Rounded nine-blade diaphragm produces a pleasing out-of-focus quality when working with shallow depth of field techniques. Additionally, a fluorine coating has been applied to the front lens element to repel water, fingerprints, and smudges for easier cleaning of the lens surface. Moisture-resistant construction incorporates seals around the lens mount and other areas to benefit working in inclement conditions.

This motor also enables full-time manual focus control without having to shift into a dedicated MF mode.Ī Floating System is employed that moves a single group of elements to control focus in order to provide faster AF response as well as a minimum focusing distance of 11.4" and maximum magnification ratio of 1:3.4 for enhanced close-up shooting. Ring-type USD (Ultrasonic Silent Drive) motor is employed for fast, precise, and quiet autofocus performance that benefits both stills and video recording. VC (Vibration Compensation) image stabilization is incorporated into the lens' design to minimize the appearance of camera shake for sharper handheld shooting in low-light conditions. Two aspherical elements correct for spherical and comatic aberrations, as well as distortion, for consistent edge-to-edge sharpness and illumination throughout the aperture range, as well as a reduction of sagittal comatic flare.ĮBAND (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) coatings have been applied to lens elements to reduce surface reflections and prevent lens flare and ghosting for increased contrast and color accuracy.
One LD (Low Dispersion) element helps to minimize chromatic aberrations in order to achieve greater clarity with reduced color fringing. A normal-length prime, this 45mm lens is designed for FX format Nikon F mount DSLRs, and is also compatible with DX models where it will provide a 67.5mm equivalent focal length.įast f/1.8 maximum aperture benefits working in low-light conditions and also avails selective focus control.
