Following on from Neils thread (if you can't beat 'em, join 'em).
Took the first pics recently of, yes, you guessed it, kites in flight - plus one perched on the now familiar tree (approx. 150ft away)
It suspect it will take me a while to get used to panning with this lens! I also need to work on my exposures etc. Apart from that, I find the lens pretty comfortable to hand hold when snapping away. Yes, it can get a little irksome when standing taking flight shots for ages, but overall it's a great lens, and I'm certainly happy I bought it.
(I couldn't resist taking the one of the aircraft, as a kite flew below, crap pic but it made me smile).
