I was looking at John Lamb's beautiful pictures of New Zealand (www.pbase.com/john_lamb) and noticed he used a Nikon 12-24 f/4 lens for some of his shots. They just look perfect but I heard quite a few bad comments on this lens, namely that everything beyond 25 feet appears out of focus. Any comment?[a href=\"index.php?act=findpost&pid=138524\"][{POST_SNAPBACK}][/a]
