3. Mounting and demounting of camera
Mounting Hold the hood locking area of the lens gently, align the lens mounting reference
point or line with the lens ring mount of the camera, 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.
Demounting Hold the hood locking area of the lens gently, press the lens release button on
the camera, turn the lens in the opposite direction as attaching and pull it out.
4. Focus adjustment
The user can set the focus of a subject by turning the focus adjustment ring when using this
Fish-Eye Lens, as it is an MF (Manual Focus) adjustment lens.
1. When focusing on a subject from a long distance, turn the focus ring to the left 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 and
focus on the clearest subject by using the indication signal on the camera or by checking
visually.
This Lens is a single lens, zooming is therefore not possible.

5. Brightness control
The user can set the brightness by turning the aperture adjustment ring.
6. Camera settings
Some cameras require special settings when using this lens. Please refer to the following and
set the camera when necessary. The Pentax/Samsung cameras can also be operated in AV
mode.
① Set the camera mode dial to „M“.
② Set the focus adjustment lever of the camera to „MF“.
③ Some digital cameras are able to set the focal length and the brightness when attaching
an MF lens. The MF lens can be used more efficiently if the focal length and the brightness
are set on some digital cameras.
*The shutter speed of some cameras changes automatically, if the focal length and the
brightness are set. The desired brightness is set by turning the aperture adjustment ring.
The following instruction is just for Pentax ( amsung) cameras.
1. AV Mode
The 8mm F3.5 Fish-Eye Pentax/Samsung supports Av mode.
1) Align the A mode indicator to the depth of field scale by pressing the A button
installed on the aperture adjustment ring of the lens.
2) Set the mode dial of the camera to „Av“.
