Take into account that the lens focus may slightly drift while the lens is warming up from cold to
operation temperature. This is a typical phenomenon for projection lenses used with high brightness
projectors. The operation temperature of the lens is reached after approximately 30 minutes
projection of average video.
If it becomes impossible to focus the image, perform a Scheimpflug adjustment. For more info on
this, refer to “Scheimpflug adjustment”, page 65.
