I bought a Samyang 14/2.8 last year when I was shooting an a99. Kind of bought on a whim as I generally don't shoot UW, but it was inexpensive so I grabbed one. I tried selling it recently but had no takers, so I decided to keep it and mount it on my a7r. I'd like to find a filter holder for this thing. I see that Samyang announced an SFH-14 holder a while ago, and some filters by Cokin, but I can't find it for sale here in the US. Anyone have this? If so, is it decent, and where did you buy it? Are there other options?
