pre-asph
Leica leica 50mm f/1.4 summilux pre-asph e46 version continues the optical part of leica 50mm f/1.4 summilux e43 version. The e46 version was sold from 1995 until it was replaced by the asph version in 2004. Usually this version of e46 is also called pre-asph.
The difference between E46 and E43
The E46 version has a minimum focusing distance of 0.7 meters, while the E43 version is 1 meter. The gap of 0.3 meters has little effect on street photography, and has a great influence on portrait photography. Because you can get more bokeh at close range. At the same time, 0.7 meters is more practical than 1 meter in a narrow environment.
E43’s hood is external. E46 has a built-in hood.
Image quality
The E46 version is consistent with the E43 style, with large contrast, good sharpness, natural tones, and good bokeh. Some people say that pre-asph is more suitable for color film because of the large contrast. In fact, the contrast of the E43 version is also very large, especially the e43 produced in the 1990s. Contrast is related to the coating. Information shows that Leica has been working hard to enhance the coating, the purpose is to resist glare.
