Following last year’s release of the AF 85mm f/1.4 FE for the Sony E Mount, Samyang/Rokinon today unveiled a version of the lens for Canon’s full-frame mirrorless RF Mount. According to Rokinon, the new AF 85mm f/1.4 RF is “arguably the best value, high performance and affordable autofocusing portrait prime available.”
Optically, the Samyang/Rokinon AF 85mm f/1.4 RF looks to be identical to the Sony FE version. There are 11 elements in 8 groups, including 1 Extra Low Dispersion (ED) element and 4 High Refractive Index (HRI) elements to cut down on chromatic aberration and allow for a smaller lens design, respectively, as well as the company’s Ultra Multi Coating (UMC) to eliminate ghosting and flare.
The lens boasts a 9-blade circular aperture, and the only ‘decoration’ on the lens barrel is the AF/MF mode switch. For autofocus, the lens uses a Dual Linear Sonic Motor (DLSM), which you can see demonstrated in the video below created for the Sony FE lens launch:
