.3X Ultra Fisheye Adapter - 37mm Threaded Mount (DS-FEWA-37)
1. Remove rear lens cap and thread the lens onto the camera.
If necessary use one step-up adapter ring supplied (27, 30 or 30.5mm).
The front lens cap can now simply be removed.
2. To align the sunshade to the camera, peel off the rubber sunshade and reattach it to the lens, having the widest part centered on the top. The sunshade must be centered (widest section on top and bottom) to avoid vignetting (dark or missing corners of the picture).
