I am considering investing in a macro lenses. From my reading a lense around the 100mm range is a decent starting point.
The 2 I am tossing around are the Sigma 105mm F2.8 EX DG Macro which I can pick up for about $600 or a Canon 100mm f/2.8 Macro USM Lens which is nearer the $800 mark or more.
Anyone had experience with these 2 and can they give any advice especially with regard to if the extra $$$ for the Canon will make a difference.
