Nice shot Craig. Lots of pollen on the head!
Always a tough choice whether to mount my Kenko TC or just go with the bare 300 and crop. I tend to put the TC on the FA*300 only when the birds are more than about 12-15m away, and only then when the light is good enough. Putting aside the one-stop penalty of the TC, the longer the effective focal length the more it seems to eat light, and the AF performance does suffer.
