This is still one of my favourite images. It was taken with a Canon Eos 7D that was modified for UV by ACS in the UK, using one of their own filters. The lens was a Zeiss UV Sonnar on about 80mm of extension tubes to allow me to get closer to it, and below is the full frame shot and a cropped version. I was laying on the ground for this, with the camera balanced on a plank of wood, as my tripod wouldn't go low enough. I was sliding the camera back and forth to try and hit focus.
