摘要： PROBLEM TO BE SOLVED: To enhance the operability of a photographic camera equipped with a pseudo zooming function, and to attain the variance of a way to use the pseudo zooming function. SOLUTION: By operating a zoom lever 6, a zoom finder 22 is varied among one-power and four-power, then, the finder image is observed in accordance with the variable power rate. The photographic lens 8 is varied between one- power and two-power. Plural kinds of distribution data with the combination of the variable power rate of the photographic lens 5 and the pseudo zooming magnification in accordance with three kinds of programs with respect to the variable power rate of the zoom finder 22 are stored in a distribution data memory 38. In the case of selecting one of the programs by a switching lever 27, the distribution data combined based on the selected program are read out in accordance with the variable power rate of the zoom finder 22, then, the variable power rate of the photographic lens 5 is decided, and also, the pseudo zooming magnification is decided.

摘要： PROBLEM TO BE SOLVED: To confirm an operability and a zooming effect in a satisfactory state, as for a camera capable of pseudo-zoom photographing. SOLUTION: By operating a zoom lever, the magnification of a finder is varied between the minimum finder magnification α=1 capable of observing a photographing range corresponding to the shortest focal distance f1 of a photographic zoom lens and the maximum finder magnification α=4 capable of observing the photographing range corresponding to a pseudo longest focal distance which is obtained by multiplying the longest focal distance f2 by the maximum value of the pseudo zoom magnification. The real focal distance of the photographic zoom lens and the pseudo zoom magnification β are decided by a controller in accordance with the finder magnification α. In the case the finder magnification α is within the extent of 1 to 2, the real focal distance of the photographic zoom lens is controlled so as to correspond to the finder magnification α within the extent of the shortest focal distance f1 and the longest focal distance f2, and also, the pseudo zoom magnification β is controlled to be '1' which shows that the pseudo zoom photographing is not executed. In the case the finder magnification a becomes >2, the photographic zoom lens is fixed at the longest focal distance, and the pseudo zoom magnification β is decided by satisfying α=(f2/f1).β.

摘要： PROBLEM TO BE SOLVED: To obtain a photographic camera capable of accomplishing high image quality photographing with a zoom lens, preventing the degradation of the image quality of a print at the time of using a pseudo zooming function, and by which a photographer can take a picture without being conscious of the pseudo zooming function. SOLUTION: Within the extent of the maximum variable power rate of the zoom lens, only the zoom lens optical system is operated, and when a zooming lever is operated beyond the maximum variable power rate of the zoom lens, the pseudo zooming function is actuated. As for the variable power rate of the zoom lens when the pseudo zooming function is in use, the variable power is moved backward and forward near the maximum variable power, and the pseudo zoom magnification is set so that the overall magnification may be continuously increased little by little so as to compliment the variable power of the zoom lens. The variable power rate of the finder is smoothly shifted in accordance with the overall magnification so that the photographer may not be conscious of the pseudo zoom magnification.

摘要： PROBLEM TO BE SOLVED: To execute photographing at photographing magnification intended by a user and to realize miniaturization and the reduction of the cost. SOLUTION: By driving a single zoom motor 55 in response to variable power operation from a variable power operation part 45, the driving is inputted in a finder optical system variable power mechanism 53 and a photographing optical system variable power mechanism 51 so as to perform variable power by linking a finder optical system 10 and a photographing optical system 34. The mechanism 53 makes the optical system 10 perform the variable power so as to obtain a field range matched with an image plane range corresponding to pseudo zoom magnification. The mechanism 51 is set so that the zoom magnification of the longest focal distance of the optical system 34 may be smaller than the zoom magnification in the case of the longest focal distance of the optical system 10 and makes the optical system 34 perform the variable power so that the zoom magnification may be gradually increased from the shortest focal distance to the longest focal distance.
