My preference for macro work is, in decreasing order of preference and optical quality, but increasing order of convenience and versatility: A true macro lens Extension tubes Achromatic (2-element) close-up attachment I think the extension tube is optically preferable to the add-on lens, but not as convenient. The best thing about the add-on lens approach is that you're able to use it on a zoom, which allows you to change framing easily without moving your tripod around. -- Mark Roberts Photography and writing www.robertstech.com
