This is for a MINT Canon EF 50mm STM lens both front and rear lens caps. This lens is in MINT condition and the glass is FLAWLESS. No scratches, no haze, no fungus. The lens is fully tested and working perfectly. Cosmetically, this lens is as-if new. The gripping is clean. The autofocus and image stabilization are working perfectly at all focal ranges. The STM motor is incredibly quiet and awesome! I offer a 30 day no questions asked. Your lens will be carefully packaged and shipped usually within a few hours, and ALWAYS same day.
