This is a ROLAN PRO lens cover with a digital camouflage design for the SIGMA 500mm F5.6 DG DN "E-mount" lens. I purchased it at the end of the year and have only attached it once for test shots. Please understand that this is a used item. This listing is for the lens cover only. Thank you. #WildBirds #BirdPhotography - Brand: ROLAN PRO - Camera Mount: Sony - Color: Digital Camouflage - Lens Type: Telephoto Lens Thank you for looking.
