Nikon AF-S Nikkor 60mm F2.8G ED: Nikon’s best Micro Nikkor?By Kevin Carter - Thursday April 24 2014 Lens Review
Nikon replaced the 8-element AF-D version of the 60mm f2.8 Micro with a redesigned model in January 2008. It adopts the firm’s current G-series spec consisting of a built-in sonic type AF motor and a new optical design with a total of 11-elements, including ED (extra low-dispersion) glass and IF (internal focusing). Like its predecessor it has floating elements for improved optical performance at close range and achieves 1:1 (life size) magnification without the use of extension tubes, albeit focusing down to 7.28" (18.49 cm), slightly closer than the 8.66" (22 cm) of the model it replaces.
Despite the inclusion an AF motor and more glass Nikon reduced the weight at 15 oz (425 g) versus 15.52 oz (440 g) yet it adopts the same 62mm filter thread, and measures 2.8 x 3.5" (7.11 x 8.89 cm), slightly longer than the 2.8 x 2.9" (7.11 x 7.37 cm) of the AF-D version. It is available now with an $80 premium over its predecessor at $546.95.
