摘要： A real image mode variable magnification finder has an objective optical system with positive refracting power, an image erecting optical system, and an ocular optical system with positive refracting power. The objective optical system has a first lens unit with negative refracting power, a second lens unit with negative refracting power, a third lens unit with positive refracting power, and a fourth lens unit with negative refracting power. When the magnification of the finder is changed, at least one lens unit, namely the third lens unit is moved. In this way, the total length of the objective optical system can be reduced, and thus a compact finder is obtained.

摘要： The invention relates to an electronic imaging system wherein an image pickup device is horizontally located while ensuring the space for a reflective member thereby achieving height, length and cost reductions. The imaging system comprises a taking lens and an image pickup device. The taking lens comprises a front lens group G1 consisting of a negative lens component and a positive lens component and having positive refracting power and a rear lens group G2 consisting of a negative lens element and a positive lens element and having positive refracting power, with an aperture stop S interposed between the front lens group G1 and the rear lens group G2. The taking lens satisfies conditions (1) and (2).2.8
