Thanks everyone. Kind of a atypical setup here. 70-200 f/4 L + 1.4x TC, + 65mm of extension tubes Makes for one very LONG lens, which is difficult to compose because the weight pulls the tripod down. Difficult to focus too, because the dof is so shallow. These were both at f/8.
Good thing dragonflies always return to the same spot. If they flew away while I was trying to focus, I'd just wait until they returned
