Here we are comparing two cameras with different body types: Leica Q, which was introduced in June 2015 is a Large Sensor Compact camera with a 24.0MP Full frame sensor whereas Canon R, which was introduced in September 2018 is a Pro Mirrorless camera with a 30.0MP Full frame sensor.
Comparing an interchangeble lens camera to a fixed lens camera is a bit tricky but we will do our best to make this a fair comparison. Fortunately, you can't go wrong with any of these cameras as we rank them amongst Top 10 cameras in their classes. Leica Q is ranked #2
out of 57 Large Sensor Compact cameras with an overall score of 83 whereas Canon R is ranked #10
out of 38 Pro Mirrorless cameras with an overall score of 91.
Let's have a brief look at the main features of Leica Q and Canon R before getting into our more detailed comparison.
