Canon has announced three new EF-mount lenses today, bolstering its range of high-end glass with a 24-70mm f/2.8 II USM L-series lens and a pair of 24mm and 28mm wide-angle primes. The 24-70mm is a near-direct replacement for the current lens of the same range, though adds a number of extra features which it promises will improve image quality throughout the range of the zoom. These include a new combination of lens elements and coatings, which should provide improved color reproduction while avoiding ghosting and shape distortion. Also new is a zoom-lock switch, which holds the lens at its widest setting.

The aperture has also been changed, with the old 8-blade mechanism replaced by a new 9-blade setup which Canon promises delivers "incredible bokeh." One noticeable omission is image stabilization — CNET says that it was left out for reasons of "weight, complexity, and expense." The improved optics come at a price, though — the lens is set to launch in April for $2,299, a $1,000 premium over the model it replaces.

IS does make it to the two new wide-angle prime lenses, a 24mm and a 28mm, both capable of apertures up to f/2.8. The primes have ultrasonic auto-focusing, which Canon says delivers smooth and silent operation, perfect for video. Both are expected to launch in June, with the EF 24mm f/2.8 IS USM costing $849.99, and the EF 28mm f/2.8 IS USM running to $799.99.
