The sports version has it's strengths in being robust, weather sealed, dust sealed. And bloody heavy. Without tripod it's challenging to hand-hold it. Are you sure you need a zoom? I've no idea how fast it will AF, but what I saw from other Canon lenses in front of Sony cameras, I wouldn't be afraid - even if it's bit slower, what good is speed for if AF is typically phase detection limited and although possibly faster, less precise?
Buying a lens now and the adapter much later means, you have to wait possibly for quite a while - the difference between Sigma's introduction dates and delivery dates can be considerably long. I waited 8 months form introduction to delivery of the Sports version.
