That's Great Steve - even with such a deep CP the vignetting at 10mm is negligible. Thanks so much for your help, it's really informed my decisions (and probably saved me money!!)

No problem Matt. As I say, It is so much better with just the one slot.

As an aside, I have also bought a series of step up rings to fit the 77mm wide angle adapter for my 10-20 so I can use the Lee holder and all of the associated filters with all of my lenses.

Yep, I've now got that option too - but that's for another day!

Silversnapper, any problems with vignetting with the step up rings? I've got a 67-77mm ring, but haven't yet stacked anything onto it - I know they push everything out a little bit, but is it significant enough to worry about?

Hi James,

Here's one that I have taken today with the CP.

Set up -
Nikon D90
50mm f1.8 ( 52mm thread)
52-67 step
67-77 step
77mm swa adapter to Lee foundation holder with one slot for a slide in and the front ring.
Hitech 105mm Cirular Polariser



This is straight out of camera and, as you can see, there is absolutely no vignetting at all.

Its good to know I can compare like with like Silversnapper - I've got the same camera and lens setup as you by the sounds of it!
