摘要： A lens barrel and a camera system are capable of precisely calculating a photographic magnification and a field range. The lens barrel having a focusing or zooming movable lens unit is stored with effective focal length data corresponding to a position of the movable lens unit, detects the position of the movable lens unit, outputs the corresponding effective focal length data and calculates the photographic magnification and the field range. An accuracy of a calculated value is thereby enhanced enough not to cause an underexposure on the whole or the underexposure in a peripheral portion as compared with a central portion.

摘要： At a lens group position storage unit, the positions of a focus lens group and a zoom lens group detected at the time of a preset operation are stored. In response to an instruction for a go-home operation, a zoom lens group position comparison unit compares the current zoom lens group position with the position detected at the time of the preset operation. If the zoom lens group position assumed when the instruction for the go-home operation is issued is further toward the telephoto side relative to the zoom lens group position at the time of the preset operation, a defocus prevention unit issues a warning so as to prevent defocusing.

摘要： An automatic focusing device for a camera capable of accommodating an interchangeable zoom lens which prevents inadvertently performing a moving subject tracking lens drive control when the zoom lens causes focus shift as a result of a zooming operation. The automatic focusing device operates in a first drive mode in which movement of the subject in the optical axis direction is detected and the moving subject is tracked by providing compensation for the drive amount of the lens according to the movement of the subject, and a second drive mode in which movement of the subject in the optical axis direction is not detected and compensation for the drive amount of the lens is not provided. A determination that the zoom lens causes focus shift during a zooming operation is made when the object distance is within a specified distance range, and a focus shift signal is output when focus shift will occur. An inhibition device inhibits the lens drive in the first lens drive mode in response to the focus shift signal.

摘要： A camera system and a rear conversion lens both of which accurately calculate the distance .DELTA.X a focusing lens moves when the rear conversion lens is interposed between an interchangeable lens and the camera body, even when the distance .DELTA.Bf an image surface of the focusing lens shifts, increases, so that a subject can be focused quickly.A factor K.sub.0 for converting the distance the image surface of an interchangeable lens shifts and a factor C.sub.0 for correcting the conversion factor K.sub.0 are stored, and the magnification .beta.c and the focal length fc of the rear conversion lens are also stored independently of the above two factors. The distance .DELTA.X is calculated with precision. The subject can thus be automatically focused smoothly and quickly.

摘要： Signal transmission device in an intermediate lens barrel comprises a signal surface, a first inclined surface and a second inclined surface. When the intermediate lens barrel is connected to an objective lens, the signal surface gets in engagement with a signal member on the objective lens barrel and is shifted in the direction of the optical axis. When the intermediate lens barrel is rotated to connect it to a camera, a signal detection member on the camera is guided to the signal surface by the first inclined surface. The second inclined surface guides the detection member to a reference surface on the intermediate lens barrel when the latter is rotated in the direction to disconnect the barrel from the camera.
