So I took a leap into more serious digital waters the other day. I have lots of Canon film bodies and lenses (don't we all) but in digital I was a PowerShot mid guy (owned 4) also Nikon CoolPix mid. So this 70D for me is a huge jump and so far very pleased. Now my question is filters and the quality/cost ratio as I'm not yet a "L" glass owner. I'm looking at B+W (I always want to say B&W as I'm huge audiophile) but of course they're pricier then the Hoya, Tiffen equivalent. I understand it's about "the glass" but what is the sweet spot for value as I don't have wads of cash to splash around. I'm considering this for my 18-135mm starter lens above a: Polarizer/UV & ND Vario or ND 1.8 to start. Take it easy on me as my desire for art transcends my current knowledge ! Thanks in advance for your input....
