Overview

The Leica Summilux-M 24mm f/1.4 ASPH is the fastest 24mm rangefinder lens, offering high center sharpness even at f/1.4, but with softer corners and field curvature that benefits interiors and streetscapes. Distortion is wave-type and noticeable on buildings. It is large and heavy at 500g, requiring an external viewfinder. The lens suits photographers needing a fast wide-angle for low-light or portrait work, but its niche focal length and price make it less versatile for general use.
