Sigma 17-50mm f/2.8 EX DC OS HSM FLD Issues
Hi. I am new to this forum, so sorry if this has already been asked before. I recently got this sigma lens off eBay and everything seems alright except when I try to use the manual focus ring. For some reason, it seems very sticky and when I turn it, there is this mechanical whirring sound to it that I have concluded comes from this gear that is shown down below. Is there any way to fix this or should I return it? I got it for fairly cheap and other than that, there is nothing else wrong with the lens.
