18mm f/3.8 Super-Elmar-M ASPH
The 18mm f/3.8 Super-Elmar-M ASPH lens was introduced in 2008361 (or 2009286 ). The lettering has shifted from the sharp, digital style to the rounded forms reminiscent of the classical Leitz era361.
The design of the mount is based on a modern engineering approach, where components are manufactured to precise tolerances before assembly361. This technique reduces the need for manual adjustments and the selection of suitable parts during assembly, guaranteeing a consistently high level of quality361.
The lens production started in 2008 and the lens has the catalog number 11649361. The construction includes 8 elements in 7 groups, with one element having two aspherical surfaces361. It provides an angle of view of 100º and has a minimum focusing distance of 70 cm361. The lens weighs 310 grams and requires an E77 filter, which can be used with filter holder/adapter (catalog number 14484)361. It is available only in a black anodized version and includes a 6-bit lens identification361. Additionally, the lens comes with a separate, screw-on type lens hood that includes a stop361.
