Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-6 and the Canon EOS 6D? 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-6 and the Canon 6D. 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 width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 6D is considerably larger (100 percent) than the Sony NEX-6. Moreover, the 6D is substantially heavier (123 percent) than the NEX-6. It is noteworthy in this context that the 6D is splash and dust-proof, while the NEX-6 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 E-Mount Lens Catalog (NEX-6) and the Canon EF Lens Catalog (6D). Mirrorless cameras, such as the Sony NEX-6, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the NEX-6 gets 360 shots out of its Sony NP-FW50 battery, while the 6D can take 1090 images on a single charge of its Canon LP-E6 power pack.

The price is, of course, an important factor in any camera decision. 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 52 percent) than the 6D, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony NEX-6 features an APS-C sensor and the Canon 6D a full frame sensor. The sensor area in the 6D is 137 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 20MP, the 6D offers a higher resolution than the NEX-6 (16MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 4.78μm for the NEX-6) due to its larger sensor. 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 Canon 6D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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-6 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon EOS 6D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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.

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 consideration, the 6D has a markedly higher DXO score than the NEX-6 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.1 bits higher color depth, 1 EV of lower dynamic range, and 1.2 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the NEX-6 provides a higher frame rate than the 6D. It can shoot video footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the NEX-6 has an electronic viewfinder (2359k dots), while the 6D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the NEX-6 offers a wider field of view (100%) than the one in the 6D (97%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the NEX-6 has a higher magnification (0.73x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Sony NEX-6 and Canon 6D 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 6D 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-6 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 6D uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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-6 and Canon EOS 6D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The NEX-6 does not feature such a mic input.

Travel and landscape photographers will find it useful that the 6D has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the NEX-6 and the 6D have been discontinued, but can regularly be found used on ebay. The NEX-6 was replaced by the Sony A6000, while the 6D was followed by the Canon 6D Mark II. Further information on the features and operation of the NEX-6 and 6D can be found, respectively, in the Sony NEX-6 Manual (free pdf) or the online Canon 6D Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony NEX-6 and the Canon 6D? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Sony Alpha NEX-6:

• More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 97%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.71x).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (10 vs 4.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (120x67mm vs 145x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 425g or 55 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (52 percent cheaper at launch).

Arguments in favor of the Canon EOS 6D:

• More detail: Has more megapixels (20 vs 16MP), which boosts linear resolution by 12%.
• Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Longer lasting: Gets more shots (1090 versus 360) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier geotagging: Features an internal GPS sensor to log localization data.

If the count of relative strengths (bullet points above) is taken as a measure, the NEX-6 emerges as the winner of the contest (12 : 10 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 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-6 and the Canon 6D 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the NEX-6 and the 6D 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
