Thank you for viewing. I have used this a few times, but haven't had the opportunity to use it much, so it has been stored at home. The rubber parts have whitened slightly, but there are no issues with the operation, and I would be grateful if a new owner could use it, as it can still be used. *A lens protector is also included to prevent scratches on the lens. This is an introduction to the Sigma 17-70mm F2.8-4.5 DC MACRO for Canon EF mount. Sigma lenses have a good balance of image quality and price, and are compact and lightweight lenses that cover a wide-angle 17mm to a medium telephoto 70mm range. Also, it is very bright with F2.8 at wide-angle and F4.5 at telephoto, allowing you to take photos that make the most of the bokeh effect.
