Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-7 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

The side-by-side display below illustrates the physical size and weight of the Sony NEX-7 and the Sony NEX-6. 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 measures are rounded to the nearest millimeter.

In this particular case, the Sony NEX-7 and the Sony NEX-6 have exactly the same width and height, and, thus, have identically-sized bodies. However, the NEX-6 is markedly lighter (14 percent) than the NEX-7. In this context, it is worth noting that neither the NEX-7 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. 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.

Any camera decision will naturally be influenced heavily by the price. 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-6 was launched at a markedly lower price (by 26 percent) than the NEX-7, 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. 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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.

While the two cameras under review share the same sensor size, the NEX-7 offers a higher resolution of 24 megapixels, compared with 16 MP of the NEX-6. This megapixels advantage translates into a 22 percent gain in linear resolution. On the other hand, these sensor specs imply that the NEX-7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.90μm versus 4.78μm for the NEX-6). Moreover, it should be noted that the NEX-6 is a somewhat more recent model (by 1 year) than the NEX-7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony NEX-6 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-7 has a native sensitivity range from ISO 100 to ISO 16000. The corresponding ISO settings for the Sony Alpha NEX-6 are ISO 100 to ISO 25600 (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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 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

Apart from body and sensor, cameras can and do differ across a variety of features. The NEX-7 and the NEX-6 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2359k dots. The table below summarizes some of the other core capabilities of the Sony NEX-7 and Sony NEX-6 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the NEX-7 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-7 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 NEX-7 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-7 has a microphone port, which is missing on the NEX-6. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the NEX-7 and the NEX-6 have been discontinued, but can regularly be found used on ebay. The NEX-6 was replaced by the Sony A6000, while the NEX-7 does not have a direct successor. Further information on the features and operation of the NEX-7 and NEX-6 can be found, respectively, in the Sony NEX-7 Manual (free pdf) or the online Sony NEX-6 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony NEX-7 and the Sony NEX-6? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Alpha NEX-7:

• More detail: Offers more megapixels (24 vs 16MP) with a 22% higher linear resolution.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Longer lasting: Can take more shots (430 versus 360) on a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in August 2011).

Arguments in favor of the Sony Alpha NEX-6:

• Less heavy: Has a lower weight (by 55g or 14 percent) and is thus easier to take along.
• 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 affordable: Was introduced into a lower priced category (26 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-6 comes out slightly ahead of the NEX-7 (5 : 4 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-7 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 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-7 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

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.

The above review scores should be interpreted 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. 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.
