摘要： A zoom lens (101) includes, in order from an object side, a first lens group (F) of which at least a part moves for focusing, a plurality of lens groups (LZ) which moves in zooming, an aperture stop (SP), and a final lens group (R) which does not move for zooming. The final lens group (R) includes a separation element (PR) for separating an incident light thereon into a transmitted light and a reflected light, a relay unit LR having a positive refractive power on which the transmitted light is incident, and a relay unit LA having a positive refractive power on which the reflected light is incident. An inequality about Fwp/Fw is satisfied, where Fw is a focal length at a wide angle end of the zoom lens (101) via the relay unit LR and FwP is a focal length at the wide angle end of the zoom lens (101) via the relay unit LA.

摘要： A telephoto lens unit (1) having a lens barrel that supports a telephoto lens and capable of being mounted on and dismounted from a camera body (16) comprises a front lens barrel section (11) that supports the telephoto lens with the subject side defined as the front, and a rear lens barrel section (13) that can be mounted on and dismounted from the front lens barrel section. The distance from the image-most surface of the telephoto lens to the image formation plane of the telephoto lens is kept sufficiently long. Converter lens units (12, 14) for elongating or shortening the focal distance are mounted on the front lens barrel section (11) instead of the rear lens barrel section (13) to provide interchangeable telephoto lenses for a camera having different focal lengths. Also, an erecting prism unit (15) and an eyepiece unit (17) can be connected instead of the rear lens barrel section to enable the telephoto lens to function as a terrestrial telescope.
摘要翻译：具有支撑长焦镜头并能够安装在照相机主体（16）上和从照相机主体（16）上卸下的镜筒的长焦镜头单元（1）包括：前透镜镜筒部（11），其支撑被摄体侧限定的远摄镜头以及可以从前镜筒部分安装和拆卸的后镜筒部分（13）。从长焦镜头的最上表面到长焦镜头的图像形成面的距离保持足够长。用于延长或缩短焦距的转换器透镜单元（12,14）代替后透镜镜筒部分（13）安装在前镜筒部分（11）上，以为具有不同焦距的相机提供可互换的长焦镜头。此外，可以连接直立棱镜单元（15）和目镜单元（17）来代替后透镜筒部分，以使长焦镜头能够用作地面望远镜。
