Digital Polarizing Filters

[FiveD]

Question:
Is anyone on board who can validate there is truly a difference between a polarizing filter listed as "digital", opposed to one that is not listed as "digital"?

I am now in the market for a high end circular polarizing filter to mount on my 70-200 2.8L IS and 35mm 1.4L lens. Many to choose from and a broad range of prices. Is the term "digital" just a marketing term, or is there any real value? Price is not the object here, quality is.

Thank you

Usually "Digital" is being employed to indicate that both sides of a filter or lens are coated to minimize reflection. Good multi-coated glass should be coated on both surfaces anyhow, so the absence of the term doesn't necessarily indicate inferiority; rather it reflects something that's possibly older than the "Digital" counterpart.

The term "digital" is purely a marketing gimmick in this case, as it is so often in many advertisements for so many products. It's impossible for a glass filter to be digital in nature. Calling digital is just a stupid way of describing a decent quality multicoated filter.

Here's the filter I chose for all my L zooms with 77mm filter threads: http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=155155&is=REG&addedTroughType=search

Skip, I like Hoya, also. However, I would go for the Super-HMC. In the CP, it is the Pro1....not the Digital Pro1. The Digital and the non-Digital have the same coating, except the non-Digital has an add'l protective coating.

In USA, the best place I found is http://www.2filter.com/prices/specials.html You need to put them in your cart to see the reduced prices for the Hoya's. The same one you referenced at B&H is $145 here and the Pro1 77mm is $168....no shipping over $66.

Thank you for the feedback.

I have just purchased the B+W 77mm Wide Angle Circular Polarizer Multi Coated Thin Glass Filter.

I will be using this for my landscape photography when the right situation is calling for polarizing enhancment. The lens for mounting is the EF 35mm f/1.4L USM, and 17-40 f/4L USM. I will be using the 72 to 77mm step up ring for the 35mm.
