laconi's zx-10 and corser's r1 were flaming pretty much every lap at coppice. got a nice series of three shots of laconi on one of his passes through the turn.
it was intentional, but was only my first go with the 70-200 sigma, bought a 2x convertor for it too, which should be arriving tomorrow, giving me enough time to get to grips with a 140-400 lens before heading to silverstone for the bsb this weekend!
I just got the 70-200 myself, but haven't officially christened it on the bikes yet. Let me know how you get on with the convertor. I'll be getting one before TT week hopefully.
& I look forward to your BSB shots
