It's a thingie visible inside the body's mount that lets you use open aperture metering on any lens with an aperture ring. Almost all film bodies had this feature, and many permited both metered manual and aperture priority shooting modes with such lenses.
Absence of this thingie on the DLSRs means you can only use stop-down metering with K/M lenses.
