This D-FA*70-200 is the only * optics in their FF stable and is pretty much guaranteed to perform like their other * optics.
But there is nothing like 50-135 out there given its weight, WR and IQ. period.
I covered a 5k race with mine a couple of weeks ago. Definitely not my first choice due to focusing speed. But I was itching to use the lens. Results (outside of a handful of misses) were rather remarkable. Kept it stopped down at f/5.6 and the shutter speed at 1/750s. Portraity runners.
If anything, I'd only want a faster and more accurate focusing motor/system on the 50-135mm if it ever got an upgrade -- optically it is rather nice (even at f/2.8). Pondering switching it to screwdrive, I bet that would make it focus a little quicker.
I think the motor in the D-FA is much more 'pro' than our aging SDM system. Really interested in seeing reviews with it on a finished K-1. Could make many a wedding photog happy.
