Hello, I've just registered to the forums, I think this is the most comprehensive Canon-related site on the net!


Currently, I have a Canon XSi with EF-S 18-55mm f/3.5-5.6 IS and EF 50mm f/1.8 Mk I lenses, and I've noticed that when I use Live view while in Av or Tv mode, the camera underexposes the image by 2/3-1 stop. This doesn't occur all the time, but in certain lighting situations (low light, light in front of camera). Why do you think this is happening? I guess is CMOS sensor metering vs dedicated AE-meter metering, but I'm not really sure. The point is, sometimes I'm shooting on a tripod with Live view and I have to re-take the picture because I didn't account for Live view underexposing the image.


Thanks for reading!
