Nikkor 28mm f/2.8 AI-S is Nikon's moderate wide-angle prime in the AI-S manual-focus lineup — the most-sold Nikon wide-angle prime in the manual-focus era. The 28mm focal length on 35mm provides a "wide but natural" perspective that suits street, documentary, and environmental work without the dramatic perspective distortion of true wides.
