An ideal lens for portraiture, the Nikon F-mount 85mm f/1.4 AF Lens from Rokinon is a short telephoto prime distinguished by its bright f/1.4 maximum aperture. This fast design, while benefitting its use in low light, also affords notable control over depth of field for selective focus applications. The optical design features one hybrid aspherical element, which helps to reduce spherical aberrations and distortion in order to realize high sharpness and clarity. Individual elements also feature an Ultra Multi-Coating, which suppresses flare and ghosting for greater contrast and color accuracy. Complementing the optical design is an Ultrasonic Dual Linear motor, which offers fast and quiet autofocus performance. Additionally, a rounded nine-blade diaphragm contributes to pleasing bokeh quality.

Funky Focusing
I know that the manual focus on this lens is focus by wire, but it doesn't seem to function as a normal lens on my Nikon D750. I don't know if I have a bad lens, or that's just the way it is designed. Setting the lens switch on manual and the camera focus selector on manual, nothing happens by turning the focus ring. You have to depress the shutter half way to manual focus. It seems as if depressing the shutter half way energizes the manual focus ring, and you can then focus manually. If you release the shutter button, and the standby timer for the viewfinder and meter expires, then depress it half way again, the preset focus is not maintained. The lens pops out of focus, and you must refocus with the focus ring. I don't know if this is the way the lens is designed to function, or if mine is defective. But if this operation is by design, then don't expect to use this lens on a tripod to take a whole sequence of photos using a preset manual focus. If the standby timer expires, every shot will be a meaningless blur. Maybe someone from B&H or the manufacturer can comment on this apparent anomaly. On the plus side, in limited use, auto focus appears quick and accurate, although it occasionally hunted, but maybe that's my technique rather than any limitation of the lens. Image quality and resolution are superior. Some have complained about vignetting, but I don't see it. Although I haven't tried to challenge the lens, distortion and chromatic aberration are likewise not apparent. Others have commented about the lens hood falling off. I would respectfully suggest that they are not mounting it properly. Line up the index marks, twist, and it clicks firmly into place. One other comment, the mounting flange seems tight. But for the crazy manual focus, I would give this lens four and a half stars for image quality, auto focus, speed, and overall value, but it gets only three for the funky focusing system.
Fair Autofocus, but does not hit the spot at 1.4
This Lens is not at all sharp at 1.4. It seems like the technology in it is very old. Just doesn't cut it for me.
