Well, as it is nearlly my birthday, I have bought a new lens. It basically replacing the kit lens that came with my old Canon 350D.24-70mm f/2.8 EX DG MACRO
Large aperture standard zoom lens provides superior performance both for Digital SLR Cameras and 35mm Film SLR Cameras
To achieve an F2.8 aperture at all focal lengths, it employs three aspherical Lens to provide optimum aberration compensation. Two Special Low Dispersion (SLD) glass elements are provided for color aberration compensation, to assure high image quality.
Optimised for digital SLR cameras
It incorporates a "Super Multi Layer Coating" to reduce the influence of harmful light caused by reflections from the digital image sensor.
Excellent correction of aberrations
Two SLD elements, one Glass Mold Aspherical plus two Hybrid Aspherical lenses provide excellent correction of various aberrations and a high level of optical performance.
Minimum focusing distance of 40cm
The lens has a minimum focusing distance of 40cm at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.8.
DF (Dual Focus) System
This lens incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during autofocusing, and yet provides a large focus ring for easy manual focusing.
Petal Type Hood
Since the front of the lens does not rotate, a Petal-type hood and circular polarizing filters can be easily used.
