Canon EOS-1D X Mark III Undergoing Field Testing?

Canon Eos-1d X Mark Ii
View Post

Rumor has it Canon has started to field test the replacement for the Canon EOS-1D X Mark II.

The EOS-1D X Mark II was released in 2016 so it seems a bit early for an announcement. However, being this the top professional Canon DSLR it wouldn’t be strange if Canon spends a lot of time testing it.

Our bet is Canon will announce the Canon EOS-1D X Mark III before the Olympic games in 2020. So far no specifications have leaked.

Stay tuned.
