One more in the "not a bird" category that I came across today on my lunch and just had to share. This male carpenter bee hung around long enough for me to practice some up-close BIF (bee in flight ) shots with the more nimble 400L f/5.6 and a 36mm tube, before I swapped over to the decidedly more deliberate 500L on the same 7DII + tube setup.
Final shot here was at probably 7-10ft. 1/8000 on the shutter isn't enough to totally freeze his wings in flight! I do still enjoy the slight blur at the tips, with the wonderful blue-ish reflections, though.

I love this shot!
