Long ago, it seemed worthwhile to include camera model product image comparisons in the camera reviews. Eventually, we had enough to-scale camera images available to put together a trio of comparison pages showing front, back, and side views. Today, the available images were overwhelming the simple tools and the next iteration of the comparisons is now live, condensed into a single tool: Camera Images Comparisons Tool. The tool is not perfect (some views are missing images that were not made available to us), but especially with the new "overlay" feature, I think you will find it very useful.
