Description
●Compact fisheye lens to shoot through eyes of small marine life, so-called "insect-eye lens" imaging. The lens is designed to use at approx. 80mm zoom position (35mm film equivalent) not as like standard wide conversion lens.(*4)
●Underwater view angle is 150°. The subject side lens is compact diameter 32.9mm and minimum focal length is 0cm to capture a tiny subject in entire image together with background.
●The UFL-M150 ZM80 is an afocal system conversion lens which does not affect brightness of combined master lens and enables you to use benefit of camera's AF (auto focus).
●You can take full advantage of INON "S-TTL" Auto exposure of INON Z-330, D-200, S-2000 to benefit appropriate exposure images simply by pressing shutter release button.
●The lens barrel has threaded wall to adjust lens position back and forth to accommodate with different master lenses among many compact digital cameras (*5).
●The UFL-M150 ZM80 is attached on compatible camera housing via combination of "Mount Base" which is exclusively designed for each housing and appropriate "Mount Converter".
(*1) Optional "M27-M67 Mount Converter for UFL-M150 ZM80" is necessary.
(*2) Optional "M27-AD Mount Converter for UFL-M150 ZM80" is necessary.
(*3) Optional "M27-LD Mount Converter for UFL-M150 ZM80"is necessary.
(*4) This lens is designed for underwater use only. Using on land will not form an image.
(*5) Not usable for a compact digital camera carrying large master lens or super zoom function, or an interchangeable lens for a SLR camera system.
