Quote:Nikon has to respond to the IDX MKII ............ Why would a pro sports shooter now choose the the D5?... because pro (sports) shooters have tens of thousands $$$/€€€ tied up in long lenses and other stuff, so they wouldn't jump from system to system every time a new model comes out from either, would they? Especially since on the surface of it, both bodies seem more than capable. I'm pretty sure not many people are going to switch - taking huge losses on reselling - based on these announcements. I'm also pretty sure that both units will be used with great results by the (well-off) owners of each respective system.
It looks to me like switching systems because of every new rad unit is like getting divorced after meeting every new hot girl.
Most of the local pros I know haven't switched systems in years. Some bailed from Canon after Nikon released D3/D4, but that was it. Some were forced to switch to whatever their agencies were buying en masse at every given moment. Say, TASS went all Nikon a few years ago but lately I've seen one of their local shooters brandish a 1D X / 5D Mark III, sometimes an Olympus E-M5 (that is presumably his own); another came in from Reuters with a bunch of top-level Canon fare and stayed this way.
