No problem - almost all lenses do that, especially longer lenses - focus beyond 
infinity, to take care of the different heat expansion characteristics of the glasses 
and barrel materials so that you get infinity focus whatever the temperature.
All the best!

Aihe: Infinity Focus problem

>I have a lens that is little off when attempting to focus to

>Does anyone know what causes this?  Does this indicate that
