As we already reported before, the upcoming Canon EOS-1D X Mark III is in testing by a small number of photographers and/or engineers. It seems that the 1D series high-end DSLR cameras have a product lifecycle of around 4 years. The Canon EOS-1D X Mark II was announced on February 1st, 2016, now it is three years old. So we are likely to see 1D X Mark III to be announced in Q4 of 2019 to Q2 of 2020. Just ahead of 2020 Summer Olympic games in Tokyo, Japan.
Currently, there is no info about upcoming Canon EOS R Pro/high-end full frame mirrorless camera. We don’t yet whether EOS-1D X Mark III will be the last 1D series DSLR camera and replaced by upcoming Canon EOS R/High-end. We expect to see more rumors and news about EOS R Pro/High-end after EOS-1D X Mark III announced.
