ProOptic 0.42x Semi-Fish-eye Auxillary Lens, Fits 37mm Filter Threads

Pro-optic 3-Element 0.43x Wide Angle Converter is suitable for consumer cameras that have lenses with a front 37mm filter thread. The wider effect lets you capture more into your shot without having to move back. Not recommended when livezooms are necessary. For mini-DV cameras that do not have a macro focus control, the lens will typically retain focus from the widest angle to approximately 1/4 of the zoom range.
