摘要： The present invention provides a wide-angle lens capable of obtaining a suitable negative power even when a thickness of a first lens is increased in order to increase strength against impact. The wide-angle lens 100 has a front group 110, an aperture 80, and a rear group 120. Assuming that a central thickness in an optical axis direction of a first lens 10 is T1 (mm) and a focal length of the entire lens system is f0 (mm), the following conditional expression:

1.500≤T1/f0≤2.000  Conditional expression (1)

is satisfied. Therefore, it is possible to suppress the first lens 10 from being damaged by impact. In addition, it is possible to prevent the first lens 10 from becoming too thick to obtain suitable negative power.

摘要： A lens barrel includes a plurality of lens groups (1, 2), lens frames (1a, 2a) to hold the plurality of lens groups, respectively, a lens driving apparatus to drive the plurality of lens frames and a fixed member (5) to hold the lens driving apparatus. The lens driving group includes a rotational member (6) which is forwardly moved while rotating relative to the fixed member (5), a linearly moving guide member (7) which moves with the rotational member (6) in the optical axial direction while limiting rotation of the lens frames and is not capable of rotating, and a linearly moving-guide biasing member (8) which is capable of moving in the optical axial direction relative to the linearly moving guide member and is configured to limit rotation. The linearly moving-guide biasing member has a resilient structure configured to bias the linearly moving guide member in the optical axial direction.
