Lens apparatus and image capturing apparatus

An image capturing apparatus comprising:

• a lens apparatus including:
• a barrel configured to accommodate a plurality of lenses;
• a first ring arranged around the barrel and configured to rotate about an optical axis;
• a second ring arranged around the first barrel and configured to rotate about the optical axis and move together with the first ring between a first position and a second position in an optical axis direction along the optical axis;
• a friction member arranged between a first surface of the first ring and a second surface of the second ring facing each other, and configured to generate a frictional force on the second ring to cause the second ring to rotate together with the first ring when the first ring and the second ring are in the first position;
• and
• a resistance member configured to generate a resistance force on the second ring to prevent the second ring from rotating together with the first ring when the first ring and the second ring are in the second position;
• and
• an image sensor configured to capture an image formed through the plurality of lenses.
