^- Well... i guess it also depends on "flagship" Sony seems to be targeting this at the A77 owners.. And ok, the A77 has 19-point AF (and hey, its not even bad!) but... yeah... my 7D is still more capable for what most people would use this kinda lens for because it can sustain its 8fps shooting a lot better without stalling out and dying...
Nothing in the Sony system has the right to call itself "professional", Why? they dont want the professional market, a Sony rep stated that pretty bluntly at one point, They dont offer pro-level support and their costs of repair and repair turnarounds are absurd, Not to mention their repair rate was fairly rediculous on their pro lenses, With something like a 33% rate over at lens rentals, compared to less than 10 for equivalent Canon/Nikon lenses..
I'm thinking Sony is fully cognizant of the fact this lens wont sell, even if it was priced down around its Canon/Nikon contemporaries, Sony's installed user base just on the whole isnt going to foot out for these big lenses, in fact I bet thats why its taken so long to market, its probably released now only because they didnt want to risk getting sued by one of their too-rich-to-know-anything users...
