Introduction
Thank you for purchasing the VIV-7MM fish eye lens. This lens will provide you with many
unique and exciting photo taking opportunities which we hope you will enjoy.
Features of Your Lens:
1. Conforms to APS-C (1:1.5x) size digital imaging format.
2. Actualizes 7mm focal length and a diagonal angle of view of 180 degrees for APS-C size.
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-coating help 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.
