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.

lens softly until it makes a clicking sound, and the depth of field scale is positioned on the
upper part of the camera.

camera. Turn the lens in the opposite direction as when attaching, and carefully pull it out.

adjustment ring on your lens, as it is an MF (manual focus) adjustment lens. To do so,
please follow the steps below:
1. When focusing on a subject from a long distance, turn the focus ring to the left (∞ to 0.3)
and focus on the clearest subject by using the indication signal on the camera or by
checking visually.
2. When focusing on a subject from a short distance, turn the focus ring to the right
(0.3 to ∞) and focus on the clearest subject by using the indication signal on the camera or
by checking visually.
