P3D Polarizers

[Bob_Maxey@xxxxxxxxxxxx]

>>3. How might light transmission of a Vivitar filter compare to, say, a
set
of plastic filters, as typically available from Reel 3D or Dalia?  Might a
Vivitar polarizer be "more efficient," meaning more light transmitted??


There can't be too much difference because all glass polarizers are made
from polarized material sandwiched between glass. There are really not that
many differences in materials from manufacturer to manufacturer because
polarizers have to meet certain specifications. Photography is only a small
percentage of the total user s of Polarizers.

Granted, there are many different types of polarized plastics made, but
chances are, only a small range of materials are regularly used by
manufacturers of sandwiched glass polarizer filters.
