So I accidentally dropped my 5D Mark II on my hardwood floor. Luckily there's no damage to the camera or the lens but my b+w polarize filter is stuck on the lens. I notice a small dent on the side of filter preventing it being screwed off. Is there anyway to get it off or do I need to get a professional to take it off for me? Will one of these lens filter wrenches remove it? http://www.the-digital-picture.com/Reviews/Lens-Filter-Wrench-Review.aspx
