Finally! Finally a full frame compatible 24-70mm f/2.8 image stabilized lens has been announced!
Tamron has today announced the Tamron 24-70mm f/2.8 Di VC USD Lens
, featuring a max f/2.8 aperture of the entire focal length range along with ultrasonic drive AF and vibration control.
There is no question that a huge demand exists for a lens spec'd as this one. The image quality and autofocus accuracy of this new lens remain the two biggest questions in my mind.
