What the chambers of the Nikkor 50mm f / 1.2 m S lens Amnesty International? What exactly does "metro" mean?
Is it fair to say to pick your own aperture and shutter speed? Which means I basically have to shoot in manual mode all the time this goal at least?
This means that the meter is coupled (either manually or electronically) to the lens. Here is a letter of support for http://www.nikonians.org/nikon/slr-lens.html Nikon.
