HS10 for indoor stadium movies at long end ? (Paralympics)

Hi everyone

I somehow got Paralympic tickets for Stratford this saturday night 8th sept.

(I have J1 + 30-110 for action
Nex5 + 50/1.4 & 85/2 for shallow dof).

Just want a long bridge for movies.

Is HS10 decent at 700mm for movies inside the stadium.
How is vibration control & video quality at 700mm

Thank you.
