3N was launched at a markedly lower price (by 83 percent) than the A7S II, 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 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.

Of the two cameras under consideration, the Sony A7S II features a full frame sensor and the Sony NEX-3N an APS-C sensor. The sensor area in the NEX-3N is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the A7S II uses a more advanced image processing engine (BIONZ X) than the NEX-3N (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

Sony A7S II and Sony NEX-3N sensor measures

Despite having a smaller sensor, the NEX-3N offers a higher resolution of 16 megapixels, compared with 12 MP of the A7S II. 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 4.78μm versus 8.40μm for the A7S II). Moreover, it should be noted that the A7S II is much more recent (by 2 years and 6 months) than the NEX-3N, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony NEX-3N implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3N for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.

The Sony Alpha 7S II has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Sony Alpha NEX-3N are ISO 200 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.

A7S II versus NEX-3N MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the A7S II provides substantially higher image quality than the NEX-3N, with an overall score that is 11 points higher. This advantage is based on 0.8 bits higher color depth, 0.8 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A7S II provides a higher video resolution than the NEX-3N. It can shoot video footage at 4K/30p, while the NEX-3N is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k 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 table below summarizes some of the other core capabilities of the Sony A7S II and Sony NEX-3N in connection with corresponding information for a sample of similar cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the A7S II and the NEX-3N is in-body image stabilization (IBIS). The A7S II 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.

The NEX-3N 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 A7S II does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

Concerning the storage of imaging data, both the A7S II and the NEX-3N write their files to SDXC or Memory Stick PRO Duo cards. The A7S II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3N 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 Sony Alpha 7S II 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 A7S II 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 A7S II 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 A7S II was followed by the Sony A7S III. Further information on the features and operation of the A7S II and NEX-3N can be found, respectively, in the Sony A7S II Manual (free pdf) or the online Sony NEX-3N Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony A7S II and the Sony NEX-3N? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Sony Alpha 7S II:

Advantages of the Sony Alpha NEX-3N:

  • More detail: Has more megapixels (16 vs 12MP), which boosts linear resolution by 16%.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (110x62mm vs 127x96mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 358g or 57 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (480 versus 370) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (83 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the A7S II is the clear winner of the match-up (20 : 8 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 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.

A7S II 20:08 NEX-3N

How about other alternatives? Do the specifications of the Sony A7S II and the Sony NEX-3N 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 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 A7S II or the NEX-3N. 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 where reviews by experts come in. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
