Inon UFL-M150 ZM80 Underwater micro fisheye Lens

Compact fisheye lens to shoot through eyes of small marine life, so-called "insect-eye lens" imaging.

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 lens 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.

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).

The lens barrel has threaded wall to adjust lens position back and forth to accommodate with different master lenses among many compact digital cameras.

The UFL-M150 ZM80 is attached on compatible camera housings via an M67 mount adapter #4562121436237
