For all you people who want better AF in the 5D3, what do you mean by better?
- More points, no matter how they perform?
- More f/2.8 and cross-type points? (regardless of how much light and how many total points there are)
- Points that work in less light? (regardless of how many there are and what aperture they are sensitive to)
The "better-AF" is probably the most-read debate about the 5D3 besides the "32+MP vs 18MP high-iso" debate.
For anyone who bought the 5D2 upon release (or within a year), was the AF good for you then? Did it only get worse once the 7D came out? If they come out with 19pt AF and then the 7D2 has 27pt AF, will the 5D3 be useless then too?
Well, more cross-type sensors is the first thing. I hate it when I use 5D2 and many times I couldn't use the outside focus points to focus.
I don't mind if it's gonna be less than 19, but I would want a similar focus system in 7D. Otherwise, I will just snag a used 5D2 when the new 5D3 comes out.
