Canon 7D vs Sony A7S

The Canon EOS 7D and the Sony Alpha A7S are two digital cameras that were revealed to the public, respectively, in September 2009 and April 2014. The 7D is a DSLR, while the A7S is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a full frame (A7S) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Sony provides 12 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 and the Sony Alpha A7S? 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: Canon 7D vs Sony A7S

The physical size and weight of the Canon 7D and the Sony A7S 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 width, height and depth measures are rounded to the nearest millimeter.

Size Canon 7D vs Sony A7S
Compare 7D versus A7S top
Comparison 7D or A7S rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S is notably smaller (27 percent) than the Canon 7D. Moreover, the A7S is substantially lighter (43 percent) than the 7D. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 Canon EF Lens Catalog (7D) and the Sony FE Lens Catalog (A7S). Mirrorless cameras, such as the A7S, 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.

Concerning battery life, the 7D gets 800 shots out of its LP-E6 battery, while the A7S can take 380 images on a single charge of its NP-FW50 power pack. The power pack in the A7S can be charged via the USB port, which can be very convenient when travelling.

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

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 7D was launched at a markedly lower price (by 32 percent) than the A7S, 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: Canon 7D vs Sony A7S

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Canon 7D features an APS-C sensor and the Sony A7S a full frame sensor. The sensor area in the A7S is 158 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 7D and Sony A7S sensor measures

Despite having a smaller sensor, the Canon 7D offers a higher resolution of 17.9 megapixels, compared with 12 MP of the Sony A7S. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 8.45μm for the A7S). Moreover, it should be noted that the A7S is much more recent (by 4 years and 7 months) than the 7D, 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 Canon 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Sony A7S are 21.2 x 14.2 inch or 53.8 x 36 cm for good quality, 17 x 11.3 inch or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inch or 35.9 x 24 cm for excellent quality prints.

The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Sony Alpha A7S are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

7D versus A7S 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 consideration, the A7S offers substantially better image quality than the 7D (overall score 21 points higher). The advantage is based on 1.9 bits higher color depth, 1.5 EV in additional dynamic range, and 2.1 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 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 A7S provides a faster frame rate than the 7D. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 7D vs Sony A7S

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S has an electronic viewfinder (2400k dots), while the 7D 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 A7S has a higher magnification than the one of the 7D (0.71x 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 and Sony A7S 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 7D has one, while the A7S does not. While the built-in flash of the 7D is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The 7D writes its imaging data to Compact Flash cards, while the A7S uses SDXC or Memory Stick PRO Duo cards.

 

Connectivity comparison: Canon 7D vs Sony A7S

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 and Sony Alpha A7S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 7D does not offer wifi capability.

Studio photographers will appreciate that the Canon 7D (unlike the A7S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 7D and the A7S have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the A7S was followed by the Sony A7S II. 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.


Review summary: Canon 7D vs Sony A7S

So what conclusions can be drawn? Is the Canon 7D better than the Sony A7S or vice versa? A synthesis of the relative strong points of each of the models is listed below.

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More affordable: Was introduced into a lower priced category (32 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2009).

ilogo

Advantages of the Sony Alpha A7S:

  • Better image quality: Scores substantially higher (21 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.63x).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x94mm vs 148x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 371g or 43 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Reflects 4 years and 7 months of technical progress since the 7D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A7S is the clear winner of the contest (16 : 9 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 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.

How about other alternatives? Do the specifications of the Canon 7D and the Sony A7S place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 7D and the A7S 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: Canon 7D vs Sony A7S

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
