Question about Tokina AF 80-400mm f/4.5-5.6 ATX840AF Autofocus Lens for Pentax AF
I seem to have problems getting sharp focus with my Tokina lens on the D70. It works fine with a Nikon 18-200 but on recent wildlife shots there was no in focus aspect at all - yet OK on others. High shutter speeds seem to make little difference although I do have to get down to an aperture of 5.6 to get good speed. Even with poor depth of field at that aperture, surely some of the picture should be in focus?Do I need to work only with smaller apertures?Focus is set for the single, centre point and the camera always says it has acquired focus,

Most likely something bad has happened. It out of warranty, usually its 5 years. This is a pro job, getting to anything inside a lens is a very special job. There are a number of places to send it out. Check http://www.acecam.com/srindex.html and write to one or two of the places for estimates. It could be $150 or more plus shipping and taxes. A new one is about $400+, you could check around the many on-line camera stores for a used one. Could be a simple electronic part or the iris blades are bad.
