    Can't seem to find anywhere that tells me the tread size of this lens. Anyone know? I'm looking at getting a ND Grad filter. Never used one before though, so if anyone can give me some tips on how to use one/best one to get I'd appreciate it :smile:

    It should be 77 threads like the most of them are. I don't use ND filters so I don't know much about them. I have 2 120 backs on my RB67 so I use one 'fast' film and one 'slow' film.

    I have 127mm f/3.5 K/L lens on RB67 ProSD and the thread size is 77mm.

    I believe that the Cokin P-series filters will work with lenses up to at least 77mm and the advantage of the ND grad filter is that you can slide the filter up and down to match the horizon.
