Thank you all for the interesting discussion. My problem is now solved, in a way I didn't expect myself. My local camera shop carried an A580 for the first time and I had a chance to try it out. Seems that Sony has tweaked the AF algorithm. With the A580, the AF doesn't hunt nearly as much as with the A700, the 70-400 now feels almost like a new lens.

Exactly, and this confirms IR review who say they tested A55 and 7D side by side and found the AF tracking to comparable. And Canon sensor technology is behind too.
