Description
Incorporates many advanced and exclusive Canon Lens Technologies to provide improved performance, including the use of two different types of
Aspherical lens elements, and a totally new UD (Ultra-Low Dispersion) glass element for obtaining sharper image quality. Canon's original ring USM (Ultrasonic Motor) makes
autofocusing fast, accurate and silent, down to a reduced minimum
focusing distance of just 15 inches. The Lens is now sealed against dust and moisture
Features
This lens replaces the previous high quality L-series 28-70mm f/2.8 lens, with a
lens of even greater caliber. The range has been extended to cover an ultra-wide angle of 24mm, which makes it ideal for digital as well as film shooters, and the optics are even better than before with two Aspherical elements and a totally new UD glass element. It's now sealed and gasketed against dust and moisture, and a new processing unit makes the AF faster than ever.
• Internal Focusing
The internal focusing mechanism allows the front of the lens to remain stationary and to easily accommodate specialty filters, such as polarizing filters.
• Two Aspherical Elements
A lens design incorporating elements ground so the curve of the surface does not describe an arc of a circle. Especially useful in reducing distortion in wide angle lenses.
• UD Element
UD glass is one of the new technologies to open new possibilities to develop the zoom lenses with low weight and high optical performance. UD elements make it possible to correct chromatic aberrations while maintaining low weight.
