The EF 100-400mm f/4.5-5.6L IS USM is a professional EF mount telephoto zoom lens introduced by Canon Inc. in September 1998. It is a high performance tele-photo lens ideal for sports and wildlife photography which has received high ratings from purchasers at Amazon.com[1] and B&H Photo Video[2] . Photographers using APS-C cameras must apply a crop factor of 1.6x, effectively bringing the focal range to 160-640mm. This is an advantage for crop body users as it is a relatively cheaper alternative to the long prime lenses that cost significantly more.
This lens is compatible with the Canon Extender EF tele-converters on newer EOS bodies. Auto-focus works only on the 1.4× Extender and image stabilizer(IS) works with both 1.4× and 2× Extenders.
