DESCRIPTION

The Sima SLS-20 2x Telephoto Conversion Lens is an accessory lens to supplement a camcorder or a digital camera. As the name implies, it changes the magnification of the primary lens by two times. Put it another way, it narrows the vision by 200%, which allows the primary lens to zoom closer to the subject. For example, if the primary lens' focal length is 200mm, this accessory lens converts the field-of-view to the field-of-view of a 400mm lens.
