Review of the Nikon Micro-Nikkor 55mm 1:2.8 Ai-S Lens (f/2.8).
This lens was introduced in 1979 and therefore is 44 years old. Almost half a million copies have been produced.
This little lens is a great performer even for today's high resolution digital cameras.
Unlike its earlier cousin, this lens is quite sharp for both macro shots and distant shots near ∞ thanks to its close-range-correction (CRC). But becareful when using the PK-13 27.5mm extension tube to go to 1:1 because the lens must be extended/focused to its max to make sure that its [CRC] elements are aligned for maximum sharpness for near subjects. So do not use this extension tube and only focus to 1:2.
This lens is NOT great for infrared photography as it demonstates a strong hotspot at smaller apertures.
The bokeh is fair. There does appear to be a very small amount of LoCA.
This lens stops at infinity (∞) focus, and the focus throw is a nice, long 310° (for critical-focusing).
The quality of this manual focus lens is something to behold. The focus has a nice fluid resistance and each click of the aperture ring is very positive. These copies have 744### and 729### serial numbers and feel great to use. This lens has a reputation for having oily diaphragm problems which cause the diaphragm to move slowly, too slowly to properly expose the digital camera sensor at the expected exposure. None of these copies exhibit this problem so there are good copies available, just be sure to check this problem before purchase. A Nikon Nikkor lens diaphragm should be described as "snappy" which indicates that there is no oil and it is functioning properly.
Generally, this lens impresses when used with teleconverters
