I have the 58mm version that I use on my 5omm f/1.4 and 85mm f/1.8. Using the LCW FaderND does mess with my autofocus, so I'm forced to use manual focus--but when I have a subject that can stand still, I love the effect.

ND filters are rated in stops, so if you want to go from f/8 down to f/2, thats 4 stops (same as f/11 to f/2.8). From f/8 to f/2.8 is 3 stops, etc. Sometimes the stops are translated to a log value, so a 3 stop filter is called 0.9, 6-stop is 1.8, etc., and sometimes they're labeled as a filter factor, so a 3-stop filter, which lets in 8-fold less light, is called ND8.
Yes, there are variable ND filters - check out the Fader ND (B&H sells them) or the more expensive Singh-Ray Vari-ND filters. You can also make your own - if you have a CPL you can stack that on a linear polarizer to make a variable ND filter (in fact, that's essentially what the two products I mentioned are).
Hope that helps...

Hi,
Also consider just a simple 3-stop ND filter, as they are relatively inexpensive. I used to use Tiffen but I found that they were affecting color way too much. I've been pretty happy with the Marumi ND 8 DHG. It's not as solidly built as the B+Ws I usually use, but it's good optically and good value for money for the price (<$40 for the 77mm one).
Sean,
Beautiful shot as always!

Thanks all!!
Since all my lenses have different filter sizes, I decided to not spend a fortune and get a variable ND filter for just one lens.
I took Tony's advice and got the non variable filter lens for my 50mm f/1.8 II. Tiffen ND 0.9 Filter $15 from B&H.
Things get so much cheaper when they're for 52mm []
So far no color issues that PS can't fix. No AF issues. The viewfinder is darker and somewhat hard to see but nothing I can't get used to.
Here's my very first quicky test self-portrait that I did.
