I'm swapping out my filters for the new Haida NanoPro series, so I have a set of 150mm Neutral Density filters, complete with holder and adapter rings for sale. These filters have been used very sparingly, no scratches or other kind of blemish; they're still like new. Made by Haida from Schott glass, they'rere highly respected for their build quality and color-neutrality. They're often praised for having zero color cast; this doesn't matter if you shoot B&W, but it's good to know if you ever use color. The 150mm universal filter holder will also accept LEE 150mm filters. It's a solid holder, made of high-quality aluminum, as are the adapter rings. The holder can accept up to 3 filters at a time. Here's what's in the kit: 150mm Universal Filter Holder 77mm, 82mm, 95mm adapter rings - 95mm not pictured 150mm ND1.8 filter (6 stops) - not pictured 150mm ND3.0 filter (10 stops) 150mm ND4.5 filter (15 stops) 150mm x 170mm Hard Graduated ND1.2 filter (4 stops) soft case that holds all of the above - not pictured This cost about $850.00 new, I'm asking $600.00 USD I'll include shipping to Canada and the USA in the price, and PayPal fees are also included. Let me know if you have any questions; thanks.
