The calculation above is based on the assumption that the optical center of the lens remains unchanged when the close-up lens is attached. This is clearly not true for a +10D lens. Thus the calculation is only approximate.

You might achieve better results by attaching an older moderate tele lens (90-200mm) reversed to the front of the 60mm macro. Probably cheaper too (but more bulky...)
