Canon 20D vs Canon 5DS R

Here is a extensive assessment of the Canon 20D versus Canon 5DS R, both Advanced DSLR cameras and both of them are sold by Canon. There exists a sizeable gap among the resolutions of the 20D (8MP) and 5DS R (51MP) and the 20D (APS-C) and 5DS R (Full frame) provide different sensor sizes.

The 20D was revealed 11 years prior to the 5DS R and that is a fairly large gap as far as camera technology is concerned. Both of these cameras have the same body design (Mid-size SLR).

Before delving into a detailed comparison, here is a simple introduction of how the 20D scores versus the 5DS R with regard to portability, imaging, features and an overall rating.

The following is a sample of the gallery pictures for Canon EOS 20D and Canon EOS 5DS R. The full galleries are available at Canon 20D Gallery and Canon 5DS R Gallery.

If you're intending to carry your camera, you are going to need to think about its weight and volume. The Canon 20D provides external dimensions of 144mm x 106mm x 72mm (5.7" x 4.2" x 2.8") along with a weight of 770 grams (1.70 lbs) while the Canon 5DS R has sizing of 152mm x 116mm x 76mm (6.0" x 4.6" x 3.0") accompanied by a weight of 930 grams (2.05 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will change based on the lens you use at the time. The following is a front view dimension comparison of the 20D vs the 5DS R.

Considering dimensions and weight, the portability score of the 20D and 5DS R is 59 and 55 respectively.

More often than not, it is very tough to picture the gap in sensor sizing purely by looking through a spec sheet. The graphic below may give you a far better sense of the sensor sizes in the 20D and 5DS R.

Clearly, each of the cameras provide different resolutions and different sensor sizing. The 20D having a smaller sensor is going to make getting bokeh harder and the Canon 5DS R will render extra detail because of its extra 43 Megapixels. Greater resolution will let you crop images more aggressively. The older 20D will be behind with regard to sensor tech.
