Mexican Monarch shot with the 400 f5.6L and 65mm of extension tubes. I also dialed in -.7 EV of exposure compensation to keep from blowing out the flowers. I ended up pushing the exposure in the RAW file probably .2 EV to get to what you see here. DOF is very thin with the tubes, notice how just the eyes/antennae are in focus. I'm about 10-12' away here, any closer and the little buggers take off.
