Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-3 and the Sony Alpha NEX-6? 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: Sony NEX-3 vs NEX-6

The physical size and weight of the Sony NEX-3 and the Sony NEX-6 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The NEX-3 can be obtained in three different colors (black, silver, red), while the NEX-6 is only available in black.

Comparison NEX-3 or NEX-6 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-6 is notably larger (11 percent) than the Sony NEX-3. Moreover, the NEX-6 is markedly heavier (16 percent) than the NEX-3. In this context, it is worth noting that neither the NEX-3 nor the NEX-6 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

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

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 NEX-3 was launched at a markedly lower price (by 40 percent) than the NEX-6, 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: Sony NEX-3 vs NEX-6

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony NEX-3 and Sony NEX-6 sensor measures

While the two cameras under review share the same sensor size, the NEX-6 offers a higher resolution of 16 megapixels, compared with 14 MP of the NEX-3. This megapixels advantage translates into a 7 percent gain in linear resolution. On the other hand, these sensor specs imply that the NEX-6 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.78μm versus 5.11μm for the NEX-3). However, it should be noted that the NEX-6 is much more recent (by 2 years and 4 months) than the NEX-3, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Sony NEX-6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-6 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inch or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inch or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inch or 41.6 x 27.6 cm. The corresponding values for the Sony NEX-3 are 23 x 15.3 inch or 58.3 x 38.8 cm for good quality, 18.4 x 12.2 inch or 46.7 x 31 cm for very good quality, and 15.3 x 10.2 inch or 38.9 x 25.9 cm for excellent quality prints.

The Sony Alpha NEX-3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Sony Alpha NEX-6 are ISO 100 to ISO 25600 (no boost).

NEX-3 versus NEX-6 MP

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. Of the two cameras under consideration, the NEX-6 has a markedly higher DXO score than the NEX-3 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.6 bits higher color depth, 1.1 EV in additional dynamic range, and 0.3 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the NEX-6 provides a better video resolution than the NEX-3. It can shoot movie footage at 1080/60i, while the NEX-3 is limited to 720/30p.

 

Feature comparison: Sony NEX-3 vs NEX-6

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the NEX-6 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The table below summarizes some of the other core capabilities of the Sony NEX-3 and Sony NEX-6 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The NEX-6 has one, while the NEX-3 does not. While the built-in flash of the NEX-6 is not very powerful, it can at times be useful as a fill-in light.

The NEX-3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the NEX-6 does not have a selfie-screen.

Concerning the storage of imaging data, both the NEX-3 and the NEX-6 write their files to SDXC or Memory Stick PRO Duo cards. The NEX-6 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Sony NEX-3 vs NEX-6

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-3 and Sony Alpha NEX-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-6 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the NEX-3 does not offer wifi capability.

Both the NEX-3 and the NEX-6 have been discontinued, but can regularly be found used on eBay. The NEX-3 was replaced by the Sony NEX-3N, while the NEX-6 was followed by the Sony A6000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.


Review summary: Sony NEX-3 vs NEX-6

So how do things add up? Is the Sony NEX-3 better than the Sony NEX-6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Sony Alpha NEX-3:

  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Less heavy: Is lighter (by 48g or 14 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in May 2010).


Advantages of the Sony Alpha NEX-6:

  • More detail: Has more megapixels (16 vs 14MP), which boosts linear resolution by 7%.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
  • Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 2 years and 4 months of technical progress since the NEX-3 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the NEX-6 is the clear winner of the contest (11 : 4 points). 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 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.

NEX-3 04:11 NEX-6

How about other alternatives? Do the specifications of the Sony NEX-3 and the Sony NEX-6 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 says little about, for example, the shooting experience and imaging performance of the NEX-3 and the NEX-6 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: Sony NEX-3 vs NEX-6

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
