Perhaps people may comment on this point of view I recently read on the net.
The first thing I did when I purchased my Camera and was to buy UV filters.
Why? (1) To protect my from dust and contaminates. (2) Protection from UV rays. I now have the filters on my two L series . The article on the net I read asked the question why buy top quality and put what will possibly be inferior glass in front of them. I haven’t mentioned the brand name not knowing if that’s allowed. The filters purchased were I believe of reasonable quality about $100.00 dollars per filter. Has the article a valid point to make?
