This is category in which there is no room for compromises in any aspect. It is intended only for those who live from photography. It differes from middle DSLR class by even larger software and hardware capabilities, body protected from weather influences, shutter with longer lifetime, and of course price which is sometimes so high that it seems unreal. But sill, really looking to who it is ment for, this price class isn't even so high.
