    Its a excellent lens patent, but it’s EF and not 1″ sensor

  • I will be very happy when this becomes available as i have a full frame camera, and it will negate my other two lenses, its a real hassle when out shooting to have to change from a wide angle to a zoom! As long as it reviews well with the independent review sites, and isn’t going to require taking out a mortgage for it, I’ll be in the market for this!
