Selling a fantastic Sigma 17-50mm f/2.8 EX DC HSM standard zoom lens for Sony A-mount. I previously used this on my Sony Alpha 57, and it is a massive upgrade over the standard kit lens. With a fast, constant f/2.8 aperture across the entire zoom range, it is absolutely brilliant for low-light photography, portraits with blurred backgrounds, and everyday shooting.
​Key Features:
​Constant f/2.8 Aperture: Fast and bright across the entire 17-50mm range.
​Mount: Sony A-Mount (Fits Sony DSLT cameras like the a57, a58, a65, a77, etc., and older Minolta AF cameras).
​HSM (Hyper Sonic Motor): Ensures fast and quiet autofocus.
​Zoom Lock Switch: Features a lock at 17mm to prevent the barrel from extending while walking around.
​Filter Size: Ø 77mm.
​Made in Japan: Premium EX series build quality.
​Condition:
​Used, but in very good working condition.
​The front and rear glass elements are clean and free of scratches.
​The rubber zoom and focus rings show some normal, minor signs of use (typical for Sigma lenses of this generation), but they grip and turn perfectly smoothly.
​Comes with both the original Sigma front cap and the "Sigma for Sony" rear cap.
