    摘要： According to one embodiment of the present disclosure, provided, in an electronic device, may be: a lens assembly comprising a plurality of lenses sequentially arranged along an optical axis direction from an object side to an image side; an optical member which is disposed closer to the object side than the lens assembly and is configured to reflect or refract external light incident in a direction crossing the optical axis so as to cause the external light to be incident on the lens assembly along the optical axis direction; and an image sensor. The electronic device may implement a telephoto lens with low chromatic aberration.

    摘要： An imaging system lens assembly includes five lens elements, the five lens elements are, in order from an object side to an image side along an optical path: a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. Each of the five lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The first lens element has positive refractive power, the object-side surface of the first lens element is convex in a paraxial region thereof.

    摘要： A first lens unit performing communication with an image pickup apparatus (10) with a first voltage (V1) and a second lens unit performing communication with the image pickup apparatus with a second voltage (V2) are selectively attached to the image pickup apparatus. The image pickup apparatus includes a controller (18) configured to operate with a third voltage (V3) different from at least one of the first and second voltages to output a signal for the communication with the first and second lens units, and a determiner (90, 20) configured to determine the type of the lens unit attached to the image pickup apparatus. The controller is configured to produce, as a voltage of the signal for the communication, from the third voltage, one of the first and second voltages corresponding to a determination result of the determiner.

    摘要： An optical system (1a, 1b, 1c) includes, in order from an object side to an image side, a front unit (LF) of a positive refractive power, a diaphragm (STO), and a rear unit (LR) of a positive refractive power. The front unit includes, in order from the object side to the image side, a positive lens L11, a positive lens L12, and a negative lens L13. The rear unit includes, in order from the object side to the image side, a negative lens L21, a positive lens L22, and a positive lens L23. A predetermined condition is satisfied.
