Optical Performance Long 400mm focal length of Tokina SZX SUPER TELE 400mm F8 Reflex MF while being such a compact and lightweight is realized thanks to catadioptric optical design. Mirror lenses are tele photo lenses that incorporate a combination of 3 lenses silvered on the outside of the glass to reflect light back and forth between the ends of the lens. This structure folds the light cutting the tube length in half. In this way the construction makes the physical size of the lens around a third of the size of a conventional lens and allows a lightweight body, because the mirrors are much lighter than the optical glass. Lens elements inside the lens are coated with multi-layer anti-reflection coating for effective light intake and as a result, for increasing shutter speed in low light conditions.Mirrored surfaces of the lens elements incorporate high-reflectivity silvered coating and a protective antioxidant layer on the back side for a longer product lifetime. Compact and Lightweight The Tokina SZX SUPER TELE 400mm F8 Reflex MF is suitable for travel photography since the lens is compact and lightweight, and yet will help you to capture far objects that cannot be reached by standard zoom lenses.  Weighing just 340g (without mount adapter) this lens can be easily packed and carried inside a pocket or small bag, suitable for travel photographers seek ing lightweight gear.ds Macro Option The field of view is 6°8' (by frame diagonal) and the minimum focusing distance is 1.15 meters. It gives magnification 1:2.5 to capture an object with size 6x9cm on full frame.
