I was wondering if there is a simple test I can conduct at home without any special equiment to determine if my lens is front focusing? I have had several shots that I thought were spot on when I looked at the shot on the LCD but discovered they were out of focus. I have tried it with both settings on my 60D - One Shot AF and AI Focus AF. I am shooting a staionary object but it appears to be hit and miss. I am using my 85mm 1.8.


Any suggestions would be appreciated.
