There is still some chatter around the web that an EOS 7D Mark III will be coming ahead of Photokina in September. We can safely say that this is not the case and the EOS 7D Mark III will be coming some time in 2019.
If we go by our buyer's guide announcement dates, there are a lot of cameras that still have some time in the lineup before they get replaced.
- The Canon EOS 7D Mark II was announced 1320 days ago, the previous time between the EOS 7D and EOS 7D Mark II was 1637 days.
- The Canon EOS 80D was announced 799 days ago, the previous time between the EOS 70D and EOS 80D was was 961 days.
- The Canon EOS 5DS/5DS R were announced 1176 days ago, since there is no previous versions of these cameras, we'll use the EOS 5D series dates. The time between the EOS 5D Mark III and EOS 5D Mark IV was 1637 days.
We suspect product lifecycles are going to continue to stay the same or increase slightly in the coming years.
