A dedicated macro lens, such as the Vivitar Series 1 90 mm f/2.5 shown here, is one of multiple methods to achieve the large reproduction ratio required for photomacrography.

…i.e., at closest focus) of approximately 1:10 for practical and optical considerations. Reproduction ratios much greater than 10:1 are considered to be photomicrography, often achieved with optical microscopes. The term photo-macrograph was proposed in 1899 by W. H. Walmsley for close-up images with less than 10 diameters…
