The Cokin R730 58mm 0.5x Wide-Angle Conversion Lens is a quality conversion lens designed to broaden the field of view when attached to a digital camera's or camcorders existing lens.

      Comments about Cokin R730 58mm 0.5x Wide-Angle Converter Lens:

      The converter is well built, however, image quality suffers!! I didn't expect it to do wonders but it is just a waste of money.
      When mounted on my canon lens all photos were soft with very high fringing I would not recommend this item.
