  • Canon EF 300mm f/4L IS USM

    10 out of 10 points and recommended
    Excellent sharpness, IS works well, lightning fast AF
    Slow AF with 1.4x TC II

    This lens is my sports shooting lens (soccer). Works great and is wonderful for being able to shoot tight. The AF tracks perfectly in AI Servo with a 5D - allowing one to keep the shutter half pressed allowing the AF to track until just the perfect instant to fire. Rate of keepers is very high.

    With the 1.4x TC II on board, this lens is still a pretty good 400mm f/5.6 lens. However, it is not all that good for sports since the AF is now that much slower - noticeably slow. You can do it but you are going to drop your keeper rate for sports.

    The sliding lens hood is the ticket. Much better than the screw on nonsense.

    Highly recommended.
