I like the idea that they have the auto focus buttons on the lens, hopefully, they may be like the Nikon buttons and have preset focus points, to be able to set a pre-set point is a BIG advantage in sports togging, lets hope this is part of it, I also wouldn't mind if it is just an AF button ( I suppose) makes life a bit easier when shotting sport in rougher conditions, or cold, half press can be hard then.
Very much looking forward to this lens..
Anybody know if the New TC 1.4 TELECONVERTER is a FF or not?????

On closer inspection of the Pics of the Lens, it says, "preset"...so, very happy
I think there is one button that says Preset, but it does not look like it is one of the four focus buttons. I'm looking forward to hearing more on the functionality of all the buttons. Thanks to everyone that has posted info here.
