Focus ring on your camera should be set to infinity.
Focusing is achieved by adjusting:
A) the Macro-Focus or
B) the Auto Focus feature of your DV camera or
C) the back focus adjustment on the camera lens.
Be aware of your depth of field. At f16, everything is in focus, including any dust on the lens!
Use the N.D. filters to decrease depth of field.
If you use a MATTE BOX with FILTERS or BELLOWS, you can use the Red Eye ™ wide angle adapter with it.
You can use your existing lens hood. Simply screw the Red Eye ™ adapter on your lens and replace you lens hood.
Be aware that adding the Red Eye ™ on top of other screw on filters increases the possibility of vignetting.
The adapter works well in shots where a dramatic angle is needed to increase perspective or to accentuate the effects of fast motion, or on shots that float through a room on a steadicam, to smooth out movement.
