I don't suppose a Z-pro filter will fit into a P series adaptor ring will it?

The Z-Pro ones are 100x100 (or 100x150 for the grads), which I think is the sane size as the Lee Filters. The P Series is 83mm wide so no go :(

oh ok thanks :thumb:

is there much difference between the Z and P range?

P range is OK, but I do get a bit of vignetting at the wider end esp with the EF-S 10-22, but anything in front of that will show up.

Z-Pro looks better built, but I've not actually seen it in the flesh, might be worth comparing with the Lee kits as they are the dogs proverbials :thumb:

Lee - very good, and well made stuff.... but far from cheap - especially the grads!
