No.
Non-polarized light that enters a Linear Polarizer
remains fully polarized as it exits. That is why a
linear polarizer is sometimes troublesome to the
camera components that rely on beam splitters.
If light exiting a linear polarizer WERE ordinary
nonpolarized light, then this whole issue of what
cameras have The Problem would not exist. If the
light exiting EITHER a CPL or an LPL were alike in
the sense of BOTH being non-polarized, then why
would it matter which to use for which camera ?
I am soooooo amazed at the incredible bumbling
and bungling around a very simple issue. I even
heard [elsewhere] from a verrry insistent "Online
Expert" who INSISTED that "circular" is ALWAYS
better becuz that means it's round and it rotates,
so it can be adjusted to maximum effect ! IOW,
to him, circular is the opposite of rectangular.
