Overview

The Nikon AF-S DX Micro Nikkor 40mm F2.8 is a compact, lightweight macro lens for DX cameras, offering a 1:1 reproduction ratio and a 60mm equivalent field of view. Optically, it delivers high resolution and contrast from infinity to life-size, though its short focal length requires very close working distances, which can block light and scare subjects. Build quality is solid with a metal mount and smooth manual focus override. Autofocus is quiet and accurate, but slows in macro range. It suits DX users wanting an affordable normal lens with macro capability, but serious macro shooters should consider longer options.
