Canon has today announced an interesting new constant aperture ‘digital’ (EF-S) lens. The new EF-S 17 – 55 mm F2.8 IS is designed specifically for the dimensions of a ‘cropped sensor’ (1.6x crop) and hence can be made smaller than a 35 mm equivelant lens. It features a maximum aperture of F2.8 throughout the zoom range which means it’s a faster alternative to other EF-S lenses. On an EOS 30D this lens would provide a 27.2 – 88 mm equivelant field of view. This lens should be available in May for approx. $1150.
