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.
