my lens is Tamron 17-50 F2.8 for Canon.
(I did not find any suitable place to post, so if any moderator can please move this thread to appropriate section please)
My lens had some spots in front element. I was watching a video on youtube on how to remove the front element and clean it. It looked easy. but i when opening that front ring, i broke it.
Please have a look at this picture, and tellme what does it call?
I have searched all over the internet for this but couldn't find any help.
If anyone of you please share a link where i can find one on Ebay or Aliexpress. that would be great.
