Going Wide(ish): Nikkor 20mm f/3.5 AI

The circa 1980 Nikkor 20mm f/3.5 AI lens comes with a reputation for being flare resistant and reasonably sharp as well as being very lightweight.



Nikon have failed to produce a (effective) wide and lightweight prime for their DX systems and the 20mm f/3.5 AI can potentially fill this gap (giving a 35mm equivalent FOV of 30mm) with the added benefit that the lens would not overlap with any 24-70mm focal lengths.
