Since the 85/3.5 doesn't have the "IF" designate, meant the lens barrel will extend when focusing?
you are wrong it's tue IF internal foucsing, everything same as AFS 105mm.
maybe you only know AF-D & tamron SP 90 all are extend focusing.
This Nikon AF-S DX Micro NIKKOR 85mm f/3.5G ED VR Lens is a DX-formatted medium telephoto Micro lens. It is ideal for extreme close-up and general photography including portraits. The lens will autofocus from infinity to 10.8" producing a life-size (1:1) image.
The lens also features Nikon's VR II (Vibration Reduction) image stabilization. This allows handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper images. This is ideal for macro close-up work.
