Photokina 2014: Hands on with new Tamron lenses – including 15-30mm F2.8

I have to say that, Tamron isn’t quite on the sigma’s “art” prime lens level. 150-600 was more of a upgrade to sigma’s 50-500, but only minor. They make good lenses “for the buck”, like the 70-300 VC. What I fear is that this lens wont be “that sharp” wide open, which is area where it could have good potential versus the Nikon 16-35 f4 (low light action / movement, indoors / event).

But then again, I don’t know enough about their 24-70 2.8 . If that thing is sharp wide open, then it could mean they know how to make some lenses good..
