Got out this morning before the humidity reached stratospheric levels. Went back to get more shots of the Great Crested Flycatcher fledglings, and still haven't nailed my perfect shot. This one is close, just the damn leaf blocking the tail feathers ruins it

One from 2 football fields away, not posting for IQ purposes, but b/c I thought it was funny: a hummer buzzing the flight tower at over 400 knots

Testing the 1.4 TC.
Observations:
- f/8 is a challenge in the shady parts
- AF loses a bit of edge. Speed to acquire focus kind of reminds me of using the 2.0 TC on my Canon 600
- barely any loss in sharpness
