Nikon's updated compact macro — 55mm f/2.8 Ai-S Micro-Nikkor, the refined version of the f/2.5.
The Nikon Micro-Nikkor 55mm f/2.8 is the Ai-S update of the classic 55mm f/2.5 Micro — improved to f/2.8 with Ai-S coupling. It provides 1:2 magnification natively in one of the most compact Nikkor macros ever made.
Optically excellent — sharper than the f/2.5 predecessor with improved coatings. The 55mm provides a near-normal perspective with macro close-focus. 1:2 native — reaches 1:1 with PK-13 extension tube. Ai-S coupling.
Nikon F mount with 52mm filter thread. Very compact — barely larger than a standard 50mm. Ai-S coupling for programmed auto. 1:2 native magnification. Works on Z via FTZ with focus peaking.
Available used at budget to mid-range prices. The updated version of the f/2.5 Micro — sharper with better coatings. An outstanding compact lens for both macro and everyday use. For manual-focus enthusiasts and adapted mirrorless.
