Controlling Defocus Image – Making Image Blur
Lens AF DC-Nikkor 105mm f/2 D
While pushing the DC ring lock release button, rotate the DC ring toward the R (rear) side to blur the background, or toward the F (front) side to blur the foreground. To effectively blur background or foreground images, turn the DC ring so the f-number on the DC ring (aligned to the DC ring index) is same as the aperture in use. Turning the ring beyond the aperture in use lets you create a soft-focus effect.
- Defocus control should always be performed before focusing. If you rotate the DC ring after focusing , or during focus lock in autofocus photography, your subject will be out of focus.
- With the DC ring at either the F or R side , the distance scale may not show the correct distance.
- The effect of defocus image control depends on subject conditions , such as subject-to-background distance, subject-to-foreground distance, etc.
- Image blur cannot be verified through the viewfinder. To obtain the desired effect, take a series of shots with the DC ring at various settings.
