Optical Performance 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 Compared to other telephoto lenses the 900mm weighs in at 725g. With the lightweight and affordable price it's the perfect lens for the creative on the go looking to add a telephoto to their kit. Macro Option The field of view is 1.8° and the minimum focusing distance is 2.61 meters. These properties help the photographer avoid shadows while shooting close up images, and open up creative macro possibilities. Specific Bokeh Optical construction of the lens creates donut shaped bokeh for a one of a kind look. Focus Precise focusing could not be easier. The Tokina SZ 900mmPRO Reflex F11 MF CF X is equipped with wide and excellent grip focus ring that provides a smooth rotation range of 270°. Thanks to high quality processed metal parts and assembling processes, the focus ring rotates smoothly, even in low temperature environments, preventing dust from being sucked inside the lens. Super Compression Thanks to its long focal length Tokina SZ 900mmPRO Reflex f/11 can create images with a super compression effect, when the background looks close and enlarged compared to the main object. This effect adds to the image enchanting atmosphere.
