Canon EF 90-300mm f/4.5-5.6 USM Lens 35mm Zoom
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.

Weaknesses: Unacceptable sharpness over 200 mm. Revolving front part. Plastic bayonet.
This lens was my first long telezoom and after some month of tests and experiments i was disappointed. In the range 100-200 mm is not to bad, sharpness, contrast and colours are enough, but in the range 200-300 mm its sharpness I can't accept. Maybe for other photographer it would be acceptable, but for me setting 300mm is most important, because my main subject is nature. I think, that its drawbacks are typical as for all unexpensive long telezooms of Canon (f.e. all 75-300).
