I assume you were responding to Austin and not me, because I was talking about Planar 100mm f/2.0.

Bingo. And the price. And speed of AF.

Not too many pros though. If you use NPS160, Provia or even Velvia - forget about it. Some people would use NPH, but it all depends on purpose. And still, if you had f/1.4, you could use ISO100 film in the same light conditions where you would need ISO400 at f/2.8.
Also, I recently started getting back into B&W, and just think about it. You get Ilford HP5, put red-orange filter on, and you lost two f-stops. Your ISO400 is now ISO100 ! Oopsy-daisy, f/2.8 might be too slow.

They buy a lot of things to test-drive them. It's the nature of their business. They always want to outdo the competitor, thus they try to find what works for them.
By the way, I guess you're lucky. I have never personally met pros using Contax or Leica.
