There appears no way to rotate a Series 7 CPL in proper relation to its angle to the sun when that CPL is dropped into the Series 7 holder of the 24mm. Summilux lens.. There must be some solution to this apparent problem. If not, Series 7 CPLs would seem to be useless even though current B+W and Heliopan versions do exist. I would much appreciate a bit of instructional advice on this.
