ND Filters

[Roughcollie]

I have a Pentax 645n which i use for landscapes,I am looking to buy a couple of ND Filters for it,I have the Lee Filter holder which I use for my Graduated Filters,but am not sure whether to buy screw in type or Lee ones?
Any advice on this please.

It depends. I always use screw-on filters if the lens allows for it - but I only have 1 or 2 non-UV filters per lens. Filter holders make changing filters easier, but carry the holders around means more weight.
