I just bought the 28-85 and 35-135 zooms, both of which have an 82mm filter size. I expect if I try to use my Cokin P filters, I'll get vignetting at the wide settings. Has anyone tried using P filters with these lenses?
No, sorry John, I have only tried holding the filters over the 28-85 otherwise I think with the Cokin attachment they will become very large. I agree that the attachment may well vignette.
