Hello all,

How much dust can accumulate on a DSLR mirror before it starts to cause image issues? I ask because i've always been told to NEVER touch the mirror. Using a rocket blower seems to have no effect on the dust on the mirror.

Thanks!

(I mistakenly offered advice about cleaning SENSORS when I realize the OP was speaking about MIRRORS.)
