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 a spherical 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.

Your VIV-7MM-S lens mount is uniquely designed for Canon 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.

Focus Adjustment
You can adjust the focus of the subject you are photographing by turning the focus
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 right
(∞ 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 left
(0.3 to ∞) and focus on the clearest subject by using the indication signal on the camera or
by checking visually.

Brightness Control
You can set the amount of brightness you want by turning the aperture adjustment ring when
using your lens.
When you turn the aperture adjustment ring between 22, 16, 11, 8 and 5.6 you are making
1 stop each turn. There are 1.5 stops between 5.6 and 3.5. Brightness can be set more
precisely by making half stops as well (see below).
5.6 and 8 are 1 stop apart (1EV).
Set a 0.5 stop (0.5EV) between 5.6 and 8
-6-
Camera Settings
Some cameras require special settings when using this lens. Please read the information
below and set your camera accordingly.
The aperture of the 7mm fisheye lens is not specifically geared to your camera.
If the F stop is set above 8, you may not be able to set the correct focus due to difficulty in
viewing the subject through the camera’s viewfinder. Turn the aperture adjustment ring and
fully open it when attaching this lens to the camera, and then turn the aperture adjustment
ring again to set the depth of focus and brightness you want prior to shooting.
-7-
Camera Settings (continued)
1. Set the camera mode dial to ‘M’
2. Adjust the shutter speed to achieve
the appropriate brightness.
-8-
Camera Settings (continued)
The shutter speed of some Canon cameras changes automatically if the shooting mode dial
is set to Av and the brightness is set by turning the aperture adjustment ring. Therefore the
shutter speed is not required to be set additionally as when using the M mode.
(The camera settings discussed apply to the Canon 40D camera. Settings for the camera
or the menu may be changed depending on the model or due to a menu upgrade. Refer to
the camera manual or contact the camera manufacturer for more detailed information.)
