Alternate filter attachment methods
You can use any of three types of
adapter rings to attach glass filters to
the MP 4 lenses:
•
A set-screw ring slips loosely over the
front of the lens mount and is
held in place by a set-screw
•
A slip-on ring slips tightly over the
front of the lens mount and is held
in place by friction
•
A threaded ring screws into the
front mounting threads of the lens
A step-up ring enables you to use
•
the Series 6 filters with the 35mm
and 17mm lenses as well as with
the other MP 4 lenses.
