2.Actualizes 7mm focal length and a diagonal angle of view of 180 degrees for APS-Csize.

3.Corrects aberrations using a complex aspherical lens. When fully opened, produces both high resolution and high contrast at the center of the lens and also around the periphery of the lens.

4.Petal type hood and multi-coatinghelp control flaring and ghosting.

5.Offers robust durability by incorporating a stiff aluminum base frame.

Your 7mm fish eye lens is designed with its own mount. Users can take photographs easily without installing an additional adaptor by mounting the lens directly onto the camera.

Please read these directions prior to using your lens.


Your VIV-7MM-Plens mount is uniquely designed for Pentax cameras.

Attaching Your Lens to Your Camera

Hold the hood locking area of the lens gently, and align the lens mounting reference point or line with the lens ring mount of the camera. Next, push the lens into the camera and turn the lens softly until it makes a clicking sound, and the depth of field scale is positioned on the upper part of the camera.

Detaching Your Lens from Your Camera

Hold the hood locking area of the lens gently, and press the lens release button on the camera. Turn the lens in the opposite direction as when attaching, and carefully pull it out.
