Re: Mamiya 120mm Macro for portraits

It is a supplemental lens that goes on the front of your primary lens like a
filter (many are screw-ons but some are bayonet types).  there are three
often used diopter strengths +1, +2, and +3.  They serve as a cheap way of
acquiring macro effects.  They are often referred to as close-up lenses
because depending on the strength they enable one to get within two feet of
the subject and shoot a close up ( potentially good for insects and the like
but not too good for people unless you are making a pimple the subject of
the frame).  The major disadvantage over a true macro is that you have an
additional piece of glass between the subject and the film  which can
degrade the image if it is not clean and a high quality optical glass.
