The Kenko SGW-043 wide-angle lens is extremely small, and was created
for high resolution compact video cameras that have 37mm sized filter
threads or smaller. This high-quality lens has an extreme curvature of
field, or fish-eye effect - a creative look for extreme sports,
web-casts, etc. The optical glass lens elements are multi-coated to
reduce the possibility of flare, ghosting and internal reflection.
