G'day all,
Thanks again for your input, I have never had so much help in my 30+ years in this hobby since I joined IIS. It use to be one of the disadvantages of being in the country and isolated; but not any more.
The lens is a Canon EF 50mm f1.4 with auto and manual focus. Last night was the first time that I had used it on manual focus. Next time I will use the LCD screen to check focus.
