You were apparently also making the assumption that the two cameras are using the same focal length...which is still left unstated, but the only way to achieve your scenario. Given that, then the two images are NOT "the same exactly image[s]", which is one of the problems I was having with your explanations. This is simply an increase in magnification, which is what you are doing by shooting the same focal length with both a 1x and 1.6x camera and standing in the same spot. Similar to shooting an 80 on a 35mm vs shooting an 80 on medium format. You obviously need to use a 1.6x longer focal length lense on the 1x body, then the images would be "the exact same image[s]". I believe that this (focal length to imaging media and magnification) is a basic concept and am curious why it warrants saying (at least in a group like this anyway). That, combined with the use of "the exact same image" made unclear to me what you were talking about, since again, the two images would not be "the exact same image[s]". But, none the less, we've filled in all the blanks through interpolation ;-) and your point is now clear. A simple concept clearly overcomplicated. Thank you for the clarification. Case closed.
