When the parcel arrived and the lens with me called THE BEAST, finally on the D750 was, it was of course immediately out into nature. It really is extremely sharp, and the first shots from the hand with stabilizer without large brooding over the correct camera setting my expectations as auto focus, color and sharpness have far exceeded. I can not imagine that there is anything like it for this price. High praise generally at Tamron, which many great lenses are managed lately. So I have been a few days, the Tamron SP 70-200mm F / 2.8 Di VC USD Tamron SP 24-70mm and the F / 2.8 Di VC USD, with whom I am very satisfied so far and - up, except for the price - are hard to beat Nikon. After these encouraging Erfahriungen is tomorrow the Tamron SP 15-30mm brand new F / 2.8 Di VC USD lens complement my park to a real wide angle.
