Canon EF 100-400mm f4.5-5.6L IS USM

The Canon EF 100-400mm f/4.5-5.6L IS USM telephoto zoom lens is a top quality professional lens with the highest focal point available with its 400mm maximum zoom. You can take images from far away with nearly perfect clarity up to over a mile away in some instances when the weather permits it. This lens is not meant to take photos of subjects less than about six feet away however because its focal range begins at 100mm.

The lens construction is made up of 17 elements in 14 different groups. You really can’t beat the construction quality of the L series telephoto zoom equipped with built in image stabilization technology that is superior to most others on the market. It is also made to be compatible with the 1.4x II and 2x II extenders. This lens also works with both digital and 35mm film camera bodies. It is made of higher quality materials than most lower priced lenses. It is constructed mostly of quality metal and high impact plastic making it a bit on the heavy side which is the only downside there really is to this lens(its heavy weight). Don’t forget, heavier lenses are usually better made and more durable. So, even though lightweight lenses may be more convenient and easier to carry around, they are likely not to last nearly as long as the heavier, better made professional lenses such as this one.

If you want a real professional quality telephoto zoom lens for taking far away pictures and you can afford the high end price of the Canon EF 100-400mm f/4.5-5.6L IS USM telephoto zoom lens, than this is the lens for you, just remember you would have to switch lenses if you needed to take a shot of a subject that is much closer to you than six feet or so.

All in all, this is a great telephoto zoom lens with Canon’s well perfected image stabilization system and auto focus mechanisms. Fluorite and Super UD-glass elements help to eliminate image flaws caused by the secondary spectrum. High image quality is possible at all focal points with this lens do to the floating system it utilizes. This is a super high quality professional telephoto zoom lens that would be a great addition to anyone’s lens collection that use Canon EOS camera bodies. It also works with extenders like the 1.4x II and 2x II.
