I am considering purchasing a Canon sl2. I notice that it has the same 9 point 1 cross type auto focus system that has been used for many many years.
My current Canon t3 uses this auto-focus system.
I have read statements on forums that suggest because the canon sl2 has a much more powerful processor in the Digic 7, that its autofocus will actually perform better than older cameras that also utilise, seemingly, the same 9 point autofocus system.
Is this true? If so, in what way could the same autofocus system benefit from a faster processor?
