Took shots of a couple of crane flies a couple of evenings back. All of the shots are un-cropped. I just managed to get in right up close on a couple of them with the 100mm and a 20mm ext. tube. 
A little closer
Different Crane fly
Again, managed to get in a little closer. They're quite chilled about it
This one I think is my favourite. This is set at 1:1 mag but with the 20mm tube on (so whatever mag that is)
And finally... yet another green bottle fly. This one surveying the colourful land ahead
