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.

Your VIV-7MM-P lens 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.

please follow the steps below:

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.
