Query: Beware of Glare and Flare

I trust Hoya brand, but even though this filter says it is multi-coated, one of those coats is not anti-glare. Make sure you have a circular polarizer handy. Otherwise, you may run into glare and flare spots with your photos.I live in Seattle, so it is difficult to tell when cloudy days receive the gift of sunlight here and there. After a strenuous uphill hike to the top of a spectacular view, being without a polarizer, several amazing pictures had glare and flare spots due to the sun peaking out. Total bummer.In summary, I don't have much experience with filters (yet), so maybe this is commonly known with UV filters that are not labeled as pro, or it is a known fact in general. I gave this product 4 stars due to the ambiguity of the multi-coated claim; it is definitely not anti-glare. Take it for literal value (UV coated only).On the bright side (no pun intended), the lens cap for my Canon EOS 500D (Rebel T1i) fits nicely.
