Lens and Extension Tubes
Dec 12, 2012 18:06:07 #
I have a set of Kenko Extension Tubes and a 50 mm lens. Is there any way I can use these to simulate a macro lens? I don't have any experience with the extension tubes, but just purchased them since a true macro lens was out of my price range for now.

A Kenko set consists of a 12-mm, a 20-mm, and a 36-mm tube. Try them individually, and in various combinations.
Disable Auto-Focus and set your lens to Minimum Focusing Distance (MFD). Attach a tube or combination of tubes. Physically move camera/lens combo in-&-out toward subject. When in focus, take your shot. If you can, guesstimate Working Distance (between lens front element to subject).
Photograph a metric ruler, so you can document your field-of-view, to determine your magnification.

Thanks, Nikonian! That was the specific direction I was looking for. I'm trying out a tabletop studio kit I have on Friday and would like to see if I can attempt a true macro shot.
