FS: Singh-Ray 77mm Vari-ND filter

This neutral density filter adjusts from 2 2/3 stops down to 8 stops. Due to it's ability to adjust, it is big. Therefor it tends to cause slight vignetting on anything under 30mm equivalent. Also to be understood, due to the way it adjusts you need to shoot either wide open (2 2/3 stops ND) or totally stopped down (8 stops ND) when shooting wider than 50mm for smooth effect. Once you go passed 50mm you can use any amount between open and closed cleanly. I am moving onto 100mm filters so this has got to go.

Used but looks brand new. Clean optics, dust free, scratch free, smooth adjustment. Case has some wear on the logo from being in my bag but other than that everything looks new.

Retails for $340 so maybe $275 shipped?

I also have a Tiffen 77mm Digital HT Clear/ND .6 graduated filter. $50 alone or $40 with the above.
