I agree. But in real golf you are able to see things a couple hundred yards away and don't really need to zoom. Also, in real golf tee boxes aren't always smack dab in the middle of the box.
That is one thing i wish the developers could find a way to incorporate moving the tee markers around on the box and creating different angles for tee shots from round to round. That is one feature i'd love to see and it would really change the difficulty in my opinion.
