Canon 7D II vs Sony NEX-7
The Canon EOS 7D Mark II and the Sony Alpha NEX-7 are two enthusiast cameras that were officially introduced, respectively, in September 2014 and August 2011. The 7D Mark II is a DSLR, while the NEX-7 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 20 megapixels, whereas the Sony provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 7D Mark II and the Sony Alpha NEX-7? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 7D II and the Sony NEX-7. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 Sony NEX-7 is considerably smaller (52 percent) than the Canon 7D II. Moreover, the NEX-7 is substantially lighter (56 percent) than the 7D Mark II. It is worth mentioning in this context that the 7D Mark II is splash and dust resistant, while the NEX-7 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (7D Mark II) and the Sony E-Mount Lens Catalog (NEX-7). Mirrorless cameras, such as the NEX-7, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
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-7 was launched at a somewhat lower price (by 25 percent) than the 7D Mark II, which makes it more attractive for photographers on a tight budget. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-7 is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (7D Mark II) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the NEX-7 offers a higher resolution than the 7D Mark II (20MP), but the NEX-7 has smaller individual pixels (pixel pitch of 3.90μm versus 4.10μm for the 7D Mark II). Yet, the 7D Mark II is a much more recent model (by 3 years) than the NEX-7, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
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 Canon 7D II are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The 7D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 7D Mark II has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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-7 offers substantially better image quality than the 7D Mark II (overall score 11 points higher). The advantage is based on 1.7 bits higher color depth, 1.6 EV in additional dynamic range, and 0.1 stops of reduced 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.
| DXO |
|1.||Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|8.||Canon 6D||Full Frame||20.0||5472||3648||1080/30p||23.8||12.1||2340||82|

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 7D Mark II provides a higher frame rate than the NEX-7. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the NEX-7 has an electronic viewfinder (2359k dots), while the 7D Mark II 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the NEX-7 has a higher magnification than the one of the 7D Mark II (0.73x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 7D II and Sony NEX-7 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 7D Mark II, but is missing on the NEX-7 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Canon 7D II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 7D Mark II writes its imaging data to Compact Flash or SDXC cards, while the NEX-7 uses SDXC or Memory Stick PRO Duo cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the NEX-7 only has one slot. The 7D Mark II 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.
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 Canon EOS 7D Mark II and Sony Alpha NEX-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 7D Mark II has a headphone jack, which is not present on the NEX-7 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Studio photographers will appreciate that the Canon 7D II (unlike the NEX-7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the 7D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 7D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the NEX-7 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the NEX-7 from Sony. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what conclusions can be drawn? Is the Canon 7D II better than the Sony NEX-7 or vice versa? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the 7D Mark II is the clear winner of the match-up (16 : 12 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 7D Mark II or the NEX-7 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.
