Hey All... I just got a new Tamron and it's filter thread is 67 mm (which means I need some new filters). I got a POS polarizer for my kit lens and really regretted it so I want to make sure I get a decent one for the new Tamron. Does anyone have recommendations for brands / types of filters? I was tossing around the idea of a warming filter but I'm not sure it's really necessary as I can easily warm the pics during the RAW conversion. I was also leaning towards the typical Hoya multi-coated filter. Any advice?
