Nikon AF-S Micro-Nikkor 40mm f/2.8G DX Macro lens review By Cary Jordan (The Jordan Collective Photography)
The new Nikon AF-S Micro-Nikkor 40mm f/2.8G DX lens has proven to be full of surprises. It was originally announced by Nikon seemingly out-of-the-blue and continues to surprise with its excellent performance. Despite being an affordable entry level macro lens, there is little info out there other than spec sheets and speculation. Having been one of the first to get a copy of the lens, I’ve spent a good deal of time shooting with it.
Since scientific and controlled testing will be carried out by the usual organizations, I will only attempt to show real-world shooting and offer my opinion on my copy of the lens. You can also reference Nikon’s MTF chart for this lens to compliment this review.
All testing was performed on two (2) Nikon D7000 16.2MP DX (APS-C) DSLR cameras.
