    Difficulties with focus when taking birds in flight.

    I'm considering getting myself a flash meter and have been browsing the Sekonic website to figure out which unit will best suit my needs. I stumbled across this page.... http://www.sekonic.com/classroom/classroom_2.asp which demonstrates very nicely how you can nail your results perfectly by...

    Difficulties with focus when taking birds in flight.

    FWIW I've just uploaded an album of BIF shots taken with my 40D at Colchester zoo recently. Every shot here was taken using all focus points and I have included resized full frame images and 100% crops. They're not that great, because the birds were pretty lively and tracking them was a real...
