The iDiving WTC is a waterproof lens for land and underwater use, with the function of multiplying by 2 the focal length of the lens mounted on the camera, maintaining the possibility of focusing to infinity. It doesn't work with wide-angle lenses, but with tele-macro lenses, such as Nikon's 60 and 105mm or Canon's 60 and 100mm, as long as they have a narrow enough field of view that the WTC lens doesn't vignetting.
Precisely to minimize the possibility of vignetting, in addition to maximizing effectiveness, it is important that the iDiving WTC is mounted as close to the camera lens as possible.
The WTC-2 is designed for cameras with APS-C, DX, APS-H sensors and up to full frame size.
The iDiving WTC is mounted on the photographic equipment using the M67 thread, the most used for underwater lenses. In case of not having the exact thread in the photographic equipment, a thread adapter can be mounted, either folding, for pressure mounting, or to adapt one type of thread to another.
