I shot this on the C&O Canal at the aqua-duct. I used my 70-200mm with an extension tube so I could use it like a macro lens and not fall in the canal. I like the extension tube, but I don’t like the fact that you lose infinity. This means that every time you change the focal length on this lens, you have to move your body in or out to pull focus. Not very wise when you’re leaning over the edge of a canal.
Tech:Canon 40D, 70-200mm L 4 is, ISO160,f/4@1/250
