Canon 20D vs Canon R

The Canon EOS 20D and the Canon EOS R are two digital cameras that were announced, respectively, in August 2004 and September 2018. The 20D is a DSLR, while the Canon R is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (20D) and a full frame (Canon R) sensor. The 20D has a resolution of 8.2 megapixels, whereas the Canon R provides 30.1 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 20D and the Canon EOS R? 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

The physical size and weight of the Canon 20D and the Canon R 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.

Size Canon 20D vs Canon R
Compare 20D versus Canon R top
Comparison 20D or Canon R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R is notably smaller (11 percent) than the Canon 20D. Moreover, the Canon R is markedly lighter (14 percent) than the 20D. It is noteworthy in this context that the Canon R is splash and dust-proof, 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. 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.

Concerning battery life, the 20D gets 700 shots out of its BP-511A battery, while the Canon R can take 370 images on a single charge of its LP-E6N power pack. The power pack in the Canon R can be charged via the USB port, which can be very convenient when travelling.

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 camera comparisons there.

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

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 20D was launched at a markedly lower price (by 35 percent) than the Canon R, 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 20D features an APS-C sensor and the Canon R a full frame sensor. The sensor area in the Canon R is 156 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.

Technology-wise, the Canon R uses a more advanced image processing engine (DIGIC 8) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 20D and Canon R sensor measures

With 30.1MP, the Canon R offers a higher resolution than the 20D (8.2MP), but the Canon R has smaller individual pixels (pixel pitch of 5.36μm versus 6.42μm for the 20D). Yet, the Canon R is a much more recent model (by 14 years) than the 20D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inch or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inch or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inch or 56.9 x 37.9 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.

The Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS R are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.

20D versus Canon R MP

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 consideration, the Canon R offers substantially better image quality than the 20D (overall score 27 points higher). The advantage is based on 2.6 bits higher color depth, 2.5 EV in additional dynamic range, and 1.9 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 also of capturing video footage. The Canon R indeed provides for movie recording, while the 20D does not. The highest resolution format that the Canon R can use is 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Canon R has an electronic viewfinder (3690k 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 Canon R 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 Canon R has a higher magnification (0.76x vs 0.56x), 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 20D and Canon R 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 20D has one, while the Canon R does not. While the built-in flash of the 20D is not very powerful, it can at times be useful as a fill-in light.

The Canon R has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 20D does not have a selfie-screen.

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 Canon R 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 20D writes its imaging data to Compact Flash cards, while the Canon R uses SDXC cards.

 

Connectivity comparison

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 20D and Canon EOS R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 20D does not offer wifi capability.

Studio photographers will appreciate that the Canon 20D (unlike the Canon R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The Canon R is a recent model that features in the current product line-up of Canon. 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 (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary

So what is the bottom line? Which of the two cameras – the Canon 20D or the Canon R – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (139x98mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 110g or 14 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 14 years of technical progress since the 20D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Canon R is the clear winner of the contest (26 : 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 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.

20D 06:26 Canon R

How about other alternatives? Do the specifications of the Canon 20D and the Canon R 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 20D or the Canon R. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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.

The above review scores should be interpreted with care, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
