Canon EF 70-200mm f/2.8L IS II USM
Jan 5, 2010 Camera Lens
The EF70-200mm f/2.8L IS USM was introduced in 2001. Ever since, it has been the high performance telephoto zoom lens of choice of most professional and advanced photographers because of the value it provided in the various fields of photography such as photojournalism and sports photography. The EF70-200mm f/2.8L IS II USM is an upgrade of the older model. It is designed with higher quality optics and it is designed to sustain tough weather conditions.
A large diameter f/2.8 lens offering telephoto 70-200mm focal range, the EF70-200mm f/2.8L IS II USM offers premium build quality expected of a Canon L lens, with four-stop image stabilization, minimum focus distance of 1.2m over the entirety of its zoom range, and a combination of flourite and UD lens elements for best quality images.
Higher optical performance
Compared to the older models, the EF70-200mm f/2.8L IS II USM consists of at least 23 lens elements in 19 groups. This means that this new lens offers greater image quality throughout the whole zoom range.
The flourite lens element used in this lens cuts the chromatic aberration (both axial and magnification type of chromatic aberration) to a minimum. Coatings and lens disposition have been optimized to cut flare and ghosting.
Excellent Performance: High Speed AF, 4-stop IS
Its ring USM drive and high speed CPU with improved AF algorithm offers fast and quiet auto focusing. The ultra-compact stepping motor (USM) and friction-reducing mechanisms has been incorporated in this lens. These innovations give the lens 4-stop advantage with IS switched on. The lens also features manual focusing.
Reliable in tough conditions
The EF70-200mm f/2.8L IS II USM features a magnesium alloy construction for its main components. The fixed barrel has been strengthened. Water proofing and dust has been improved to make the use of the lens suitable in harsh weather conditions.
