Canon EF 100-300mm f/4.5-5.6 USM Telephoto Zoom
*Perfect working condition with front/back caps
*The Canon EF 100-300mm f/4.5-5.6 USM Lens is a mid-grade long telephoto zoom lens.It is built reasonably well. A metal lens mount shows that the 100-300 is not a bottom-of-the-line lens.
AF is very 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 very small and wobbly.
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.
