They end up sending in both lens and both to calibrate both, which if under warranty Canon should do for free. Chris NOLA ----- Original Message ----- From: "George Lottermoser" Subject: Re: [Leica] potential focus issues Ruff test: Lock it down on a tripod. Pick the center focus spot. Focus on 18" on a yard stick at 45? This should indicate whether the lens is back focusing, front focusing or dead on. Once you know that - more discussion can follow. Regards, George Lottermoser
