ABSTRACT:
A lens barrel comprises a first lens group and a second lens group. One of the first lens group and the second lens group is mounted on a lens barrel body with an adjusting mechanism for lens axis deviation intervening therebetween. The other set of lens is mounted on the lens barrel body with an adjusting mechanism for lens inclination intervening therebetween. Adjustments for axis deviation and inclination of the lenses are thereby facilitated.
