Abstract: An imaging lens includes, in order from the object side to the image side, a positive first lens group, a stop, a positive second lens group, and a positive third lens group. The first lens group includes, consecutively in order from the most object side thereof, a negative lens and a positive lens. The second lens group is of a three lens configuration and includes a positive lens and a negative lens. The third lens group includes, consecutively in order from the most object side thereof, a negative lens and a positive lens. The imaging lens satisfies Conditional Formula (1): 0

Abstract: The zoom lens includes, in order from a position closest to an object side to an image side: a first lens group that has a positive refractive power; a second lens group that has a negative refractive power; an intermediate group that has a positive refractive power; and a subsequent group that has a negative refractive power. The first lens group moves during zooming. The second lens group consists of, in order from the object side to the image side, a front group of the second lens group which does not move during image blur correction and an image stabilization group which moves during image blur correction and has a negative refractive power. The zoom lens satisfies predetermined conditional expressions.

Abstract: The zoom lens consists of, in order from an object side to an image side, a first lens group having a negative refractive power, a middle group, and a final group. During zooming, a spacing between the first lens group and the middle group changes, and a spacing between the middle group and the final group changes. During focusing, at least a part of the middle group moves, and the first lens group and the final group remain stationary with respect to an image plane. The zoom lens satisfies predetermined conditional expressions about a back focal length, a focal length, and a maximum half angle of view.

Abstract: A lens unit includes a guided portion that includes a first bearing portion and a second bearing portion disposed to be spaced apart from each other in a direction X and is slidably supported by a guide shaft, and a lens holding member. The lens unit includes a first tilt-preventing member having a linear expansion coefficient lower than a linear expansion coefficient of the lens holding member. The first tilt-preventing member is fixed to a region of the guided portion positioned between the first bearing portion and second bearing portion.

Abstract: The imaging lens consists of, in order from an object side, a positive first lens group, a positive second lens group, and a negative third lens group. During focusing, only the second lens group moves. The number of lenses included in the second lens group is two or less. The lens on the most object side is a negative lens having a convex surface toward the object side. The lens surface on the most image side is a convex surface. The first lens group includes a stop. Predetermined conditional expressions related to the first lens group and the second lens group are satisfied.

Abstract: The zoom lens consists of, in order from the object side, a first lens group that has a negative refractive power; a second lens group that has a positive refractive power; a third lens group that has a negative refractive power; and a fourth lens group that has a positive refractive power. During zooming, in each lens group, distances between the adjacent groups in the direction of the optical axis are changed. The first lens group consists of, in order from the object side, a first lens having a negative refractive power, a second lens having a negative refractive power, and a third lens having a positive refractive power. The third lens group consists of a negative lens. During focusing, only the third lens group moves along the optical axis. The zoom lens satisfies predetermined conditional expressions.

Abstract: A lens unit includes a guided portion that includes a first bearing portion and a second bearing portion disposed to be spaced apart from each other in a direction X and is slidably supported by a guide shaft, and a lens holding member. A first distance between the center of a fixing portion of the lens holding member and the center of the first bearing portion in the direction X is set to be longer than a second distance between the center of the fixing portion and the center of the second bearing portion in the direction X. A first tilt-preventing member having a linear expansion coefficient lower than that of the lens holding member is fixed to a region, which is closer to the first bearing portion than the center of the fixing portion, of a portion of the guided portion positioned between the first and second bearing portions.
