Hoya polarizer package colors
It was recommended that I use a linear polarizer for my Panasonic fz18..

I was looking at Hoyas and see they come in different color packages. Is there a color coding? Is a blue package better than a green?.

Also, I'm having trouble finding linear polarizers that are multi-coated. Is it ok to use a single coated?..

You could use a circular polariser, but it might be more expensive...

Hoya doesnt make a multi-coated linear polarizer. The HMC is the least expensive multi-coated filter..

Heres a packaging color chart. Green packaged filters are made in the Philippines. All others are made in Japan..

Standard - Purple9mm , Double coated (simple anti-reflective coating on each side) , Double.

HMC - Grey9mm , 3 Layers , Double.

Super HMC - Black5mm , 7 Layers , Single.

Sorry for reviving this thread, but I have a question about the standard Hoya Cir Pol filter (purple packaging). Many Ebay auctions from highly rated Hoya resellers show a chart in which the "Standard" grade Cir Pol filters are NOT coated at all. It appears this chart was taken directly from Hoya at one time, and it seems it is now inaccurate. The current crop of Standard Cir Pol filters is indeed mono-coated, even according to Hoya..

So, perhaps there are variants out there of the Standard grade Cir Pol (purple packaging) which are either uncoated (old stock) or mono-coated (newer version)..

Is there any way to tell which I have, having ordered from one of the more reputable Ebay retailers? Thanks.....

According to this page from Hoya, "Standard" filters have an anti-reflection coating on both sides..


Can you provide a link to where Hoya says otherwise?..

The above two auctions from Ebay indicate with the same chart that the Standard Cir Pol filter is uncoated. Both vendors got their charts directly from Hoya apparently. This conflicts with what Hoya now claims on their website. So, it would seem maybe that at one time, the Standard filters were uncoated, but now are monocoated..

Any tell-tale sign that mine is monocoated? Just look to see if there is little to no reflectance?..

Well, I trust information from ebay about as far as I can throw it. When in doubt, go with what the manufacturer says..

It is possible that the ebay listing is referencing the coatings added for light transmission. The standard filters have anti-reflective coatings, but no coating to increase the amount of light transmitted by the filter. In that respect, the standard filters can be considered uncoated...

Well, if a photo retailer outfit has over 20,000 ratings and a 99.99% favorable rating, I certainly wouldn't have any reason not to believe them when they say they got the chart directly from Hoya. Seems plausible when other seemingly reputable dealers have the same chart posted. Anyway, you're probably right about the conflicting information. Thanks.....
