I received a FC-E8 Fisheye for my old Nikon Coolpix 5000.
It requires the UR-E6 Adapter with the Coolpix.
I don't find it very useful for my use but it can take some funny photos :)

To do it better I need to bring the lens closer (to the point of touching him) to the soldier's nose but I didn't dare to do it...

That's funny!I can see your feet :D

It is very hard not to have your feet or jacket in the photo!
Here's another one:

I was at 5cm from his hand.
