佳能博物馆之二，经典变焦Canon nFD35

前期介绍了Canon R 135mm f/2.5 （传送门）, 得到众兄弟的支持捧场，决定再接再厉推出第二期，为大家介绍一下FD时代的一只经典变焦：Canon nFD35-105mm f/3.5。

虽然平常是玩定焦为主的，但是出去玩什么的总还是觉得一只定焦无论如何也有焦段力不从心的时候，在撸齐双机双定的配置之前，一只变焦还是必须的。个人而言驾驭广角总觉的功力不够，又比较喜欢玩中长焦，所以这个35-105的古董焦段反倒是比较适合我，全焦段恒定光圈，再加上微距模式，使这只镜头具备了一定的可玩性。

首先，引用佳能博物馆网站的资料介绍一下技术参数 (下面这张是不是有点像18-105G

)：

Canon FDn 35-105mm f/3.5 zoom lense

With a moderately high zoom ratio of 3x covering a focal length range from 35mm to 105mm, the lens permits flexible selection of angle of view and perspective. Aberration fluctuations common to zoom lenses employing 4-group zoom mechanisms have been greatly corrected.

The lens maintains a relatively large maximum aperture of f/3.5 throughout the zoom range. A macro mechanism permits close-ups at its extreme 35mm focal length end with a minimum film-to-subject distance of 30cm.

Compact and lightweight, it weighs only 600 grams and it zooms over a broad range of focal lengths, from wide-angle to intermediate telephoto.
