Hello, Looking to purchase good used Circular polarizsers in 46mm and 52 mm sizes. Looking for Nikon, Leica Heliopan or B&W. only. please respond with prices. USA only. Thanks Dennis. PS. Will buy outright, or will consider some kind of trade for a Canon G3 camera with 2 batteries. Approx 5000 clicks. Takes clean crisp photos and is in excellent condt. Just purchased the 46mm polarizer from Testuo so only need the 52 mm now. Anyone have on for sale.??
