Sony has a 300mm f2.8 and 500mm f4, so it's not a million miles behind. The system as a whole is getting pretty compelling TBH. Using a camera that can focus track and calculate exposure at over 20fps with nearly 700 auto focus points across almost the whole frame would for sure let me capture stuff I couldn't on any other camera. And that's not to mention the silent shutter at this speed - I could literally capture photos I wouldn't be allowed to (golf anyone???) with a mechanical and noisy shutter. Even if I did it on a 500mm f4 and cropped in some of those 24mp! I'm a Nikon guy (well, I did shoot with the old a900 and some Canon/Olympus stuff too) and I'd certainly consider working very hard to deal with any lens short comings with a camera this capable.
