Can't get the lens mount adapter off my lens :(
 

I just bought the Cinevate Mount adapter to use it on my nikor 85mm f1.4 lens and I used it on the 7D without a problem
But now when I want to use the adapter on another lens, I can't get it off the lens. :(
Is there some sore of trick to remove it ?

If it's like the KAWA adapters that I have, there is a little spring loaded tab on the adapter, pull up on that, it will take the pin out of the slot in the Nikon lens, then rotate the adapter off. That fooled me too, and there is no documentation about it, I'm sure many adapter users have had a few moments of consternation over this.

GREAT !!!!
Thanks Keith. You just made my day. Just by pulling the little spring it was really easy.
I was just about to order several adapters.
One for each lens. hehe :D
