■UFL-M150 ZM80 Underwater Micro Fisheye Lens
●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.
[When using UFL-M150 ZM80]
*The UFL-M150 ZM80 is a special conversion lens to capture a small subject in entire image when shooting at very close range to obtain so-called "insect eye lens imaging". Its optical design makes lens diameter relatively small and provides minimum aberrations when shooting a subject just in front of the lens. So if you shoot whole underwater landscape with focusing to infinity as like using ordinary fish-eye lens, it may not produce intended result.
*This product is designed for underwater use only. Not usable on land. Use a tank or bathtub filled with water when conducting test shot on land.
*When shooting, zoom towards to telephoto side at approximately focal length 80mm (35mm film equivalent) until no vignetting is observed. Shooting at wide end setting will give you a circular fisheye image (view angle 150 degrees).
*Since the lens has small diameter and enables to focus at 0cm from the lens surface, depth of field gets enormously shallow when shooting in few mm distance. In such a case, it is recommended to use small aperture setting.
*This product is not compatible with any of INON "Lens Holder" due to product feature to adjust mount position back and forth by screwing it.
*The built-in flash light could be blocked depending on housing, shooting distance or angle of view etc.
*Be well conscious of marine environment and marine lives not to stress and harm them when shooting with this product.
