The SIGMA 18-250mm F3.5-6.3 DC OS lens features optical stabilization and covers a wide focal length range. For SONY Alpha A-mount. Includes lens hood. I haven't used it in recent years and have been storing it, but there is an unusual noise coming from the focus motor. The noise lessens slightly with continued use, but the motor's movement is poor and focusing takes time when moving focus significantly from near to far distances. It moves to some extent when focusing within a close range. Please consider this lens for still photography or for those who can replace the motor themselves. Some dust may be present inside the lens, but in my amateur opinion, it doesn't seem to affect the image quality. I am selling this as a defective item, so please consider this before purchasing. Returns and claims after receipt are not accepted. - Brand: SIGMA - Model Name: 18-250mm F3.5-6.3 DC OS - Optical Stabilization: Yes - Focal Length: 18-250mm - Aperture: F3.5-6.3 - Switch: AF/MF - OS Switch: ON/OFF Thank you for viewing.
