I have the new M version of the Voigtlander 12mm lens with the 67mm filter thread. With the first LTM version there was a 77mm filter adapter that allowed the use of center filters for vignetting control. With the new M version and the 67mm filter thread what options are there for using center filters. I am considering going back to the ltm version just for the ability to use center filters.
