The Lens was actually a Sigma 10-22mm shot at 10mm.

^The graduated kind

You have a bit more gear than the average person "getting in to it". But, I understand. I would recommend this ND filter. I use mine on my 70-200 f/2.8 and my 24-70 f/2.8. It takes some awesome daytime long exposure shots. And, its B+W, so you know its good.

You should really invest in a B+W 10 stop ND filter.

The nikon 77mm CPL goes for $149 on amazon and is really good.

Take a look at the B+W ND filter. I don't have it, but it is highly rated and B+W has a good name.

Here is the B+W graduated ND filter. Also good.
