I wonder what practical use cases are there for 1:1 imaging with all the digital tools we have nowadays? Since objects that are exactly the size within the range of that of a sensor are few and one usually doesn't take pictures that close up to the objects?
Here is an interesting article on actually focusing in real-life macro photography. An interesting issue is that at this magnification, moving the camera forward or backward just a few millimeters at a time is more than enough to throw the entire photo out of focus, and even if you do focus successfully, the depth of field will be remarkably small. In fact, it can be impossible for the head and body of an ant to appear in focus simultaneously! In the dragonfly example photo on the left, notice how the entire body is approximately the same distance from the camera.
