I have a Canon EOS400D and Canon 10-22mm lens. Great zoom range, horribly soft and out of focus corners. Using a Tokina 10-17mm Fisheye will obviously improve corner sharpness but I lose a lot of zoom range. I will not normally need the 10mm of the Fisheye.
Is there a teleconverter that you can use with the Tokina 10-17mm lens? If so this would bring the zoom range to something more useful for me, but still have sharp corners. Has anyone tried this option?
