"Bug Eye Wide Angle" INON
*This product is designed for underwater use only. Not usable 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. *We are very well conscious of marine environment and marine lives not to stress and harm them when shooting with this product.
*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.
*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)
The lens is called ULF-M150 ZM80 Micro Fisheye Lens and it is tiny super wide angle lens that reminds me of some endoscope lenses used for special purposes. The UFL-M150 ZM80 is quite alternative from normal underwater wide angle designs and is the only lens of this type commercially available that I know. The idea of the lens is to get extremely close and extremely
wide for a special kind of macro photo.
I first tried the lens on land but very soon I realised that it is impossible to focus with it topside. Quick glance to the user manual verified the fact that this tiny lens only focuses underwater. The lens is mounted to an adapter ring so that the rear lens element sits about half a cm from the housing port glass. (I tried also with the lens touching the port glass but could not get the lens to focus underwater.) According the user manual, which I actually had to read through this time around, the right distance of the lens is between 0mm and 10mm depending of the camera’s lens and the port of the housing. Once underwater the lens works by using your camera zoom to get rid of the vignetting (With S95 this was near the max) and then finding the right distance where the picture start to get in to focus. After this you can use your cameras auto-focus to get the fine focus finally locked. Even with the full zoom on S95 the M150 ZM80 lens is extremely wide and by pulling the zoom back a little you get the full 150 degrees.
