Product Description
Allied with a standard zoom you will have most focal lengths you are likely to need The optics of the EF 90-300mm f/4.5-5.6 are based on those of the EF 75-300mm f/4-5.6 III and the optical performance is similar. However, the AF drive pattern has been optimized for the EOS 300V, giving a faster AF speed. Also, a new AF algorithm has been developed. All the lens elements are manufactured from environmentally-friendly lead-free glass. A redesigned electromagnetic diaphragm (EMD) provides an aperture which is nearly circular at the widest settings. This gives an improved out-of-focus background effect. Features: - Compact size and low weight telephoto zoom lens - One of the lenses with the fastest AF speed in its class - Circular aperture at wide settings - Exterior design matches the style of other EOS models - Only environmentally-friendly lead-free glass usedCustomer Reviews:

Product Description
Features Compact size and low weight telephoto zoom lens One of the lenses with the fastest AF speed in its class Circular aperture at wide settings Exterior design matches the style of other EOS models Environmentally-friendly lead-free glass used A good general purpose lens as with the EF 90-300 mm f/4,5-5,6 but including a USM The optics of the EF 90-300mm f/4.5-5.6 USM are based on those of the EF 75-300mm f/4-5.6 III USM and the optical performance is similar. However, the AF drive pattern has been optimized for the EOS 300V, giving a faster AF speed. The communication speed between the lens and the camera is faster due to a new high-speed CPU. Also, a new AF algorithm has been developed. All the lens elements are manufactured from environmentally-friendly lead-free glass. A redesigned electromagnetic diaphragm (EMD) provides an aperture which is nearly circular at the widest settings. This gives an improved out-of-focus background effect. This lens features a micro USM (Ultrasonic Motor) motor which operates almost noiseless.
