According to Flickr, the most popular camera in the world isn’t even a camera! It is iPhone 11, which came out as the most popular camera in 2019, beating all the DSLR and Mirrorless System cameras.
In the last few years, there are some big pretty incredible camera released such as Sony A7 IV, Nikon Z9 and Canon EOS R5, but it is sadly that the price point of these cameras make them out of reach for a lot of people.
Canon EOS 5D Mark IV (Amazon/ B&H), which was released in 2016 is still the world’s most popular camera.
