Body comparison

The physical size and weight of the Sony NEX-6 and the Sony NEX-3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth 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.

Size Sony NEX-6 vs Sony NEX-3
Compare NEX-6 versus NEX-3 top
Comparison NEX-6 or NEX-3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-3 is notably smaller (10 percent) than the Sony NEX-6. Moreover, the NEX-3 is markedly lighter (14 percent) than the NEX-6. In this context, it is worth noting that neither the NEX-6 nor the NEX-3 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. 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.

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-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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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 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-6 and Sony NEX-3 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). In this context, it should be noted, however, 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 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 NEX-3 are 23 x 15.3 inches or 58.3 x 38.8 cm for good quality, 18.4 x 12.2 inches or 46.7 x 31 cm for very good quality, and 15.3 x 10.2 inches or 38.9 x 25.9 cm for excellent quality prints.

The Sony Alpha NEX-6 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (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.

NEX-6 versus NEX-3 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 NEX-6 has a notably higher overall DXO score than the NEX-3 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NEX-6 provides a higher video resolution than the NEX-3. It can shoot video footage at 1080/60i, while the NEX-3 is limited to 720/30p.

Feature comparison

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 adjacent table lists some of the other core features of the Sony NEX-6 and Sony NEX-3 along with similar information for a selection of comparators.

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 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 NEX-6 does not have a selfie-screen.

Concerning the storage of imaging data, both the NEX-6 and the NEX-3 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.

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

Both the NEX-6 and the NEX-3 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 features and operation of the NEX-6 and NEX-3 can be found, respectively, in the Sony NEX-6 Manual (free pdf) or the online Sony NEX-3 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Sony NEX-6 or the Sony NEX-3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Sony Alpha NEX-6:

  • More detail: Offers more megapixels (16 vs 14MP) with a 7% higher linear resolution.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.6 bits more color depth).
  • More dynamic range: Captures a larger spectrum 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 composition and settings control.
  • Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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.


Advantages of the Sony Alpha NEX-3:

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

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-6 is the clear winner of the match-up (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 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.

NEX-6 11:04 NEX-3

How about other alternatives? Do the specifications of the Sony NEX-6 and the Sony NEX-3 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the NEX-6 and the NEX-3 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
