Canon 5D versus Sony A7

The Canon EOS 5D and the Sony Alpha A7 are two digital cameras that were officially introduced, respectively, in August 2005 and October 2013. The 5D is a DSLR, while the A7 is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The Canon has a resolution of 12.7 megapixel, whereas the Sony provides 24 MP.

Body comparison

The physical size and weight of the Canon 5D and the Sony A7 are illustrated in the side-by-side display below. 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. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 5D – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 is notably smaller (30 percent) than the Canon 5D. Moreover, the A7 is substantially lighter (47 percent) than the 5D. 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D) and the Sony FE Lens Catalog (A7). Mirrorless cameras, such as the A7, 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7 was launched at a markedly lower price (by 48 percent) than the 5D, 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. 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 are more costly to manufacture and tent 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 A7 is 1 percent smaller. 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.

Canon 5D and Sony A7 sensor measures
Sensor size

Despite having a slightly smaller sensor, the A7 offers a higher resolution of 24 megapixel, compared with 12.7 MP of the 5D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.97μm versus 8.25μm for the 5D). However, it should be noted that the A7 is much more recent (by 8 years and 2 months) than the 5D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

5D versus A7 MP
Sensor resolution

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 consideration, the A7 offers substantially better image quality than the 5D (overall score 19 points higher). The advantage is based on 1.9 bits higher color depth, 3.1 EV in additional dynamic range, and 0.7 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 can also record movies. The A7 indeed provides for movie recording, while the 5D does not. The highest resolution format that the A7 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 has an electronic viewfinder (2400k dots), while the 5D 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 table below summarizes some of the other core capabilities of the Canon 5D and Sony A7 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Advantages of the Canon EOS 5D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Longer lasting: Can take more shots (400 versus 340) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2005).

logo checkmark

Reasons to prefer the Sony Alpha A7:

  • More detail: Has more megapixels (24 vs 12.7MP), which boosts linear resolution by 37%.
  • Better image quality: Scores substantially higher (19 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 (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (127x94mm vs 152x113mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 421g or 47 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
  • More modern: Reflects 8 years and 2 months of technical progress since the 5D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7 is the clear winner of the contest (16 : 4 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.

5D 04:16 A7

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 5D or the A7 handle or perform in practice. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 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.
