I just bought a used fish eye and i got it for a steal. I got a Mark 2 bayonet. but it wont go on my camera! I was wondering if there is two models of this lens one for the gl2 only and one for the vx i looked around and havent found anything. I did asume that there all the same because i no the screw ons are all 58mm. Unless iam an idiot and just cant get it on or i made a mistake. Maybe i have defective gl2 i dont no and i need help to figure this out.

If you got the lens without the little instruction sheet on "how to to put the Fisheye on the camera" then the instructions are here too:
