Congrats on your purchase! Enjoy your new equipment.
The Tamron 24-70 is a nice and sharp lens in my opinion. Decent AF thru the optical viewfinder. But quite slow to acquire focus while in liveview. Video wise it is rather smooth. But a little noisy. I have only tried three lens. 50 f1.8, 18-55 kit lens and the Tamron. No complaints for the Tamron at all. I love the sharpness it gives me.
