Anyone who's interested in buying a raymod fisheye give me a shout. 58mm thread but if you need it for a VX1 you can get a step down ring for about £2 on ebay. It's roughly as wide as an MK1, wider than an MK2 & Opteka fisheye (did a direct comparison for both). If you would like an pictures of the lens itself let me know. Comes with 2 lens caps and a pouch.
I am looking for about £50/40 but I am open to prices.
Located near London. Let me know if you're interested.
