Query: prime-quality images in a convenient zoom package

My all-around favorite lens in the Canon EOS system is the 50/1.4. I find that most of the time, most of the pictures I want to take can be achieved using hte 50mm focal length, and the fast aperture allows me to take photos in low light.I bought the 24-70/2.8 in hopes of getting high quality images from a zoom lens, as a lot of my pictures weren't in particularly dark places, and the flexibility to get a little wider or closer sounded appealing.I was not disappointed.The image quality produced by the 24-70/2.8 is outstanding. Great color, great sharpness. It might not make images quite as striking as Canon's 135/2 lens, but they are very good indeed.Does this lens replace the 50/1.4? No way. The 50 is a lot smaller, weighs a lot less, and is still much better for low light shooting. But for photographing events where you don't want to lug around several prime lenses or go to extreme lenghts to frame the shot better, the 24-70 can be a great tool.
