Finally a manufacturer has decide to come out with a constant f/2.8 zoom lens for Canon & Nikon crop sensor camera.
Tokina AT-X 116 Pro DX
This is one focal range all crop sensor camera had lacked of a large aperture lens. I wonder how this Tokina lens will fare in the image quality department I think this could be a winner for Tokina, as both Canon and Nikon or any other 3rd party does not have a similar lenses with constant f/2.8 yet. Maybe others will follow suit soon
