I like the odd macro shot, but don't want to spend money on a dedicated macro lens, so I thought about using one of the extension tubes from Fujifilm with my XF 35mm f1.4. However I don't quite understand what is meant by working distance when the tube is attached. I have looked at the diagram Fujifilm has made explaining the working distance for their different lenses with either the MCEX-11 or MCEX-16 extension tubes.
Would you be so kind to explain (in layman terms) what is meant by working distance? How far from the fromt element should my subject be and how far away from the front element can it be?
Thanks.
