And that's your opinion which does not match MY opinion for MY one lens macro kit. > What make 300mm and 500mm true macro > lenses are you using?

The 300mm is a Canon 300mm F4 L IS and it focuses to ~4ft for 1:3 magnification which is just about perfect for large butterflies (even better with a 1.4x TC). The Sigma APO 300mm F4 AF MACRO lens I had before had very similar characteristics. I know at least one guy that uses the 500mm with a 1.4x TC and 25mm extension for butterflies. I have not tried mine in this way. My point is that 50mm is not long COMPARED to 300mm or 500mm. -- Christian http://photography.skofteland.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
