Soviet Lenses: Introduced as far back as 1950s, most of these lenses were based on Carl Zeiss optical formulas, which gave them a solid optical performance combined with unique image characteristics, such as dreamy flares, swirly bokeh, and overall painterly texture that can only be produced in-camera! These lenses are surprisingly sharp in the middle of the frame and have a gentle focus fall-off at the edges. They deliver excellent contrast and vibrant colours in controlled lighting conditions, but when you allow them to flare, they truly come alive, and their character shines through!
