The optical design has 10 glass elements in 7 groups including 1 SD (Low Dispersion) lens that offers excellent resolution, sharp edge-to-edge results, and well controlled chromatic aberrations. Tokina’s exclusive Super Low Reflection Multi-coating provides natural colour and excellent contrast along with superior water, oil, and dust repellant properties.
The new ST-M auto-focus motor is quiet, fast, and accurate in still and video modes and thanks to an all-metal focus unit and high-quality lubricants; manual focus is tactile, smooth and precise. The lens is internal focus to maintain its compact size.
The Tokina atx-m 85mm F1.8 FE is fully compatible with Fast Hybrid AF system and all AF function settings. Fine manual focus adjustment along with Face/Eye Priority AF, Real-time Eye AF are also compatible.
Accurate focusing is supported by compatibility to MF Assist function, when fine focusing adjustment is operated by manual rotation of the focusing ring with the simultaneous interlocking with image enlarging function and bar distance display on the monitor.
Due to the data transmittance ability via electric contacts the camera obtains necessary data from the lens chip to correct shading, distortion and lateral chromatic aberrations. Optical corrections can be done by the camera as well.
By transmitting focal length data the Tokina atx-m 85mm F1.8 FE is able to get maximum use of In-Body 5-Axis Image Stabilization function of the camera.
