Claim:
An electronic apparatus comprising: a level setting member configured to set a level according to operation by a user; a lock member configured to engage with the level setting member so as to lock the operation of the level setting member when the user performs operation to bring the lock member into a lock state; a detection unit configured to detect that the lock member is operated to be brought into the lock state before the lock member engages with the level setting member; and a control unit configured to fix the level to a level set by the level setting member at the time the detection unit detects that the lock member is operated to be brought into the lock state, and invalidates the setting of the level by the level setting member when the detection unit detects that the lock member is operated to be brought into the lock state, wherein the control unit maintains the level fixed by the level setting member until the detection unit detects that the lock member is operated to release the lock state and the level setting member is operated, and wherein the control unit releases the level fixed by the level setting member when the detection unit detects that the lock member is operated to release the lock state and the level setting member is operated.
