The Nikon 105mm F2.8 AIs Micro-Nikkor lens is a band new boxed lens left from old stock Its rare to find such lens any more.

The Nikon 105mm F2.8 AIs Micro-Nikkor lens replaced the decade-old earlier Nikkor classic Micro-Nikkor 105mmf/4.0s. Nikon 105mm F2.8 AIs Micro-Nikkor lens has a full stop faster in its maximum aperture and thus bringing it close to be a all round telephoto-Macro lens. It was debuted as a Ai-S native Nikkor and its immediate benefit is enabling many MF.AF Nikon SLRs be able to use in multi-exposure modes such as Programmed AE and Shutter Priority AE as long as the aperture is stopped down to its minimum aperture at f/32.

Further, the faster maximum lens in Nikon 105mm F2.8 AIs Micro-Nikkor lens speed also provides a brighter viewfinder image where often users complain the previous slower version has caused darkening of the split-image rangefinder in a standard K-type focusing screen in particular when working with a close-up attachment units or with PN-11 at its closest focusing distance. The Nikon 105mm F2.8 AIs Micro-Nikkor lens can be focused down to a minimum distance at 0.47m (1.55ft.) to reach for a reproduction ratio of 1:2 half-life-size magnification. Similar to the slower f/4.0 counterpart, it uses a same PN-11 Auto Extension Ring to enable to almost Nikon 105mm F2.8 AIs Micro-Nikkor lens 1.0X magnification, that is at a minimum focusing distance at from 0.41sm (1.4ft.).

Other than a faster maximum lens speed, the Nikon 105mm F2.8 AIs Micro-Nikkor lens does has some lovely touch in its design. At the side f the Nikon 105mm F2.8 AIs Micro-Nikkor lens, there is a chrome ring that allows you to lock any preset focusing distance. The Nikon 105mm F2.8 AIs Micro-Nikkor lens has a very detail (and colourful) illustrations of various information relating to distance info in feet and meters, reproduction ratio in relation with the lens used in singular and when PN-11 is used in combination engravings on the lens barrel. The rubberized textured focusing grips in rectangular patterns has been extended to six-in-rows from five-in-row used in previous version for a more positive grip and handling during focusing.

Optically, the Nikon 105mm F2.8 AIs Micro-Nikkor lens has revised internally with a more complex 10 elements in 9 groups design to enable it to have a full f-stop increased in its light gathering power as compared to the previous f/4.0 lens. The lens has slightly above average image contrast across its entire aperture range. But resolution is top rated except the two closest maximum apertures, once stopping down to f/5.6 onwards, this lens performs exceptional image quality. Given a faster f/2.8 largest lens aperture, this lens is a top rated all rounder medium telephoto optic which is beyond any normal telephoto lens at medium range focal length can offer as it can extend its working distance all the way down to half life size magnification. This factor alone has made this lens sold incredibly well over the years.
