Very low flying helicopter taken with the D90+300 f4 ED AF (old metal model, non S)on the fly, so to speak, through the open roof window of the car. Really fun shot! This relatively cheap old model works wonders if well handled and is very sharp and light for travelling around. Also works well but with slower AF with the Kenco pro 300 TC 1.4 (the Nikon model won't work with this nikon model).
