Singapore swing

Ferrari needs to practise more than just pit stops nowadays, but this is from 2012, when the team managed to sustain a title challenge all the way until the Brazilian finale... and then lost. I have entered a similar shot in a previous competition, but that was from Monza and this is a routine pit drill from Singapore. Taken hand-held at 1/6, with K-5 and 'a lens'. I suspect it was the DA17-70, although the EXIF data suggests a 16mm focal length and that doesn't tally with very much that I've owned (save the Sigma 10-20, which rarely gets taken to races and closes only as far as f22 rather than the f25 indicated here). A bit of a mystery, but the 17-70 does sometimes give strange readings...
