Nikon 28mm f/2.8 [AI-S]
This is Nikon's best 28mm design. It has been in production since 1981 and often sells for more on the second hand marked than its auto-focus successors.
This lens has a sophisticated 8-element optical formula with CRC (Close Range Correction) that make it very well suited for close-up photography. The sweet spots for close-up is at f/5.6 and f/8. For more distant scenes, however, corner sharpness is less impressive. It is not immune to flare and ghosting. CA and vignetting is well controlled, even on FX.
Not suitable for IR-work, as it produces a hard to correct hot-spot.
Uses screw in lens hood HN-2.
