30cm.

Tho this photo was taken with Medium Size setting -> 39602640 pixels.
Max size is 58003870, it provides possibly bigger magnification.
BUT the lens has tiny, tiny, tiny! depth of field.
Thus, to have more of the image in focus (like the stamps that I shoot recently a lot) I have to step back intentionally, and shoot from 50 cm and more - just to have more part of the object in DOF zone, with a sharper detalization.

Надеюсь, понятно объяснил. 30см есть, но снимать приходится не с минимальной дистанции.
