Hi Please excuse my ignorance especially where terminology is concerned but I am a beginner to this milarky. I love doing landscape and am looking at getting ND filters. With the long term in mind am I better getting the rectangular or circular? My canon 17-85mm lens takes a 67mm UV filter but I cannot find any ND circular filters this size. I understand it is possible to get an adapter ring but don't know what size I should be looking for. Can someone please point me in the right direction in the most basic of manner
Thanx in anticipation
