I recently switched from sony to canon. I'm still getting used to the new interface. One thing I can't figure out is how to magnify the preview image. It appears that the magnify button is set to Focus Select while in the preview. Is there a way to magnify the preview without going into the playback mode? On my Sony if I hit magnify while the preview was still being displayed, it automatically went into playback mode. I often used this to check focus. Is there a way to set the 5D Mark II to do this?
