Micro Nikkor AF-S DX 40mm f/2.8 G (CX) - Review / Test Report
25 September 2011
Conclusion: Since the lens is designed for a larger sensor, distortion and vignetting are no issues on Nikon 1 cameras. CAs are a bit pronounced at small apertures, but can easily be taken care of in post processing.
Micro Nikkor AF-S DX 40mm f/2.8 G - Review / Test Report
23 September 2011
Conclusion: The build quality of the lens is good and in line with other affordable prime lenses, like the AF-S DX 35/1.8 or AF-S 50/1.8 G. The only real issue here is the amount of play in the focus ring. Although the lens is sonic wave driven, the AF is not really a speed demon.
