Focus Adjustment - Vivitar 13MM-N Instruction Manual

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 1) 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
(1 to ∞) and focus on the clearest subject by using the indication signal on the camera or
by checking visually.
