|Canon EF 100-400mm f/4.5-5.6L IS lens|
There is a highly-rated merchant on the Internet selling the Canon EF 100-400mm f/4.5-5.6L IS lens for $999 including free shipping. Although this lens has been out since 1998, it is still a top performer and one of my favorite Canon 'L' zoom lens for a wildlife photographer.
I have taken this lens all around the globe on photo shoots, from the high Arctic to the Southern Ocean. The replacement Series II lens was announced in November, 2014. Read my comprehensive review of the new lens and see my lens recommendation for nature and wildlife photography.
