Sea & Sea Wide Angle Conversion Lens for DX-1G & DX-2G Digital Cameras

Can be attached easily in one turning action utilizing the bayonet system; can be attached and detached underwater. (The lens can be used on land as well as underwater.)
When the wide-angle conversion lens is mounted, the angle of view increases from 24mm to about 16mm.
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.
