Class F-1 is a little of both. It covers mental visualization, and moderate sight. If it's just basic sight (a glance through a minute of sight), it just falls under Class F. Mental visualization and moderate sight (which I'd say as falling between a minute to three tops) fall as Class F-1. Anything longer than three minutes is Class F-2.
