Doug suggested i put my 100mm macro lens in front of the lens on my phone camera but I have to report it doesnt work. All you get is a white dot in a long tunnel and theres no focus at all.
Anyway while i was there I put the cameras light on and had a look inside the lens, and this is what I saw.

When you put two lenses, each designed to focus at infinity, together maybe you get double infinty? Very Happy
