With an internal focusing system and minimum focus distance of 5.6 metres in AF mode, this lens excels at capturing detailed images of distant subjects. The rugged magnesium alloy body, integrated tripod collar with removable feet, and internal focusing mechanism provide the durability and handling characteristics professionals demand. Though discontinued and no longer in production, this lens remains a highly sought-after instrument for photographers who value legendary Nikon optical quality and precision engineering.
