Trigger advance is the name applied to a film advance intended to be pulled by the photographer's forefinger, rather than the more common thumb-operated rapid wind lever. Typically this is a lever which can be extended from the baseplate of a camera, although other possibilities include a lever mounted on the front of the camera, as used in the Konica III. By allowing a photographer to keep his or her eye to the viewfinder while winding, a trigger advance allows sequence shooting nearly as rapid as with a power winder.
Notable cameras using a trigger-wind lever include the Canon VT and VI-T; the soviet Drug, and the Ricoh 35 and 500.
