Tokina has announced the upcoming release of its new SZX Super Tele 400mm F8 Reflex MF, a mirror (or reflex) lens for select full-frame and APS-C camera systems.

The 400mm F8 lens manages to pack an impressive focal length into a relatively compact frame thanks to its catadioptric design. Usually reserved for telescopes, this design choice makes the smaller design possible, but at the cost of having the signature ‘donut’ bokeh, the lack of autofocus and having a fixed aperture.

The lens is constructed of six elements in five groups, offers a 1:2.5 magnification ratio and measures in at just 355g (11.82oz). It’s 74mm (2.91”) diameter and 77mm (3.03”) in length.

To make the lens as versatile as possible, the SZX Super Tele 400mm F8 Reflex MF has a 0.75mm pitch and 42mm thread mount that can be used with adapters to work with nearly any camera system. In addition to offering the base lens without an adapter, Tokina is also selling versions with included adapters for Canon EF, Nikon F, Sony E, Fujifilm X and Micro Four Thirds camera systems.

Below are a few sample photos taken with the lens, provided by Tokina:

Tokina says the lens is set to launch on August 7, but no pricing information has been given at this time. You can find out more about the lens and its design philosophy on Tokina’s product page.
