I got the Sports version and it took 3 months to get it from B&H, however the wait was well worth it. My sigma worked perfectly from day one with tack sharp images on my D810. I had the Sigma 50-500mm and the 150-500mm and at the top end 500mm could never get clear images out of them even tried AF fine tune without any results. The 150-600mm is a great lens giving me excellent results that I never got with the other two Sigma lenses.

Did you get the contemporary or sport? I tried the Tamron 150-600mm but found it no better than my Sigma 150-500mm in fact I think my Sigma was better. Next week I will get my grand-daughters to look at the pictures with their young eyes. Mine are getting a little old. I also think the Tamron was soft over 500mm like others have stated. I sent the Tamron back and have been waiting for the Sigma. I wish they would cancel week ends when I order something.
