er, it can be owned for only $200+ ...=P (77mm somemore)
anyway ya do consider buying 77mm-s unless you are very very sure u will never use 77mm lens forever, or at least a long time. Its economical to get 77mm CPL and get step down rings for your smaller lens so you only need 1 cpl for all....but some ppl find it trouble some to use step down rings, i did at least..haha..
