[Leica] Using polarizers w/Macro Elmarit

["Anderson, Ferrel E" <AndersonF@ria.army.mil>]

The original Macro Elmarit takes the Serie VIII filters in the lens hood, or
E60 screw-in filters directly on the lens..  If you want to use E55 filters
on the Macro Elmarit, use the E60 to E55 step down ring, which is available
from Tiffen, and perhaps other suppliers.  I don't know if the 60 to 55
solution results in vignetting, but this has to be checked out.  The lens
hood can still be used, but must be removed in order to turn the polarizer
filter.  Your choice might be influenced by other factors, such as to
whether your other lenses use E55 or E60 filters?  The 100 APO Macro takes
E60 filters.
