Here’re the comments from PopPhone: “Sports shooters and photojournalists may not use the Live View mode very often, but portrait, nature, and architectural photographers will find it convenient. The AF system doesn’t work in Live View mode, but the 5X and 10X zoom function lets you manually focus precisely on macro subjects without interfering with ambient light.

We also liked the function that darkens or lightens the display to mimic exposure settings. But beware: Live View runs down the battery (CIPA ratings drop from 2200 to only 350 shots).

In all, if you’re a pro who craves speed and can’t tolerate failure or even slightly out-of-focus images, get in line for this Canon now.”
