This lens is optimized for macro photography between 2.5X and 5X life size. It is specifically designed with an extended working distance (45 mm at 2.5X and 40 mm at 2X) and a smaller lens barrel. The lens is much more compact and lighter than other comparable products. It also offers a relatively large depth of field compared to other extreme macro lenses on the market. The Laowa 25 mm f/2.8 2.5-5X has been developed for professional and recreational macro photography, making it suitable for use in nature or indoors.
