Portrait telephoto for Nikon F mount
The Rokinon 85MAFN is an 85mm f/1.4 manual-focus prime built for Nikon F-mount DSLRs. Its 28.3-degree angle of view and wide maximum aperture suit portrait work on full-frame and APS-C bodies. An integrated automatic chip lets the camera control aperture and record EXIF data without adapters. The lens weighs 1.40lbs and uses a 72mm filter thread.
Thermal noise and power profile
As a purely optical manual-focus lens, the 85MAFN has no motor, electronics cooling or power draw. It adds no audible noise and no heat to the camera system during normal shooting. Operation is entirely mechanical aside from the aperture chip, which draws negligible power from the body.
Bundled accessories and their effect
The box includes a front and rear lens cap plus a protective lens case. The caps shield the 9-element, 7-group optical formula and multi-layer coating from dust and scratches when the lens is stored or transported. The case provides padded storage but adds no optical or electronic function.

Questions about this item
How do I attach the Rokinon 85MAFN to my Nikon F-mount DSLR, and what step is often missed?
Align the lens mount index with the camera body index, twist until it clicks, then confirm the automatic chip communicates aperture data to the body — forgetting to verify electronic coupling is the common oversight.
What maintenance will the 85mm f/1.4 lens need over time?
Clean the 72 mm front element and rear glass with a blower and microfibre cloth; the manual helicoid may eventually require re-greasing if focus stiffness appears after extended use.
What limit appears first when shooting wide open at f/1.4 for long sessions?
The shallow depth of field at 85 mm and f/1.4 makes precise manual focus the primary constraint; focus shift on close subjects at 3.3 ft minimum distance becomes noticeable before any thermal issue.
