The AML-2 49mm Macro Lens from Sigma is an adapter that mounts on the Sigma DP-2 and provides a dramatically reduced minimum focusing distance, allowing you to shoot subjects just inches away from the lens. Its compact, lightweight design allows anyone to experience the fun and ease of switching lenses, without the added bulk and expense. The exclusive design delivers outstanding image quality from the center of the screen right to the edges, and does not compromise the quality of the DP Merrill's built-in lens.
