A UV filter for your lens.20 May 2021
[photography] A quick note, I was rather late in getting UV filters for all of my lenses. They are a lot less expensive than lenses, and many people use them as the first layer of protection from scratches amd damage for their lens.
An added bonus, since the filter is flat, while the lens is curved, these filters seem to pick up a lot less dust and blowing it off with an air blower goes a lot faster than with the lens.
To purchase, you will need to know the size of the lens. This is indicated on the lens with an ‘O’ with a slash through it, with a number.
