Ever since the EOS-1Ds Mk III was discontinued a few years ago, many professional photographers, including yours truly longed for a 'megapixel' replacement to this venerable model. Instead Canon has been putting its higher pixel sensor development into the EOS-5D line, culminating in the latest announcement of the EOS-5Ds and EOS-5Ds R 50MP full frame bodies.
The new cameras will not be available till the end of June but speculation has once again turned to whether Canon will bring back the EOS-1Ds model with the latest generation megapixel sensors. I suppose it depends on whether there is a huge demand for the new EOS-5D models to justify the investment but personally I find the ergonomics of the EOS-1D body superior to any camera model out there. Anything over the mid 20MP for a full frame sensor is an 'overkill' for wildlife photography as far as I am concerned. I would rather have higher frame rates, superior AF and high ISO capabilities in the EOS-1D X Mk II coming later this year.
