Caleb,
Yes they are and I received them couple of days ago.
And now I have all the lenses. Taking lens (Nikon 85mm f2), Kowa BH, and Redstan clamp.
But I'm having a really difficult time focusing. Or I've not succeeded at all in focusing.
First I focus with the Nikon, which is connected to the Redstan clamp. Then I put on the Kowa BH and I try to focus with that, but when I look at what I've shot on the D4's lcd screen, it's hardly in focus. Am I doing something wrong? I also received a ring with the clamp and I have no idea what this is for? Is this for the closeup ring?
But most importantly, I really don't understand why it's not focusing at all… :(
