i'm currently using adaptor rings to use my 67mm filters to even a lense as small as 48mm...the question left off my previous post is: is there any drawbacks and shotcomings in this practice? (like flaring and lower image quality?) i know many of you would suggest using rectangular Cokin filter sets, but i find that system highly impractical for my kind of photography, and i do not think many of us could afford dedicated glass filters for any lense filter size. so what do you think? kostas =============================================== so... no matter what, CHEER UP MY FRIENDS!
