Owner reviews: Nikon AF-S Micro Nikkor 40 mm f/ 2.8 G DX

Period of use: 4 months

  • Ultra sharp edge to edge and at all appertures up to f/11, one of the sharpest lens Nikon has ever made.
  • Light and compact.
  • Ideal for generic use. 
  • It lets you get really close.
  • Neatly geared manual focussing ring allowing fine control of the manual focusing operation.


  • Just one, to get 1:1 macro shots you get your nose on the subject. Inevitably you cast your own shadow to it in many cases.


I have been using a Nikkor 50mm f/1.8 D on my D90 for quite long. Not dealing with low light situations and mostly having it stopped down after f/5.6 to get the sharpest possible output, I began something that would not let me worry about the sharpness in picture taking. The 40mm offers that in a neat package. It is ultra sharp, compact, and it is close to a 50mm on a DX body. It focuses fast and silently and the output is almost free of any distortion.

A great bang for the money!
