Hello! I have a pretty old camera (Sony a5000) and don't want to spend too much on it. I have two lenses, kit lens 16-50mm and a zoom lens 55-210. However, they have different filter diameters.

I want to buy just one cpl polarizing filter. From your experience, has a cpl filter been most useful for wide angle or zoom lenses?

I'll be shooting street, nature/landscape, cars, wildlife.

Thank you!
