Hmmm, presumably since you are concerned about focus noise, the
classical concert is indoors (?). If so, the light level is likely to force the
use of the inadequately-fast f5.6 aperture at the long end of the zoom
range, and that zoom is unlikely to be very sharp at the long end at
that aperture (wide-open)... A good 28mm f2.8, 35mm f2, 50mm f1.8,
85mm f2, 135mm f2.8, 180mm f2.8, *or* 200mm f4 would serve better
than this zoom (or any other zoom, maybe short of a 70-210mm or
80-200mm f2.8...) - or choose a couple of the primes for variety.
Light levels are generally very low in classical concerts...
