Canon Lens EF 100-300 mm 100-300 mm 1:4.5-5.6 USM Ultrasonic Zoom Lens

Canon Lens EF 100-300 mm 100-300 mm 1:4.5-5.6 USM Ultrasonic Zoom Lens AF is fast and quiet. The Canon EF 100-300mm f/4.5-5.6 USM Lens utilizes Ring USM (Ultrasonic Motor) focusing, and FTM (Full Time Manual) focusing is an included feature. The MF (Manual Focus) ring is small and wobbly - It is not as easy to use as it could be. The zoom ring, on the other hand, is too easy to use. The 100-300 will extend all by itself when hanging downward. At 1.2 lbs, the 100-300 is a mid-weight lens. It feels substantial in your hand. s/n - 27007531
