With the Super-Elmarit-R 15 mm f/2.8 Asph (launched in 2002), Leica's developers managed an engineering feat: despite its increased speed, they were able to make the lens 100 grams lighter than its predecessor, the Super-Elmar 15 mm f/3.5. At 710 grams, it was still far from light-weight, but the weight reduction made a noticeable difference to the handling of the lens.
The closest focusing distance of the Super-Elmarit-R 15 mm f/2.8 Asph was 18 cm, as opposed to the 16 cm offered by its predecessor. Nevertheless, with its two aspherical surfaces, 13 elements in 10 groups and internal focus, it represented the most up-to-date developments in the construction of extreme wide-angle R lenses. The Super-Elmarit-R 15 mm f/2.8 Asph was manufactured until 2009, when the entire R system was discontinued.
