Mightier than the sword

Found my extension tubes so I decided to try them out today. Pretty weird set up. 50mm f1.8 reversed onto a 100mm f2.8 attached to 68mm of extension. It cranks up the magnification quite a bit. Flash is off shoe again. This is a freebie pen. That lint was left over from me wiping the tip with a tissue prior to the shot. 100% crop below for scale.
