When the wide-angle conversion lens is mounted, the angle of view increases from 24mm to about 16mm (35mm film equivalent). (The lens can be used on land as well as underwater.)
*The lens can be used on land, but slight vignetting (dimming) may occur in the four corners of the image. Slightly zoom in to telephoto to eliminate vignetting.
*A shadow may appear in the image if the built-in flash is used when the wide-angle conversion lens is mounted. It is highly recommended that you use an external strobe.
