Abstract: A camera with a varifocal objective is equipped with an indicator which signals the existence of a condition unsuitable for the taking of pictures because of the risk of blurring, especially when the camera is held by hand, as where a large focal length is chosen together with a long exposure time. The indicator is overridden upon reduction of the risk by certain precautionary measures, including the use of a self-timer which generally involves placement of the camera on a stable support.
Abstract: A camera of variable focal length is equipped with an indicator which signals the existence of a condition unsuitable for the taking of pictures because of the risk of blurring. The indicator is controlled by a sensing circuit taking into account such parameters as focal length, exposure time and, possibly, the steadiness of the camera support.
