ZEISS Loxia 2/35

Here's what ZEISS says about this glass: "Light, unassuming, and reserved Loxia® 2/35 offers an extended field of view. This makes it the first choice for showing a subject in their environment or establishing connections between people. Like in reportage or street photography, for example. That’s what makes it the most important focal length for the genre in compact 35mm cameras."
