Top 12 Tips for Macro Photography – Make a Standard Zoom Focus Closer
2. Make a Standard Zoom Focus Closer by Adding Tubes
Extension tubes fit between the rear mount of the lens and the camera body to make the lens focus closer and therefore produce a much bigger image of a small subject. This image of a thick-legged flower beetle was shot with an 18-200mm zoom lens and a 20mm extension tube added. This is a much cheaper alternative than buying a macro lens but tubes are more fiddly to use in the field. Also, with an extension tube fitted you lose the infinity end of your focusing range. Add more tubes and this becomes increasingly more limited.
