I'm fairly new to photography and I only own two lenses (one with a 52 mm diameter and another with a 58 mm diameter). I want to buy a good polarizing filter but I don't want to buy one for each lens. From what I've read online, stepup adapter rings can be used to mate larger filters with smaller lenses.
Since I don't know the diameter of any lenses I might buy in the future, I'm planning on buying a large filter (~77 mm) and then buying adapters for each of my lenses. Is there any disadvantage to using a stepup adapter with an oversized filter? Is this a good strategy?
