Auto Extension Rings
Compact and lightweight, Nikon Auto Extension Rings slide on
and off your camera in seconds for a wide range of reproduc-
tion ratios. Models include the PK-11A, 12 and 13. Lens aper-
ture information is relayed via the PK ring to the camera, result-
ing in an exposure that is determined by TTL full aperture meter-
ing. Exposure modes usable: Aperture-Priority Auto or Manual.
PK-13
Bellows Attachment PB-6
Mounts between the F5 and the lens for close-up and macro
photography. Lets you vary lens extension at the twist of a
knob, for reproduction ratios of 1:1.1 to 4:1 with a normally
mounted 50mm lens. The lens can also be mounted in reverse
to provide aberration correction in the extreme close-up range.
The PB-6 has a stop-down lever so you can use stop-down
metering. Usable exposure modes are Aperture-Priority Auto
and Manual.
