17-70 is SDM only (as is the 55/1.4 btw) so no screwdriver option. The problem is, if SDM fails, the body will not allow a fallback to usual screwdrive (and we are angry at PEntax because of that) but a non-SDM body (ist-D serie, K100D) will work with screwdrive just fine.
Oh, the SDM only would of course explain it.
AFAICT the 16-50 had a lot more SDM problems than the 50-135 but this is from memory.
I think it is because 16-50 is simply more frequently used or sought after than 50-135.
As for the lens itself, it isn't very fast to AF but optically this is a pure gem. And yes, not very discrete lens, hood is huge :) I wouldn't sell mine for all the tea in China ;)
Smaller than 80-200/2.8 yet, methinks.
