Body comparison: Sony A7 III vs Canon 20D
An illustration of the physical size and weight of the Sony A7 III and the Canon 20D is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 Canon 20D is notably larger (25 percent) than the Sony A7 III. Moreover, the 20D is markedly heavier (18 percent) than the A7 III. It is worth mentioning in this context that the A7 III is splash and dust resistant, while the 20D 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. 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 Sony FE Lens Catalog (A7 III) and the Canon EF Lens Catalog (20D). Mirrorless cameras, such as the Sony A7 III, 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 A7 III gets 610 shots out of its NP-FZ100 battery, while the 20D can take 700 images on a single charge of its BP-511A power pack. The power pack in the A7 III 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.

Any camera decision will obviously take relative prices into account. 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 20D was launched at a somewhat lower price (by 25 percent) than the A7 III, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
Sensor comparison: Sony A7 III vs Canon 20D
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.
Of the two cameras under consideration, the Sony A7 III features a full frame sensor and the Canon 20D an APS-C sensor. The sensor area in the 20D is 60 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the A7 III offers a higher resolution than the 20D (8.2MP), but the A7 III has smaller individual pixels (pixel pitch of 5.94μm versus 6.42μm for the 20D). However, the A7 III is a somewhat more recent model (by 13 years and 6 months) than the 20D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the A7 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The A7 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Sony Alpha A7 III has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Canon EOS 20D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200..
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 review, the A7 III provides substantially higher image quality than the 20D, with an overall score that is 34 points higher. This advantage is based on 3.1 bits higher color depth, 3.7 EV in additional dynamic range, and 2.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The A7 III indeed provides movie recording capabilities, while the 20D does not. The highest resolution format that the A7 III can use is 4K/30p.
Feature comparison: Sony A7 III vs Canon 20D
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 III has an electronic viewfinder (2359k dots), while the 20D 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 A7 III offers a wider field of view (100%) than the one in the 20D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7 III has a higher magnification (0.78x vs 0.56x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Sony A7 III, the Canon 20D, and comparable cameras.

One feature that differentiates the A7 III and the 20D is in-body image stabilization (IBIS). The A7 III reduces the risk of handshake-induced blur with all attached lenses, while the 20D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the A7 III features an 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 A7 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 20D uses Compact Flash cards. The A7 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 20D only has one slot.
Connectivity comparison: Sony A7 III vs Canon 20D
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 Sony Alpha A7 III and Canon EOS 20D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 III offers wifi support, while the 20D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Canon 20D (unlike the A7 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The A7 III is a recent model that features in the current product line-up of Sony. In contrast, the 20D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 20D was succeeded by the Canon 30D. Further information on the two cameras, as well as related accessories, can be found on the Sony and Canon websites.

If the number of relative strengths (bullet points above) is taken as a guide, the A7 III is the clear winner of the match-up (28 : 8 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 before making a camera decision.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the A7 III and the 20D in practical situations. 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.

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. 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.
