The Tokina AT-X 17/3.5 is said to be outstanding. Unfortunately, Tokina has never made it in Pentax mount. The earlier Tokina SL-17 (RMC) is not nearly as good as the AT-X. Nor is it anywhere as good as the Tamron SP 17/3.5. It may even be the same as the Vivitar 19/3.5. The Tamron is said to be outstanding for its eerie lack of distortion. It has two shortcomings: low saturation and contrast, and lack of sharpness below f/8, at least in the corners. Well, on a DSLR, saturation and contrast are easily recovered after the shot; and the Tamron won't be using its corner glass, just the center, so sharpness across the frame should improve.
