Overview
The Leica Summilux-M 50mm f/1.4 pre-ASPH represents Leica's fast fifty before aspherical elements arrived. Multiple versions exist — the pre-ASPH models have character the clinical ASPH versions lack. Dreamy wide open, sharp stopped down. The romantic's Leica.
Verdict: The romantic's fast fifty. The pre-ASPH Summilux delivers character and glow that clinical modern lenses can't replicate. If you want perfection, get the ASPH. If you want soul, get this.
