Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 7D Mark II and the Sony Alpha SLT-A58? 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 physical size and weight of the Canon 7D II and the Sony A58 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 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 A58 is notably smaller (27 percent) than the Canon 7D II. Moreover, the A58 is substantially lighter (46 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 A58 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A58 was launched at a markedly lower price (by 67 percent) than the 7D 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.
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. 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 an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A58 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.
Despite having a smaller sensor, the Canon 7D II offers a higher resolution of 20 megapixels, compared with 19.8 MP of the Sony A58. 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 4.10μm versus 4.31μm for the A58). However, it should be noted that the 7D Mark II is a somewhat more recent model (by 1 year and 6 months) than the A58, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
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 SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A58 has a markedly higher DXO score than the 7D Mark II (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.7 EV in additional dynamic range, and 0.5 stops of reduced 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.
|Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|Canon 6D||Full Frame||20.0||5472||3648||1080/30p||23.8||12.1||2340||82|
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 7D Mark II provides a higher frame rate than the A58. 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 variety of features. For example, the A58 has an electronic viewfinder (1440k 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 7D Mark II has a higher magnification than the one of the A58 (0.63x vs 0.57x), 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 A58 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 A58 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 A58 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 A58 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 A58 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 SLT-A58 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 A58 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 A58) 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 A58 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the A58 was succeeded by the Sony A68. 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 how do things add up? Is the Canon 7D II better than the Sony A58 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

- More heavily discounted: Has been on the market for longer (launched in February 2013).
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 (19 : 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 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 7D Mark II or the A58. 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 expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
