I am picking up mine in 3 days.
This camera is going to open doors for me with its fast frame rate and super AF. I have been shooting sports with my NX1 and my Sony A7r2 but now, for action shots, I will replace both of those with the amazing a6300.
It is going to be super with the 70-200/4 or the 70-200 GM.
I'll be trying it right away with my 70-400 G2 and Le-ae3 adapter.
It should also be first rate with the Sigma MC-11 and some of the insane Sigma glass.
Early low light video tests look unexpectedly strong as well.
The a6300 is, in some ways, more of an all arounder than even the A7r2.
Pity they didn't make it a hair bigger and put in IBIS.
