The lens is designed to cover APS-C sensors, and will come in both Canon EF and Nikon F mounts. Though it's not a huge range, and Tokina makes an inexpensive 11-20mm f/2.8, the fact that this is an f/2 is insanely impressive, and it's a testament to improved technology that we're getting such fast lenses at wide focal lengths, with great optical performance. This is about as fast as you can get for a zoom, and while their are some super-fast Sigma lenses, nothing quite hits this wide and this fast. 

Here are more of the specs:

  • Canon EF or Nikon F Mount (APS-C/DX Coverage)
  • Aperture Range: f/2 to f/22
  • One Plastic-Molded Aspherical Element
  • Two Glass-Molded Aspherical SD Elements
  • Two Super Low Dispersion Elements
  • Multi-Layer Anti-Reflection Coating
  • Internal Focus; One-Touch Focus Clutch
  • Nine-Blade Diaphragm
  • Price/Availability: TBA

Instead of a physical switch between manual and autofocus, you pull down or up on the focus ring depending on what you're trying to do. This lens should also do a better job reducing flares, and it focuses completely internally, so there's no telescoping action. We don't have any word on pricing or availability yet, but I would expect this to be under $1,000 based on how inexpensive most of Tokina's other lenses are.
