Exact Fit

Fits Nikon V1 filter thread to KOWA DA10 adapter.


Good quality

As most things from B+W are, this is well made. It is a bit pricey, but given the few options available for mounting 52mm on 40.5mm, this was the best choice.

Sally L  I need a step ring to go on a Nikon 1 v 1 10-30mm kit lens. I know the lens has 40.5mm filter threads. I need to connect it to a spotting scope camera adapter that has 52mm threads. Am I looking for a step up or step down ring?
STEVE H  Hi Sally , You will need a "stepup" ( stepping up from 40.5 to 52mm ) , but keep in mind that the 40.5mm side is" male" threads since it screws into to the lens and the 52mm is "female threads" since it recieves. so if your spotting scope adapter has 52mm "male threads" then it should work for you...hope this helps..........Steve
