This is a beautiful item, used a few times for travel, and has been stored in a dry box. The lens mount cap has been replaced with a SONY one. I am selling it to organize my equipment. The TAMRON 28-200mm F/2.8-5.6 Di III RXD is a high-performance zoom lens that covers a wide range of focal lengths, from wide-angle to telephoto. In particular, the bright F2.8 maximum aperture allows for excellent shooting even in low-light conditions.
