Originally posted by mee My 16-50mm just came back from Precision where (among other things) they replaced the SDM.. now it squeaks! It used to not squeak. It is quite audible.. and it sounds a little jangly too when focusing.
And my 50-135mm doesn't squeak. However the 16-50mm is on it's way back to Precision to (among other things) resolve the squeak!
If you just bought a lens brand new doing this.. I'd suggest to instantly RMA that sucker back to the seller and get a different copy.
Chirpy chirpy... It's a shame because it's a sharp copy...
Yes on the "jangly" too! The 16-50 is solid, no clunk clunk when I shake it, not so the 50-135! Like something is loose inside.
Too bad B&H started using those non-reusable boxes!
