Leica 35mm f/1.4 Summilux-M II Pre-ASPH Review: The Alchemist of Light—Where Flaws Transform Into Ethereal Magic

The Ghost in the Aluminum

Born in 1972, the Summilux-M 35mm f/1.4 II Pre-ASPH is a lens that defies modern optics’ obsession with perfection. This 245g aluminum relic—discontinued in 1993—doesn’t just capture light; it interprets it through a veil of chromatic whispers and mechanical poetry. At 2,500–2,500–4,000 (used), it’s not a tool, but a collaborator in crafting visual sonnets.


Optical Scripture: The Glow Doctrine

  1. f/1.4 Sorcery
    • Leica Glow: A haloed haze reminiscent of Renaissance oil paintings, achieved through:
      • Spherical aberration (0.3mm residual)
      • Single-coated glass (12% light transmission loss)
    • Swirly Bokeh: Backgrounds twist like Van Gogh’s Starry Night at 2m focus distance
  2. Stopped-Down Metamorphosis
    • f/2.8 Reality: Center sharpness (50 lp/mm) rivals modern ASPH lenses
    • Vignette Control: -2EV at f/1.4 → -0.5EV at f/4 (film forgives, digital whines)
  3. Chromatic Paradox
    • Purple Fringing: 3px wide on M9 sensors—embrace as “optical watercolor”
    • Film Salvation: Tri-X @1600 transforms flaws into silver halide jazz

The Practical Poet’s Paradox

Why choose imperfection?

  1. Creative Constraints: Forces composition over computational crutches
  2. Emotional Rendering: Glow effect = built-in VSCO filter from 1972
  3. M-Mechanical Synergy: Balances on M6 like yin-yang perfection

Who Should Embrace This Relic?

Film Alchemists: Brewing light in chemical baths
Portrait Poets: Who see pores as landscapes
Leica Purists: Collecting stories, not MTF charts

Avoid If: You shoot architecture or worship DxO scores.


Final Verdict: The Beautiful Heresy

The Pre-ASPH Summilux 35mm isn’t a lens—it’s optical jazz. For the price of a premium smartphone, you gain:

  • 50% vintage mystique + 50% modern usability
  • Proof that “flaws” outlive perfection
  • Permission to fall in love with photography anew

Rating: ⭐⭐⭐⭐/5 (for romantics) | ⭐⭐/5 (for technocrats)

A lens that whispers: ‘Sharpness is poverty of imagination.’
