This is a little video in which I show you a comparison between the Canon EOS 20D, 1D Mark III and the 5D Mark III in terms of:- Shutter sound- Rear display- CropfactorOn the 5D you first hear the 6fsp in 'normal' mode. Then the 'silent' 6fps in Live View mode and then the 3fps in regular Silent mode.The pictures on the end were taken with the 70-200mm L II lens at 200mm (identical manual settings on all cameras, shot in JPEG and resized in Photoshop).
