hello, I am actually shooting landscape with two systems :
-hasselblad V with 180mm , 80mm, 50mm lenses and SWC
-ALPA with schneider kreuznach 24mmXL and 47mm XL apo digitar.
both with a Phase One P25+ back.
I would like to buy ND filters wich will fit the two systems.
One of my concern is the possibility to fit a system in front of the Schneider Kreuznach center filter for the 24mmXL.
I have heard about LEE, Cokin.
So my questions : wich is the best value filters system ? What would be your choice between the different stoppers ND6 ND1O ? and the graded nd filters ? hard ? soft .3 .6.9 ?
I am shooting mainly seascapes, but also mountains...If I could afford all of them ...but unfortunately it's not an option.
So any advices would be welcome.
