This is for a Canon 28-105mm USM lens with both front and rear lens caps. The lens has an aperture range of 1:3.5-4.5. Overall this lens is in GREAT condition, and the glass is very well made on these USM lenses. The focusing motor is super quite, and the lens is 100% fully functional. The gripping has some wear (slight discoloration). The lens has no haze, no fungus and no significant dust.
