The 200mm Micro-Nikkor AI-S 1:4 IF is a telephoto lens that can focus as close as 2⅓ feet (61cm) while reproducing a 1:2 image on film or a full-frame sensor. In this review, I’ll explain what this lens is for, how it came to be, and what its modern analog is. Expect lots of samples, a full recollection of what it’s like to shoot, and whether you should get one, too.
