According to various embodiments disclosed herein, a lens assembly and/or an electronic device including the same may include at least four lenses which are sequentially arranged along an optical axis from an object side to a sensor side, and a tunable lens disposed between two lenses selected from among the at least four lenses and configured such that power or curvature thereof can be changed, wherein the lens assembly may satisfy Conditional Expression 1 below:1.0=<(tun_max)/(tot_min)=<3.0  [Conditional Expression 1]

Lens assembly and electronic device including the same

An electronic device is provided. The electronic device includes a first imaging optical system including a first image sensor, and a second imaging optical system including a second image sensor, a reflective member, a first lens group, a second lens group, and a third lens group, the first, second, and third lens groups being sequentially arranged from the reflective member to the second image sensor, the second and third lens groups being configured to slide with respect to the first lens group, and the first and second imaging optical systems being configured to satisfy a conditional expression SSW/SST>2, where SSW denotes a size of the first image sensor and SST denotes a size of the second image sensor.

Electronic device comprising a plurality of imaging optical systems

According to certain embodiments disclosed herein, a lens assembly and/or an electronic device including the same may include an image sensor, and first to ninth lenses sequentially arranged along an optical axis. The first lens may include a convex object side surface while having positive refractive power, the second lens may include a concave image sensor side surface while having negative refractive power, the third lens may have positive refractive power, and the eighth lens may have has negative refractive power and may include an object side surface and an image sensor side surface, at least one of which is an aspherical surface including at least one inflection point. The lens assembly and/or the electronic device may satisfy Conditional Expression 1: 20≤v3≤40 and Conditional Expression 2: 1.7≤Fno≤2.0. Here, 'v3' may be an Abbe number of the third lens, and “Fno” may be an F-number of the lens assembly. Various other embodiments are possible.

Lens assembly and electronic device including same

According to an embodiment of the disclosure, an electronic device may include a lens assembly including a first lens group having positive refractive power and a second lens group having negative refractive power and an image sensor configured to output an image signal based on light transmitted through the first lens group and the second lens group. A second distance between the first lens group and the second lens group and a third distance between the lens assembly and the image sensor may be configured to be changed based on a first distance between a subject and the electronic device.

Electronic device including lens assembly

An electronic device and a camera assembly are disclosed. The electronic device may include the camera assembly, which in turn may include a lens assembly having at least four lenses, an image sensor, and at least one reflective member that refracts or reflects incident light at least twice, wherein at least one surface of an object-side surface and an image-side surface of a first lens from an object side among the at least four lenses is formed as an aspherical surface, wherein the object-side surface and the image-side surface are formed to be convex, wherein various conditional equations stipulation relationships between back focal length (BFL), effective focal length (EFL) and field-of-view (FOV) are satisfied.

According to various embodiments of the disclosure, a camera module may comprise a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens arranged in order from a subject. The first lens may have positive (+) refractive power and include a 1-1th surface convex toward the subject. The seventh lens may include a 7-1th surface facing the subject and including at least one inflection point. The eighth lens may have negative (−) refractive power, include an 8-1th surface facing the subject and formed as an aspherical surface, and include an 8-2th surface opposite to the 8-1th surface, the 8-2th surface including at least one inflection point and is formed as an aspherical surface. Other various embodiments are also possible.

Camera module and electronic device including camera module with lens assembly

According to certain embodiments, an electronic device comprises a window member; a display panel stacked on a rear surface of the window member; a lens assembly; an iris; and an image sensor including an image plane configured to form an electronic signal representing an image formed by the lens assembly, wherein the iris is fixed with respect to the image plane, wherein at least a portion of the iris is located on a same plane as at least a portion of the display panel, and the iris is located closer to an object-side than an object-side surface of a lens closest to the object-side of the lens assembly on an optical axis.
