Karl, I'm holding back on this lens for now as I have different priorities in saving for the 200-400 at this time. So I'm looking forward to your impressions as maybe it will save me $11,000 in the end
You better save quickly, likely the Canon will go up as will the Tamron if it is the hit we are hoping for.
I really don't feel much to worry about on IQ, I don't expect the AF to be as fast as an the 'L's' we are comparing it to, sure there will be some minor shortcomings perhaps but I can deal with that easier than another $11k
I will sincerely share what I have when I have it!
