This is an in-depth review of the Tamron SP 24-70mm f/2.8 DI VC USD – world’s first image stabilized standard zoom lens for 35mm sensor cameras that was released in April of 2012. I have been shooting with the Nikon 24-70mm f/2.8G for a while and although I love it for its super fast and accurate autofocus and durability, it has its share of problems. It is huge and heavy, has rather poor corner performance at fast apertures and suffers from field curvature issues (where sharpness is not uniform across the frame). In addition, it lacks image stabilization, which I am a huge fan of. So when I found out that Tamron released a professional 24-70mm f/2.8 lens with image stabilization, I knew I wanted to test it out and compare it head to head to the Nikon 24-70mm f/2.8G.
