Page 3: Mounting Your Lens
Your new catadioptric lens or Reflex Mirror lens is a highly developed computer designed product, using the merits of both reflex optics and refraction optics. This gives you very sharp picture quality with less color aberration, which is considered the most harmful factor in the field of telephoto photography. Each lens comes with interchangeable rear insert filters. -
Page 4: Depth Of Field
4. Depth of field The area in acceptable sharpness in front of, and behind, the subjest in focus is called tole Depth of Field. The aperture selected and e distance of the subject, as well as, the focal length of a lens determines such depth of field. Because of the longer focal length of your Reflex lens the depth of field is acutely narrow, for example, with a 500mm f8.0 lens, at a distance of 6 feet, the depth of field is only 1/2 inch wide.
