    摘要: The lens apparatus allows adjustment of lens tilt due to component variation caused by tolerance. The lens barrel includes a straight guiding barrel having a straight groove portion, a cam barrel having a cam groove portion, a straight movable barrel disposed outside the straight guiding and cam barrels, holding a lens and being movable in an optical axis direction by a relative movement of the straight guiding and cam barrels. A cam follower includes first and second cylindrical portions that respectively engage with the straight groove and cam groove portions. The first and second cylindrical portions have central axes decentered from each other. The cam follower includes an operation portion allowing rotational operation of the first and second cylindrical portions from outside of the straight movable barrel. A connecting member connects the cam follower and the straight movable barrel with each other.
