Technology tends to have a short lifespan, but the Canon EOS R6 series is so popular in Japan that both of the older models are in the top three for used camera sales.
The data comes from a popular Japanese camera buy-and-sell app, Minna Camera, which recently tallied the most popular cameras sold on the app for the month of June. The list is led by the Canon EOS R6 Mark II, followed by the Sony ZV-E10 and the original Canon EOS R6.
