I have the Schneider 240mm f/4.5 LS Blue Ring lens. The lens is a 86mm filter size and a build-in lens hood. The lens hood extends out over the lens just enough so that the Lee 86mm adapter for the 100mm filters will not work. Tried the Lee SW150 86mm screw-on adapter and the same problem.
Looks like a filter adapter with a deeper filter adapter is required or the hood will have to be removed.
Normal screw-on filters will work fine since they fit inside the lens hood.
Has anyone got any ideas on a solution. Thanks.
