cheers
Since 500 f4.5 shows no AF on either TC then it looks like I'm going to have to go Nikon for a long lens, was hoping to upgrade to a K-5 and use the sigma but it may have to be a Nikon 500 f4 because i want the flexibility of that extra bit of reach

I can also vouch for that. Surprisingly well too!
