Please read all of the following and only purchase if you understand and agree. Please refrain from bidding if you are unsure about the mount. This is a SIGMA APO 150-500mm F5-6.3 DG OS HSM lens (for Canon EF mount). I am selling it because I have switched to a different mount for my camera body. I was using it until recently, for about two years. Both autofocus (AF) and image stabilization (OS) are working without any problems. The lens appears clear with no dust, fog, or mold when visually inspected. The exterior has some scratches and wear from normal use, but there are no major damages. This lens supports super-telephoto up to 500mm and is suitable for a wide range of subjects, such as baseball, sports events, bird watching, and landscapes. *Instant purchase is welcome and preferred. Please comment if you have any requests. [Condition] ・AF operation: Normal ・OS (Image Stabilization): Normal ・Inside the lens: No dust, fog, or mold ・Exterior: Some scratches and wear.
