<p>Consider using a US$150 Canon 500D close-up diopter on a quality long lens you already own. This is a multi-element diopter, not to be confused with the poor quality commonly-found +1, +2, +4 diopters. Performance is very good, and may be all you need.<br />http://www.bhphotovideo.com/c/product/87503-REG/Canon_2824A001_77mm_500D_Close_up_Lens.html<br /><br />Another possibility is extension tubes that support full automation. Many available from the big vendors.<br /><br />Pros and cons to each:<br /><br />500D diopter - Relatively light weight, small physical size, very good quality, no light loss.<br>
Extension tubes - Relatively light weight, larger physical size, no loss of quality, but light loss requiring more exposure.</p>
