Filter Ring Stepping

Filter Ring Stepping
What polarizing fliters will fit my 18-200mm Sigma lens?

I’m looking for a polarizer filter for my 18-200mm lens and frankly- the lens dimention info baffels me! Does anyone know which will fit this lens or which step up rings will work on it?

Also- will I need different filters for other lenses (such as 50mm f/1.8) or will I be able to get an adapter and use the same filters on both? thanks for your time!

You’ll want a 62mm circular polarizer. , yes.. the 50mm 1.8 takes a 48mm filter… read the ring around the end of your lens, it will tell you what size filters your lens accepts.
Stepping a 48mm to 62mm would be pretty impossible…
