Canon 20D vs R8

The Canon EOS 20D and the Canon EOS R8 are two digital cameras that were announced, respectively, in August 2004 and February 2023. The 20D is a DSLR, while the R8 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (20D) and a full frame (R8) sensor. The 20D has a resolution of 8.2 megapixels, whereas the R8 provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Canon 20D and the Canon R8 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Size Canon 20D vs Canon R8
Compare 20D versus R8 top
Comparison 20D or R8 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R8 is notably smaller (25 percent) than the Canon 20D. Moreover, the R8 is substantially lighter (40 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the R8 are weather-sealed.

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 Canon BP-511A battery, while the R8 can take 220 images on a single charge of its Canon LP-E17 power pack. The power pack in the R8 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

The price is, of course, an important factor in any camera decision. 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 two cameras under review were launched at the same price and fall into the same market segment. 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. 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. 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 R8 a full frame sensor. The sensor area in the R8 is 154 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 R8 uses a more advanced image processing engine (DIGIC X) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 20D and Canon R8 sensor measures

With 24MP, the R8 offers a higher resolution than the 20D (8.2MP), but the R8 has smaller individual pixels (pixel pitch of 5.98μm versus 6.42μm for the 20D). Yet, the R8 is a much more recent model (by 18 years and 5 months) 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 R8 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R8 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The R8 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 R8 are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 100-204800.

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.

20D versus R8 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 consideration, the R8 offers substantially better image quality than the 20D (overall score 31 points higher). The advantage is based on 2.6 bits higher color depth, 3.7 EV in additional dynamic range, and 2.2 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the R8 has an electronic viewfinder (2360k 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 R8 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 R8 has a higher magnification (0.70x 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 Canon 20D, the Canon R8, and comparable cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The 20D has one, while the R8 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 R8 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 R8 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 Canon R8 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 20D writes its imaging data to Compact Flash cards, while the R8 uses SDXC cards.

It is notable that the R8 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 provide wifi capability.

Studio photographers will appreciate that the Canon 20D (unlike the R8) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The R8 is a recent model that features in the current product line-up of Canon. In contrast, the 20D has been discontinued (but 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 features and operation of the 20D and R8 can be found, respectively, in the Canon 20D Manual (free pdf) or the online Canon R8 Manual.

  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 18 years and 5 months of technical progress since the 20D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the R8 is the clear winner of the contest (27 : 7 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. 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.

20D 07:27 R8

How about other alternatives? Do the specifications of the Canon 20D and the Canon R8 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 incomplete and does no justice, for example, to the way the 20D or the R8 perform in practice. 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 hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
