This metal adapter ring fits into our 7dayshop square filter holder and then the holder can be screwed onto your lens thereby allowing use of 7dayshop square filters.
This adapter ring fits lenses with a filter size of Φ 82mm. You may need different adapter rings for different lenses but you can use the same holder and filters of course.
To check the size of the adapter ring you need (the filter size of your lens) then please look for a symbol like this "Φ " which is normally on the front of the lens as you look into it. Alternatively look at the reverse of your lens cap and it will normally show the "??mm" filter size.
