I already knew the Canon EF 24-70 f/2.8L II was going to have plastic threads where filters attach. I do not use a UV filter to protect the front element. I've got drops and spills insurance for that. However, my new lens came with a very inexpensive set of Pro Optic filters (UV, ND, Circ. Pol.) thrown in free by Adorama. I'll never use them, or so I thought.
I'm no plastics chemist. I've no idea how tough the plastic threads or the edge of that part of the lens is. I just thought I would try something to protect that edge and those threads beyond what the lens hood offers..
I took the UV Haze filter, wrapped it in a paper towel, placed it in a ziplock bag and used a small hammer to shatter the glass of the filter. I then removed the metal filter ring from the ziplock bag and cleaned all remaining glass from it and screwed the now filter-less metal ring onto the filter threads of my lens. Voila!
Just a little peace of mind and added protection. I think so anyway.
