SLR Gear has a comprehensive review of the Nikon AF-S Nikkor 85mm f/1.4G lens. For your info, this prime lens was announced in August of 2010. The lens features a constant f/1.4 aperture, and was designed to fit the 35mm film frame or FX imaging sensor. Mounted on a DX-sensor body, the lens produces an effective field of view of approximately 127mm. The lens features an AF-S motor, which enables it to be used on SLR camera bodies, which don’t have an Auto Focus motor. Here is the verdict:
Edge-to-edge sharpness is radically improved in the G version of the 85mm f/1.4, when compared to the D version. However, the $1,700-question: is this an improvement? The 85mm f/1.4D was for many, the go-to portrait lens, and in part, this was because of the corner softness produced by the lens at f/1.4. The new version of the lens removes this factor, and unfortunately, doesn’t produce super-sharp results at f/1.4 for the trouble. Rather, we see 2-3 blur units across the frame (on the D3x) with a slight “sombrero” effect. Lastly, longitudinal chromatic aberration is (still) a factor when the lens is used at large apertures, producing red fringing in front of the focal plane, and green fringing behind it.
The Nikon AF-S Nikkor 85mm f/1.4G lens is currently available for approximately $1,700. Each purchase comes equipped with a round hood. [SLR Gear]
