Hi,

I'm thinking of buying a circular polarizer via eBay, and it seems that
different sellers are extolling the superiority of each of the above Hoya
filters above the other. So, does anyone know what the difference between
those that come in the green and blue cases? A quick google comes up with
nothing useful!

Thanks in advance,

Kieran

Starting with the LEAST fancy...(taken from web site)

Green filter box = UNCOATED
Blue/purple filter box = 'monocoated' a.k.a. 'double coated'
HMC = multicoated
HMC ultrathin = multicoated, thin to avoid vignetting with wide angle
lenses
Super HMC = 6 coatings, 99.7% light transmission
Super HMC Pro 1 = special 1mm glass, 6 coatings, 99.7% light
transmission
Pro 1 Digital UV = (can't tell what's special about this, but it costs
more!)

Thanks for the reply! Can you point me to where you got this information?

I think this is amusing. While the seller below seems to have 'got it right'
in terms of blue label being superior to green, the explanation is not
altogether clear:

And this one, where the sellers claims green label is better than blue:

Once more, thanks for the information.

I got the information from

And taken from

http://www.firstcall-photographic.co.uk/scp/Camera_Accessories/Hoya_Filters.html

"As specialists, we stock four different types of Hoya filters. The
"standard" Hoya filter range comes in the blue box and is multi-coated.
The budget range comes in a green box and cheaper because it is only
single coated. The HMC range has even better multi-coating and,
optically, is the rival to the hand-made German filters from B+W or
Heliopan. At the top of the range is the SHMC Pro-1 range. This Super
Hoya Multi Coated filter is a mere 1mm thick and perfect for wide-angle
lenses to avoid vignetting."
