SN25T1 ND1000 Square Filter 100x100mm + Metal Holder + 8pcs Adapter Rings For DSLR

SKU: SKU.1596

Q
Why doesn't it have a 55mm ring?
Answer Question
A
I think they went with common adapter sizes based on popular lens types, you can get a set of step up/down rings that can be adapted to your 55mm filter diameter. I think they sell for like $15 or something like that. You're going to want to get a 55mm step up to 58 mm ring
