I'm not sports/wildlife or telephoto shooter (still learning to use the telephoto on my 12-100mm!), but I somehow I get the GAS feeling watching videos of this lens. Maybe it's seeing all those switches on the side, something really cool about that for some reason. Of course it is too expensive for me, but it probably would not be as interesting if it was a cheaper lens. I don't mind if camera companies make different products for different audiences. That's exactly what they should be doing, so I see no point complaining about it. It's not a lens that was made for my needs and maybe that's a good thing.
