I have just ordered Cokin Z 77mm adapter and the ND Grads from Stu. Out of stock and will take about two weeks to get them in.
If only the rain would stop. I am trying to set myself up for a three month outback trip, through the centre to the top, turn west over to Broome via the GRR and down the WA coast and then back via the Nullabour. Would love a 400mm Canon but on pension money that is a wish to far. Still, have the 50mm prime, 70-200mm f/4, 12-24 UWA and a 100mm macro. just need the skills now. Cannot even do bug and flower shots in the garden with the rain.
