Body comparison

The physical size and weight of the Sony A7S and the Canon 5D Mark II 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 Sony A7S vs Canon 5D Mark II
Compare A7S versus 5D Mark II top
Comparison A7S or 5D Mark II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 5D Mark II is considerably larger (45 percent) than the Sony A7S. Moreover, the 5D Mark II is substantially heavier (74 percent) than the A7S. 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. 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 Sony FE Lens Catalog (A7S) and the Canon EF Lens Catalog (5D Mark II). Mirrorless cameras, such as the Sony A7S, 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 A7S gets 380 shots out of its Sony NP-FW50 battery, while the 5D Mark II can take 850 images on a single charge of its Canon LP-E6 power pack. The power pack in the A7S can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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

Any camera decision will obviously take relative prices into account. 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 A7S was launched at a markedly lower price (by 29 percent) than the 5D Mark II, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 a full frame sensor, but their sensors differ slightly in size. The sensor area in the 5D Mark II is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7S and Canon 5D Mark II sensor measures

With 21MP, the 5D Mark II offers a higher resolution than the A7S (12MP), but the 5D Mark II has smaller individual pixels (pixel pitch of 6.41μm versus 8.45μm for the A7S). Yet, the A7S is a much more recent model (by 5 years and 6 months) than the 5D Mark II, 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 5D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark II for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Sony A7S are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.

The Sony Alpha A7S has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Canon EOS 5D Mark II are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.

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.

A7S versus 5D Mark II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A7S has a notably higher overall DXO score than the 5D Mark II (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.2 bits higher color depth, 1.3 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A7S provides a higher frame rate than the 5D Mark II. It can shoot video footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

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 5D 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 viewfinder in the A7S offers a wider field of view (100%) than the one in the 5D Mark II (98%), so that a larger proportion of the captured image is visible in the finder. The table below summarizes some of the other core capabilities of the Sony A7S and Canon 5D Mark II in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the 5D Mark II, but is missing on the A7S 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 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 A7S writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 5D Mark II uses Compact Flash cards.

It is notable that the A7S has a headphone jack, which is not present on the 5D Mark II 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 5D Mark II (unlike the A7S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the A7S and the 5D Mark II have been discontinued, but can regularly be found used on ebay. The 5D Mark II was replaced by the Canon 5D Mark III, while the A7S was followed by the Sony A7S II. Further information on the features and operation of the A7S and 5D Mark II can be found, respectively, in the Sony A7S Manual (free pdf) or the online Canon 5D Mark II Manual.

Review summary

So how do things add up? Is there a clear favorite between the Sony A7S and the Canon 5D Mark II? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Sony Alpha A7S:

  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (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.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (5 vs 3.9 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x94mm vs 152x114mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 361g or 42 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of 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 affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
  • More modern: Reflects 5 years and 6 months of technical progress since the 5D Mark II launch.

ilogo

Reasons to prefer the Canon EOS 5D Mark II:

  • More detail: Has more megapixels (21 vs 12MP), which boosts linear resolution by 32%.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (850 versus 380) out of a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the A7S is the clear winner of the match-up (18 : 6 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.

A7S 18:06 5D Mark II

How about other alternatives? Do the specifications of the Sony A7S and the Canon 5D Mark II 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A7S or the 5D Mark II perform in practice. 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.

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

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
