Page 3: Introduction
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. -

4. Filters Normal (IA Skylight): This filter should be used whenever no other filter is necessary. ND 2X and ND 4X (Neutral Density): These filters control the light passage since no diaphragm system is provided in the reflex lens. Exposure factor is 4 times with a ND4X, i.e., the light in-take through the lens is decreased similarly as it, stopping-down a normal lens with an aperture, by 2 stops. -

6.

8. Cleaning and maintenance The lens should always be capped when not in use. Like other precision optics, it should never be simply wiped with a tissue since this may abrade the surface with any dust clinging to it or on the lens. -
