A local guy is offering me his CPL bought in 2007 and only used the summer that year.
It's a B+W 77mm CPL Thin NOT multicoated.
now I asking, what is the THIN ? That is the first time I hear this,
is there any difference or advantage of having a 'thin' CPL versus the 'normal' sized CPL ?
And is it worth buying this one even if it is not multicoated?
I hear B+W is a very good brand, plus for the multicoating criteria, I never saw any difference in the UV filters,
is it different for CPLs?
