Hi - I have a new Tamron SP 150-600 G2 lens and thinking of moving away from my Canon 5D MK ii. For the Canon brand the 7D MK ii seems to be a favorite choice for bird/wildlife photography with a lot of professionals using it. I was thinking about getting the 1.4 teleconverter but I think between the two - despite the price difference - the 7D would be a more logical choice. Then I started reading about the EOS R and the 5DSR which are both really impressive although a lot more money. Given that I would probably not fork out the $$ for a 5D MK iv or a 1DX wondering if there are any thoughts on going mirrorless as opposed to the 7D MK ii. I understand the differences but just not sure whether to jump now or save up for the mirrorless - and then still need the teleconverter.
