Title: The perfect tube?
Review: Imagine, autofocus through an extension tube! This one is just the write size to give you the little extra close focus for copy work or nature photos. Highly recommended! Of course, if you opt for the longer tubes expect lens focus to become irrelevant, you will have to move the camera and use focus confirmation to help out.
