Hello, I have a ef 28-70mm II lens. Unfortunately the auto focus has stopped working. As the lens didn't cost me a lot when I bought it from Ebay, I thought I'd try to repair it myself. Does anybody know if there is an "EF Lens Repair Toolkit" available, or which tools would I need to take the lens apart? I have jewellers screwdrivers, but some of the screws seem very small indeed. Many Thanks, Nick.
check out youtube note that the philips looking screws on lenses could well be japanese industry standard ones (JIS) they are profiles different in the head
