The Kiev-90 grip is fitted to the camera after first removing the film wind crank knob. The grip then slides onto the plate on the base of the camera and is locked into position with a lever on the bottom of the grip. There is a hot-shoe on the top of the grip which is connected via a lead to the flash socket on the camera. On the top of the grip is a lever-wind that advances the film and cocks the shutter. The shutter relaese button is also at the top of the grip.
