Shooting with Tubes

Here\'s a shot I took last autumn shortly after picking up a set of extension tubes. I was mounting them on all of my lenses as I learned how best to use them. In this instance I\'d mounted a 20mm tube on Nikon\'s manual focus 50 f/1.2 AI-s. The focal plane in this setup is only inches in front of the lens and stopping down didn\'t give me much in the way of depth of field. I was wandering around Sausalito when I saw this rusted bolt and thought I\'d give it a try... I do enjoy rust! I post this simply to demonstrate that tubes don\'t require flowers... or bugs for that matter.

Without a tripod and with such a narrow focal plane the best I can do is slowly rock back and forth until what appears in the viewfinder seems sharp. Even pausing to check the focus confirmation light is hardly helpful since the slightest movement loses focus. And yet, I enjoy doing this kind of shooting.
