When you shoot a photo, your picture is displayed onscreen. It's said to be possible to zoom in the picture, but pressing the zoom buttons do not zoom but activate their second function. So is it possible to zoom inside a picture when reviewing it just after shoot, and is it possible to zoom to the 1:1 level in one press ?
My question is mainly about the EOS 400D, and xxxD models, but any feedback about higher-end models will be appreciated.
