Have shot my first real attempts at macro photography. Would like some constructive comments. These were made using a Canon Rebel T1i with Canon 55-250 with Canon closeup 500D attached and a Speedlite 430 EX light source. The ISO was 100 using manual at f32 @1/200. The sea urchin is on a platform that is 22mm in diameter. Is this lens sufficient or would I do better with a dedicated macro lens. Thanks for your suggestions.
