Manufacturer description
The Rokkor 1000mm F/6.3 lens is of the catadioptric (mirror) type. This unique construction, consisting basically of several mirrors which bounce light back and forth between each other, permits 20X magnification within a relatively short overall length. Aperture settings of F/6.3, F/11, F/16 and F/22 are controlled by three built-in neutral density filters set into a revolving turret. A second revolving turret contains built-in Y58 (Yellow), O (Orange), R60 (Red) and UV filters which may be removed and replaced by other filters.
Typical characteristics of mirror (reflex) lenses
- Catadioptric system consisting of curved mirrors and optical glass;
- Much shorter, lighter and less expensive designs than conventional super telephoto lenses;
- Outstanding correction of chromatic aberrations;
- Since the aperture is fixed, neutral density filters are used to obtain a smaller aperture;
- Doughnut-shaped out-of-focus highlights.
