I was just sitting with a tripod, canon 7D ii and the 100-400 ii with a 1.4x extender. I also used a flash with a multiplier lens since the subject was in the tree. I was after the wasp but just as I pressed the shutter the fly landed. The wasp tried to attack the fly but miss. It was amazing that the poor fly had no clue that wasp was there.
Two for one is always a nice in nature photography, especially when we aren’t expecting it, Dean.
