The Canon 100-400mm f/4.5-5.6L IS II USM is a spectacular lens that comes in at a hefty price tag; in this instance however you really do get what you pay for if you can afford it. This lens is the most expensive item in our kit at a price of around $1,800 and is quite heavy to carry around but we sure do love using it for landscaping and shooting wildlife. This lens includes a built in 3 Mode Image Stabilization; which works fantastically, a reasonably wide 9 blade f/4.5 aperture at 100mm (f/5.6 @ 400mm), and a razor fast built in Auto-Focus and is without a doubt able to deliver the sharpest images of any lens I’ve ever used.
