Cheers Matt and Peter… it was another 75-300 i was trying for a M8 to see if it was ok, getting a new 2x teleconverter today, so, have to try figuring that out now:confused:
scott i have a 2 x converter and it only really works on M focus
i have found out tho if the cameras mounted on a monopod then the auto focus works if theres enough contrast
hope this helps
regards
peter
