Though I'll admit that I'm more partial to the Summilux series of lenses, the Leica 35mm f2 ASPH Summicron is surely an option that many photographers using Leica or other cameras will want to consider in part due to its pretty darned affordable price point.
Introduced just a few years ago, the Leica 35mm f2 ASPH Summicron and in general the 35mm f2 lenses from Leica have been a favorite of many photographers for the bokeh. But if you ask me, I'd like to think that the Leica 35mm f2 ASPH Summicron isn't better than the Summilux version and that this option is really just for the film photographer that wants something on the more affordable side. It's a nice lens for sure; but at the same time, it's also, well, boring. By that, I mean that I don't see or feel the magic of this lens that I have with many of the company's other optics. . thephoblographer.com
