An Exercise In Futility

There are two things i dislike about this camera we have, and they are both to do with manual focus. One is that the focus ring has no markings, so it is not possible to set the focus to infinity. Maybe a focus reticule would help in that case - and that is peeve number two. On our old Minolta there was a reticule in which you had to align two images that appeared in two half circles - and that would indicate that the subject was in focus. I am barely an amateur photographer but it made sense to me that this would eliminate any focus error that would be introduced by my eye (which focuses independently of the camera). On manual focus with no focus reticule to assist me, i am having to guess when the subject is in focus. Or am i fooling myself?
