That must be one responsive lens! It is hard enough getting a bird coming towards you.
Of the shots you have posted this looks to be the highest degree of difficulty to my eye. Well done. john We're off to see the Lizard~~the wonderful (sic) Lizard of Oz~~
thanks John. yes it can be a bit tricky catching them as they come right at you. The hardest ones though beleive it or not are the prop aircraft. they are still moving at 200-300mph and you have to slow the shutter speed right down to avoid the props freezing and making it look as though the aircraft is just hung there. that becomes expecially difficult when the aircraft is heading straight for you.
