Mamiya RB67 & Cokin/other filters

Greetings all,
I am looking for some graduated neutral density filters. Everything I have
read is that the screw-on type are
less desireable for the graduated filters because you don't have the control
over where the graduated portion is situated in your composition.

The question I was wondering is whether the Cokin P family of filters is
large enough with the 77mm filter requirement.
I thought I saw something that showed that the Cokin filters are 74mm
across. Not sure if that is correct.

Is Cokin the way to go, or is there a better value (price/benefit) offering
out there? Are 4x4 filters better? If so, who?

Thanks,
Tom

Yes they are large enough for many lenses ( except 50mm ). I have got
the Cokin P series for my RZ and can use it nicely with all lenses down
to 65mm. The 50mm lens gets a tiny amount of vignetting if you use the
Cokin adapter but if necessary, you could use it with that little
sacrifice as well. I cut off the second outer filter holder section of
the P adapter and this one I can also use with the 50mm lens.
All my P filters are 99mm x 83mm in dimension -
Hope that helps a bit

Note that I have ever used them but they now do a range, X I think, that are
larger than P.

I used hitech filters in a cokin p holder on my RB67 for a little
while, I only have a 90mm and a 180mm so it was OK. No decent hoods
exist for the cokin P and I had flare problems with the hitech filters
so I ditched the lot on ebay and went for Lee.

Lee is a better alternative for the since the filters are larger and
you get a decent hood, the hood has 2 filter slots so you just need
that, the adapter ring and the filters. Still it set me back a fair
bit. There are possibly better alternatives to hitech in the US but
avoid cokin filters like the plauge.
