How to Adjust Series 7 CPL at 90 degrees to the Sun?

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.

I have no answers to your question, sorry, but I’m curious to see the pictures you will take.

Generally speaking, a polarizer on a wide is unusual, but sometimes results are very interesting

I understand your point of view re use of CPLs on wide-angle lenses, but 24mm. lens is not super, super wide. It sort of straddles the dividing line. The polarized results of that focal length largely depend on the photo's content, time of day, angle of polarization, what is acceptable re one's photographic purpose, etc. Thanks for your response.

Well, a 24 mm lens will have an angle of view of 84º. That means that the effect of the polarizer will range from 0% to 100% if the sun is at 45º, and from 50% to 100% to 50% if it is exactly at 90º That is a massive density difference in a blue sky, for instance. Made worse because it is exactly opposite to vignetting, which our eyes have been trained to accept as "normal".

Yes too wide a lens for pola.  PS  LR  Cap one all have better ways to deal with darkening skies.

 

Side note,  certain R lenses that used series had a rubber covered wheel built into hood to provide rotation.  Only Leica filters worked,  third party were a shade small and there was not enough friction.

 

If you still want to try,  maybe a step up ring could be used.  This usually results in make the hood not fit.  Also rotating to require maximum exposure will be at 90 degrees.
