They add new anti reflective baffles to increase the efficiency
of the baffling. They also add both an ultraviolet and an
infrared filter, to trim what the meter cell sees down to the
visible spectrum. Then they add a coloured filter that brings
the meter response to that of film.
After that, the meter is calibrated for accuracy and linearity
to within 1/6 of a stop.
A Zone VI modified meter sees light the same way that film does.
A Zone VI modified meter is colour blind, which means that it
will not be thrown off by strongly coloured subjects.
It is the only truly accurate spot meter.

Where can you have this modification done to the Pentax
Spotmeter V and what is the cost for the work.
thanks
