Simply the most expensive there is or the equipment the Pros swear by or by the amount of features or by coverage by media or specially custom camera or something else?
With Nikon D3x being $8k in foreign currency, is it expected that respected Pros must switch to the the D3x to maintain their status or the expectations of the clients who understand only "if want best photos must use best camera" and usually is most expensive Nikon has.
In general, will the Pros lose customers to others who switch to the newest highest end while they retain their current system?
Even the Sony A900 is reasonably priced with the features it offers and Sony is relatively a newcomer to DSLR. Can consider as a Pro body?
