Used Century Precision Optics DS-55WA-37 0.55x Wide Angle Adapter (37mm)

Here's a low-cost, high quality wide-angle solution. The .55x WAA offers a single-element design of negligible size and weight. This new adapter nearly doubles the angle of view and it allows close focusing - right up to the lens front - on many camcorders. Although technically a fixed wide angle adapter, the ability of many cameras to autofocus in macro mode allows this adapter to partially zoom at the wide angle end of the lens.
