I whipped out my Olypmus OMD EM5 and slapped on my manual focus Minolta Rokkor 50mm f3.5 Macro lens with an extension tube in a hurry because even though it was small it had a spring in its step and was covering the small distance of the chair arm rather quickly.
I snapped a few shots of a blurry beast and then noticed that the only thing this itsy-bitsy guy had going for it was his size. The images I snapped did not do justice to the size so I dug into my pockets and added a penny. He jumped as the humongous metal disk was placed gently near him. Then he proceeded to escape at full speed. Luckily this was epically slow at his size. So I moved the penny around until I captured him just right in focus near it. Success!
