Sometimes it's to small to fill the frame.

The object were trying to photography that is ;) In that case we need to use a Macro lens, or in our case extension Tubes :) I took this Dragon fly pic the other day at the Basha Kill with a 25mm extension Tube I borrowed from Michele. That allowed me to get much closer to the "small subject" and still be able to focus. Basically the Extension Tube Attaches to the back of the lens and goes in between the camera and lens therefore changing the focusing range of the lens. Normally on The Canon 70-200 f/2.8 IS L the closest focus possible is 1.5 meters. With the 25mm Extension tube I can get much closer now. Maybe a meter or slightly less. I haven't measured it yet, but it's much closer for sure and now this shot below actually fills the frame. Without the extension tube the subject would be much smaller in the frame and it wouldn't be near as cool :) The best bet is to have a true Macro lens, but money talks and extension tubes are cheap!
