| I have shot musicals and dance with the sigma APO 70-200 F2.8 EX (that's right, first version, no DG coating on rear element, and screw drive)
Honestly the shutter makes more noise than focusing.
You will not be able to set at infinity from my experience, and focusing can be challenging at times depending on stage lighting, and clearly a flash or focusing beam is out of the question.
If you are really concerned about focusing noise, go MF with a split image and 1-2 fst primes. |
