Leica Camera is pleased to introduce the Leica Summilux-M 28mm f/1.4 ASPH, the first Leica M-lens to combine an initial aperture of f/1.4 with the popular 28mm wide-angle focal length. This high speed wide-angle lens offers photographers high imaging performance with an unmistakable visual signature.
The Leica Summilux-M 28mm f/1.4 ASPH. rounds of f the range of high-speed M wide angle focal lengths.

With its exceptional contrast, the lens delivers the same recognized high performance level as the Leica Summilux-M 35mm f/1.4 ASPH., and in some respects actually out performs it.
