A camera lens assembly, comprising:

• a lens holder for accommodating at least one lens;
• a pin protruding from the lens holder in a radial direction of the at least one lens;
• a ring member with which the pin is engaged, the ring member having a cam groove formed in a spiral direction to have a predetermined pitch along an optical axis and being rotatable about the optical axis according to a user's operation;
• a guide device for guiding the lens holder to move only in a direction parallel to the optical axis,
• wherein when the ring member rotates, the lens holder on which the pin is formed moves in the direction parallel to the optical axis within the pitch under the guide of the guide device;
• and
• a housing for accommodating the lens holder and in which the guide device is installed, wherein the ring member is rotatably coupled to an outer diameter of the housing.
