An update of one the most favorite lenses for most of us...
The new EF 70-200mm f/2.8L IS II USM lens features a revised optical design, incorporating a
fluorite element and no fewer than 5 UD elements for the correction of
chromatic aberrations. The minimum focus distance has been reduced to
1.2m, with a corresponding increase in maximum magnification to 0.21x.
The mechanical design has also been modified, with the most obvious
external change being a wider focusing ring.
