What is the benefit of the sensor marker?

Question

I know that this marker on my Canon EOS shows me where my sensor is:

image showing camera body

Form technical point of view this is interesting, but is there benefit for me as a photographer to know exactly on which level my sensor is?

Is there a similar marker on DSLR of other brands, like Nikon?

To answer your second question. It's the same marker pretty much everywhere, and it's on all serious cameras of any make (including Nikon, etc...). — Fake Name, Dec 01 '13 at 13:50

Hmm... the recommended duplicate isn't asking the same question, it's just by chance that the answer there contains relevant information. — Joanne C, Dec 01 '13 at 22:47
@mattdm. Thanks for the links to the other questions -> Helps me also. Thinks that is not a duplicate in question self, but sure the answers overlap. — Micha, Dec 02 '13 at 09:54
@John From the other question: "... and what is it used for?" — mattdm, Dec 02 '13 at 12:05
@mattdm - But buried though... I think they're similar myself. — Joanne C, Dec 02 '13 at 12:40

it is used to precisely measure the distance of the subject from the camera. so you can adjust the focus on the distance scale on your lens. it is also used to determine(calculate) the reproduction ratio / Macro Mode Maximum Magnification.

Thanks for answer (+1 for that). Very interesting point. So you need the marker (only) for very precise measurements? – Micha Dec 02 '13 at 09:56
