Hi guys,
I recently switched to Canon as I always wanted to try the 400mm f5.6 prime. I bought a 50D with it but I am starting to wonder if the autofocus will be fast enough for airshows (F4 farewell and RIAT), so I was wondering if somebody has experience with both, preferably combined with the 400mm.
As I am posting anyway, I often had issues with the dynamic range of my D90 (either I had dark planes or white skies) and the 50D seems to peform less well on that level, is there a way to cope with this or can it only be fixed in post processing?
Thanks for your time,
Arthur
