Now I know the "should my expensive lens have cheap glass on the front?" is an age old question that will never be agreed upon and ends up down to preference. What I'm interested in is the UV vs non-UV perspective.
I'm looking to get a Canon 70-200 L f/4 IS in the next few weeks and obviously as soon as it comes out of the box I want to protect my baby. I may over time decide that a filter on the front to protect it isn't needed but I'll definitely want one to start with. What I want to know, and can't seem to find online (as it returns arguments about filter-or-not) is: does the L lens need UV protection?
The L lenses have a lot of complicated glass in them with various coatings to that glass, and is that arrangement, or any specific coatings, already designed to cut out any problems caused by UV?
I am deciding on whether to get a Hoya Pro protector filter or UV filter, but if the L lens is already designed to remove problems caused by UV I would prefer to have the clear filter to remove any potential problems caused by another UV limiting element. I know the benefits a UV filter can give to a normal camera/lens setup so no need to be letting me know the pros and cons of that.
